A learner profile can contain an impressive amount of information and still leave a trainee unsure what to teach next. Interests, interview notes, language samples and a list of errors are useful ingredients. They become a teaching decision only when the trainee explains how they fit together.
For Trinity CertTESOL Unit 3, connect diagnostic evidence with a one-to-one lesson by tracing a clear route: the learner's intended use of English, what a suitable sample reveals, the priority selected, the lesson objective and the evidence used to evaluate it. A broad label such as “needs grammar” is a starting question, not a sufficient lesson rationale.

This guide concerns the Learner Profile in Trinity's Certificate in Teaching English to Speakers of Other Languages, CertTESOL. Trinity's public qualification information identifies Unit 3 as analysing a learner's needs and planning a one-to-one lesson. The public syllabus and qualification information were checked on 23 October 2026; use your validated provider's current assignment brief for the actual presentation and assessment requirements.
The public syllabus connects analysis of an individual English learner with a taught one-to-one lesson and recommendations for further learning. That connection matters more than producing an attractive description. A reader should be able to see why the chosen lesson addresses a need supported by the collected evidence.
This article's fictional learners, samples and lesson sketches are original teaching illustrations. They do not replace the real learner work or evidence required for an assessed profile. Nor do they establish a universal lesson format, a mark prediction or recognition of the qualification for a particular employment or registration purpose.
The Education parent guide examines learning that can be used beyond a familiar exercise. For a trainee, that means making a reasoned teaching choice when another learner brings different goals, evidence and constraints. A useful profile makes the reasoning visible enough to review and improve.
CHAPTER 2 OF 15 · Read the learner evidence
2. Begin with intended use rather than a topic label
Ask what the learner wants or needs to do with English. “Improve speaking” names a broad area. “Explain a change to a volunteer rota and check that a colleague has understood it” describes a communicative task. The second account helps a trainee choose relevant evidence without pretending that one task describes the learner's entire language life.
In an original case, Lina wants to discuss changes to a club timetable. She also enjoys reading fiction. Both details belong to her account, but they may have different implications for an immediate lesson choice. An interest can support engagement; it does not automatically identify the most useful learning objective.
Keep the learner's own priority visible. A trainee might notice a grammatical feature they have just studied and become eager to teach it. Before selecting it, ask whether it affects the learner's intended communication and whether the evidence supports treating it as a current need. The most noticeable error is not automatically the highest priority.
Goals also need interpretation. If Lina says she wants to sound more confident, ask which situations she means and what feels difficult in them. She might need language for clarification, a more secure account of time or a chance to organise a message before speaking. These possibilities require different teaching choices.
Do not turn the interview into a search for the answer the trainee already prefers. The learner's responses should be able to change the plan. If the evidence suggests that the initial lesson idea is less relevant than expected, revising it is a sign that the profile is being used, rather than merely written around a predetermined activity.
CHAPTER 3 OF 15 · Read the learner evidence
3. Preserve what each sample can show
A spoken interview, a written sample and a short comprehension task reveal different things. None should silently stand in for all language performance. A learner who understands an instruction in conversation may still need support producing a clear written message for someone who is not present to ask questions.
Suppose Lina explains her timetable successfully while pointing to a calendar. That is useful evidence of communication with that support. It does not establish that her spoken message alone made every time relationship clear. Record the calendar and the trainee's clarifying questions so that the account remains interpretable.
Now examine a short fictional written message. Lina states a new meeting time but does not say which earlier arrangement it replaces. The reader may understand the words and still be unable to update the timetable correctly. The difficulty concerns the completeness and relationship of information, rather than necessarily the spelling of every word.
Keep original samples distinguishable from corrected versions. A polished rewrite by the trainee can illustrate a teaching point, but it is not the learner's original performance. If the account replaces the sample with the correction, the reader loses the evidence needed to understand the diagnosis.
The next step is to state a limited finding. For example, the supplied message leaves the old and new arrangements difficult to distinguish. That is more defensible than claiming that the learner cannot write clearly in any context. The profile should open a useful teaching question without expanding one observation into a description of the whole person.
CHAPTER 4 OF 15 · Select a teaching priority
4. Separate the observed difficulty from its possible explanation
A sample can reveal a problem without settling its cause. If the learner gives an incomplete answer, they may have misunderstood the task, lacked a relevant expression, overlooked a condition or assumed that the listener already knew the missing information. The trainee needs to investigate before selecting a repair.
In Lina's fictional message, a missing old meeting time could be a task-interpretation issue. The instruction may not have made the reader's need clear. Alternatively, Lina may understand the requirement but be uncertain how to express the contrast. The visible omission alone does not distinguish those possibilities.
