Make responsibility visible across people, activities and dates without turning delegation into a vague list of names
A research study delegation log records who is authorised by the investigator to perform which trial-related activities and during what period. It supports oversight, training and reconstruction of conduct. English matters because a broad phrase such as “study procedures” can hide activities that require different qualifications, approvals, access and supervision.
Choose the route closest to your task, or read straight through for the complete system.
People search for delegation of authority logs, clinical trial responsibility logs and study staff signature logs because one table has to connect names, tasks, training and time. A weak log proves only that people existed. A useful log shows the operational authority that applied on the day an activity occurred.
The log should match the protocol, site workflow, approvals and actual qualifications. It should distinguish delegation from employment, system access, training attendance and authorship. These records support one another but do not substitute for one another.
Entries should be made prospectively where required and maintained as responsibilities change. A late, backdated or over-broad entry can obscure who actually performed an activity and whether they were prepared. Corrections should remain traceable.
This article is educational guidance checked on 11 October 2026. Use the sponsor’s and institution’s current template and procedure. Professional licensing, PI-only decisions and local approval conditions may limit what can be delegated.
Did You Know? Singapore HSA’s current template page describes the delegation log as the record of persons or parties to whom the PI has delegated trial-related activities, and pairs it with a training log designed to show that site staff are appropriately qualified for those tasks. ICH E6(R3) also says delegated activities should be documented appropriately while the investigator retains overall responsibility for trial activities under their oversight.

How to build this kind of English before the job title arrives
Back to contentsStudents do not need professional authority to practise the underlying language. They can learn to define scope, annotate conditions, compare versions, rebuild a timeline, match a number to its unit and explain uncertainty without embarrassment. Parents can ask calm questions: What decision is this document supporting? Which sentence