Ask a small clarifying question or use an appropriate further sample within the assignment arrangements. Can Lina explain what the recipient needs to know? Can she distinguish the two times when the language demand is reduced? The aim is to locate the difficulty, not to conduct an endless battery of tests.
The guide to prerequisite and method errors in mathematics has a different subject focus, but its diagnostic restraint is relevant: an incorrect outcome does not identify the point of failure by itself. Here the trainee must investigate the language task on its own terms, rather than import a mathematics classification as a CertTESOL rule.
Once a plausible learning need is identified, keep the uncertainty proportionate. “The evidence suggests…” can be appropriate where the samples are limited. It should introduce a specific interpretation that can inform teaching, not become a vague phrase that excuses a lesson choice unrelated to the learner's work.
CHAPTER 5 OF 15 · Select a teaching priority
5. Work through a message that preserves words but loses the relationship
The fictional task asks Lina to tell a colleague that a club meeting has moved from Tuesday to Thursday, while its starting time remains unchanged. Her message says that the meeting is on Thursday at the stated time. The individual facts are understandable, but the change from the earlier arrangement is not explicit.
The trainee first proposes a lesson on all uses of the past tense. That topic is much broader than the evidence currently requires. Before accepting it, ask what the recipient needs to do after reading the message. They must update a previous arrangement, not simply learn that a meeting exists.
A more focused objective could concern making a changed arrangement and an unchanged detail clear to a recipient. The teacher then identifies which language forms and organisation support that purpose. The communicative job gives the language analysis a reason; it does not remove the need for accurate language teaching.
| Original fictional evidence | Limited interpretation | Possible lesson focus |
|---|---|---|
| The new day is stated but the previous arrangement is not identified | The recipient may not know which entry to replace | Make the change explicit for a reader with the earlier timetable |
| The starting time is repeated without explaining that it stays the same | The reader may wonder whether the time also changed | Distinguish changed and unchanged information |
| The learner explains the contrast after a calendar prompt | The idea is available with support | Practise expressing it when that support is reduced |
The table is an original reasoning aid, not a reproduction of Trinity's assessment paperwork. The proposed focus still needs to be checked against the learner's wider evidence, the provider's brief and the trainee's teaching analysis. A plausible lesson idea becomes stronger when the trainee can explain why it is the right next priority for this learner.
CHAPTER 6 OF 15 · Select a teaching priority
6. Choose a priority without trying to teach everything
A profile may reveal several needs. The taught lesson has a limited opportunity to address them. Selecting a priority is therefore a reasoned choice, not a declaration that every other need is unimportant. Explain what is being addressed now and what belongs in a later recommendation.
Suppose Lina's message also contains two spelling difficulties and an uncertain article choice. If the immediate communicative problem is that the reader cannot distinguish the old and new arrangements, teaching all three areas at once may make the lesson less coherent. The trainee should consider which demand carries the main difficulty in this task.
That does not mean accuracy should be ignored. It means the trainee needs a defensible relationship between the objective, language analysis, activities and evaluation. Corrections that arise during a lesson can be handled appropriately without turning every noticed feature into an equally large objective.
State why the selected priority is useful to the learner. Connect it with the intended language use and the diagnostic evidence. A rationale based only on the trainee's preference is weaker than one that explains the learner's need and the realistic contribution of this lesson.
Then name a boundary. What will this lesson not establish about the learner's wider abilities? A focused lesson can support a meaningful next step without proving mastery of every kind of message or every context in which English is used. Keeping that boundary visible makes the later evaluation more truthful.
Compare a spoken need with a written need
Imagine a second fictional learner, Omar, who can write a clear timetable update when he has time to review it. In a short listening task, however, he records the original day after the speaker has corrected it. A trainee notices the familiar timetable topic and proposes the same written-message lesson used in Lina's case.
The topic is similar, but the evidence is different. Omar's difficulty concerns identifying the updated information in the supplied spoken sequence. A lesson focused only on composing a written contrast may leave that listening demand largely untouched. The trainee needs to explain how the proposed activity addresses the response actually observed.
Before deciding, examine the task conditions. Was the correction audible in the supplied material? Did Omar understand what information to record? Did he recognise the relevant language when it was examined afterwards? These questions help distinguish a language issue from a task misunderstanding or another limitation in the sample.
Suppose Omar understands the correction when the relevant part is revisited but does not reliably notice it in the original sequence. The trainee now has a more focused question about processing the spoken change. They should seek the tutor's guidance on appropriate analysis and teaching, rather than diagnose the entire listening system from one response.
Suppose instead that the task instruction was ambiguous about whether to record the original or final arrangement. The evidence cannot safely support the first diagnosis. Clarifying the task and obtaining an appropriate further response may be necessary before the trainee chooses the lesson priority.
These alternatives show why a learner profile should preserve the task as well as the answer. Without the original demand and conditions, a later reader may see only a wrong day and assume the same mechanism every time. The profile becomes more informative when the trainee can reconstruct the relationship between what was asked and what the learner did.
For a final comparison, return to Lina. She understands the spoken update but leaves the contrast unclear in her own message. Omar's lesson should not automatically become hers either. Similar content can reveal different learning needs because comprehension, information selection and production make different demands.
The trainee's rationale should therefore name more than the topic. It should identify the intended use, the observed performance and the priority that follows from their relationship. That reasoning makes a one-to-one lesson individual in a meaningful way, rather than simply attaching a learner's name to an activity prepared in advance.
CHAPTER 7 OF 15 · Plan an interpretable lesson
7. Write an objective that a later task can examine
An objective should identify an intended change in what the learner can understand or do. “Complete a worksheet” identifies an activity. “Make the revised day and unchanged starting time clear in a short message to a colleague” describes a performance that can be examined afterwards.
The difference affects lesson planning. If completion is the only target, the learner can finish every box while still leaving a recipient uncertain. If the target concerns a clear message, the trainee has to consider meaning, language and the reader's task together.
Avoid making the objective so large that the lesson cannot provide interpretable evidence. “Communicate confidently in English” may express a valuable long-term aim, but one lesson cannot establish it across situations. Narrow the immediate focus while retaining its connection to the learner's broader purpose.
Also avoid an objective whose success is guaranteed by the support supplied. If a learner copies a complete model with two nouns changed, the result may look clear without showing independent selection of the relevant language and information. The activity can be useful during teaching; a later check should establish more than successful copying.
For the taught lesson, follow the provider's actual requirements. The objective examples here are original teaching constructions, not compulsory wording. The useful test is whether the trainee can point to a later learner response and explain how it bears on the objective they selected.
CHAPTER 8 OF 15 · Plan an interpretable lesson
8. Give each activity a job in the lesson
A sequence of engaging activities is not automatically a coherent lesson. Ask what each stage helps the learner notice, understand, practise or use. If the connection with the objective is unclear, the activity may need adapting, moving or removing.
In Lina's fictional lesson sketch, the first task compares two short original messages. One makes the old and new arrangements clear; the other leaves the change implicit. Lina identifies what the recipient could and could not update from each. This gives the language work a communicative purpose before the trainee examines useful forms.
A supported practice can then help Lina express a change accurately. The support might include relevant information categories or a partial model. Record what was supplied. The trainee should not later describe the supported response as evidence that Lina independently selected every part of the message.
The final activity can use a fresh fictional arrangement with a different changed detail. Lina now has to decide what the recipient needs to know and construct a suitable message. The task remains close enough to the objective to be interpretable, while changing enough to reduce reliance on the earlier wording.
This is a sketch of pedagogic reasoning, not a complete assessed lesson plan. The trainee still needs appropriate language analysis, materials, timing, interaction and provider guidance. The contribution of the sketch is to make every activity answer a question about learning instead of merely filling an available period.
CHAPTER 9 OF 15 · Plan an interpretable lesson
9. Notice when the teacher's support is carrying the response
Support is part of teaching. The problem arises when its contribution disappears from the account of the learner's performance. A correct response following several targeted hints establishes something different from a response in which the learner recognised and selected the relevant information independently.
Suppose the trainee asks Lina, “You need to mention the old day, don't you?” Lina adds it. The intervention may help her notice the missing information, but the trainee has supplied the selection. A later task should reveal whether Lina now notices that need without the same prompt.
The existing tutor handbook on follow-up questions examines that moment-to-moment teaching judgement in its own setting. Its relevant connection is to distinguish revealing the learner's thinking from supplying the missing route. It is not a Trinity assessment policy.
A useful lesson evaluation can identify the support, the learner's response and the later attempt. This makes progress more precise. The learner may have moved from not noticing the contrast to using it after a broad reminder, even if full independence has not yet been established.
Avoid turning the removal of support into a sudden test of everything at once. If the language, task, format and context all become much harder, a difficulty may be hard to interpret. Choose a change that helps answer the learning question raised by the original profile.
CHAPTER 10 OF 15 · Evaluate and transfer
10. Evaluate what the learner did rather than how the lesson felt
A lesson can feel friendly and well organised while leaving the intended learning uncertain. Another can reveal a difficulty that makes the next teaching decision much clearer. Evaluation should consider the learner's actual responses in relation to the objective, rather than rely only on the trainee's impression of a successful session.
After Lina's fictional lesson, the trainee notes that she completed a supported message and a later fresh task. The evaluation needs to distinguish them. Which information did Lina select? How accurately did she express it? What help was provided? Did the final response allow the intended recipient to understand the revised arrangement?
Suppose the final message clearly states the changed day but omits the unchanged starting time. This is a mixed result. It supports recognition of one demand while leaving another uncertain. Reporting that mixture gives the next recommendation a better basis than declaring either complete success or complete failure.
The trainee should also examine the task itself. Did the final prompt make it clear that the recipient held the earlier timetable? If not, the omission may not establish the interpretation the trainee first proposed. Evidence of learning depends partly on what opportunity the task actually gave the learner to demonstrate it.
An honest evaluation can revise the original diagnosis. Perhaps Lina understood the time contrast but needed a clearer reader context. The lesson has then taught the trainee something important about assessment design as well as language teaching. Preserve that finding rather than rewrite the account to make the first plan appear correct from the beginning.
Follow one revised diagnosis through another sample
Imagine the trainee adds a short clarification task. Lina is explicitly told that the recipient still has the old timetable. She explains the changed day and unchanged time clearly. The new evidence suggests that the earlier omission should not be treated as proof of an inability to express the relationship.
The next question is whether Lina can identify that reader need when it is less explicitly highlighted. A later sample can provide the old timetable as part of the situation without naming every required detail. If Lina selects the relevant contrast, the trainee has stronger evidence about independent task interpretation.
If she does not, the lesson recommendation may concern reading the communicative situation and selecting necessary information alongside language practice. That differs from a plan consisting only of more sentence-level grammar exercises. The profile becomes more useful as its claims become more precise.
This small cycle also prevents a common overcorrection. Discovering that one omission was partly task-related does not prove that every language difficulty is a task-design problem. Keep the other samples available. A revised interpretation should fit the evidence rather than replace one sweeping conclusion with another.
CHAPTER 11 OF 15 · Evaluate and transfer
11. Connect recommendations with the remaining evidence
Recommendations should continue the reasoning rather than introduce an unrelated list of attractive topics. For each proposed next area, identify the learner use or observed need that justifies it. This lets the reader understand why the plan belongs to this learner.
The public syllabus includes further-study recommendations linked with the analysis. Use the provider's current brief for the required scope and format. The teaching examples here do not replace that requirement with a shorter personal checklist or a different invented assessment framework.
An immediate next recommendation might address Lina's independent selection of information for a recipient. Another may concern a separate need supported by listening or spoken evidence. Avoid treating the success of one written message as proof that the equivalent demand is secure in every skill.
Time categories also need clarity. The public Unit 3 syllabus describes its one-to-one lesson separately from the observed and assessed teaching-practice hours. Keep the applicable course categories intact. Completing one learning activity should not be recorded as a different formal requirement simply because both involve teaching.
The existing CELTA guide to planning work around assessed teaching hours explains another qualification's workload structure. It can help readers notice why categories matter, while CELTA and CertTESOL requirements remain separate. This article's job is the connection between Unit 3 evidence and a teaching choice.
CHAPTER 12 OF 15 · Evaluate and transfer
12. Change the learner's purpose and reconsider the lesson
Take the original timetable case and change the intended use. The learner no longer needs to write an update; they need to understand a spoken change in a group conversation. The earlier written-message lesson may contribute something, but it does not automatically address the new demand. Reconsider which evidence is needed.
Now keep the communicative purpose but change the diagnostic finding. The learner makes the old and new arrangements clear while repeatedly confusing the actual dates. The next teaching question may concern comprehension or expression of the time information, rather than the organisation of a message. The plan should change with the evidence.
Next, change the support. A learner succeeds only while looking at a fully completed example. Can the trainee describe that success accurately and plan a suitable next attempt? The polished output should not conceal that the example supplied the information selection and much of the language.
Finally, change the result after teaching. The learner's later response differs from the trainee's expectation. Ask what the response establishes, which parts remain uncertain and whether the task gave a fair opportunity to demonstrate the objective. Evaluation should be allowed to alter the next recommendation.
These original cases test the trainee's judgement, not an official mark scheme. A useful response identifies the changed fact and explains its consequence for evidence, priority or lesson design. That is the transferable skill: using a profile to make the next teaching decision rather than attaching the same lesson to every learner.
CHAPTER 13 OF 15 · Take the next teaching step
13. Give the trainee, learner and tutor workable roles
The trainee gathers and analyses evidence, selects a defensible priority and explains the lesson's rationale. They also retain responsibility for checking their own language analysis. A learner's sample can reveal a teaching opportunity without guaranteeing that the trainee's first explanation of the language is accurate.
The learner contributes goals, experience and authentic responses within the agreed course arrangements. They should not be reduced to a list of deficits. Strengths matter because they show what the next lesson can build on and prevent secure areas from being retaught simply because a generic plan includes them.
The tutor clarifies the assignment, helps the trainee interpret evidence and assesses the work through the validated provider's process. A trainee should bring a specific uncertainty: perhaps the sample supports two diagnoses, or a proposed objective is too broad. That is easier to examine than a request to approve an entire plan without seeing the reasoning.
Supporters outside the course can help with time and organisation. They should not write the assessed profile or supply invented learner data to complete a missing section. Fictional examples are appropriate here because this is a teaching article; they are not substitutes for the evidence required in the trainee's actual assignment.
Keep personal learner material within the course's actual consent, recording and information-handling arrangements. This article needs no real learner details and provides no alternative retention policy. The educational focus is a transparent connection between the evidence collected appropriately and the teaching decision made from it.
A trainee should also distinguish uncertainty in the learner's performance from uncertainty in their own analysis. If the trainee is unsure why a form is appropriate, that question needs reference work and tutor guidance before teaching. It should not be recorded as another learner deficit. Bringing the original sample, the proposed interpretation and the unresolved language point to a tutorial makes the discussion more useful. The tutor can examine the reasoning and help the trainee correct an explanation before it shapes a lesson or an assessed account.
The Unknown Language journal guide examines the trainee's own experience as a beginner. That perspective can sharpen attention to support and uncertainty, while the learner profile still needs evidence from the actual learner. Personal insight should inform the questions you ask rather than replace their answers.
CHAPTER 14 OF 15 · Take the next teaching step
14. Questions trainees commonly ask
Is the longest error list the best profile?
Length alone does not make the analysis useful. Explain what the evidence reveals, which needs matter to the learner's intended use and why a particular priority is appropriate. A list that never changes the lesson plan has not yet become a teaching rationale.
Must I teach every difficulty in one lesson?
The lesson has a defined scope. Select a defensible priority and keep the remaining needs available for appropriate recommendations. Trying to address everything equally can make the objective and evaluation difficult to interpret. Use the actual provider brief for required coverage.
Can an interview show all four skills?
Different evidence sources reveal different performances. A conversation does not replace every reading or writing sample. The public syllabus brings several sources into the profile; follow the current assignment instructions and preserve what each source can actually show.
Does a correct supported response establish independence?
It establishes performance with that support. The support may have been exactly what the learner needed during teaching. A later appropriate task helps reveal whether the learner can now recognise and select the relevant information or language without the same prompt.
What if the lesson changes my diagnosis?
Record the new evidence and explain the revision. That can be a useful professional learning outcome. Do not force the final account to confirm the first interpretation when the learner's responses or the task conditions suggest a more accurate explanation.
Can I submit these fictional samples?
No. They are original illustrations for understanding the reasoning. Your assessed work must use the actual evidence and arrangements required by your provider. Copying a case would remove the learner-specific analysis that the task is intended to develop.
Will this profile establish that I can teach every learner?
No single profile establishes that claim. It provides an opportunity to develop and demonstrate particular initial-training skills. Continue to use tutor guidance and later professional learning rather than treat one completed assignment as a universal teaching method.
CHAPTER 15 OF 15 · Take the next teaching step
15. Sources and the next teaching decision
The primary sources, checked on 23 October 2026, are Trinity's CertTESOL qualification information and the publicly available CertTESOL syllabus, including Unit 3. Trinity's validation requirements also describe the provider's role in organising this unit. Consult your validated provider's current instructions for the actual assignment evidence, format and assessment arrangements.
The named learner, messages, table and lesson sequence are original fictional teaching material. The suggestions for selecting a priority and examining a later response are educational applications, not extra Trinity rules or promises about measured outcomes. They do not replace a complete lesson plan, language analysis or tutor assessment.
For a next review, choose one proposed lesson objective. Trace it back to the learner's intended use and a specific piece of evidence. Then identify what response after teaching would support your evaluation and what uncertainty it would leave.
A useful profile makes the next lesson less arbitrary. The trainee can explain why this learner, with this evidence, should meet this task next—and can revise that decision when the learning reveals something new.
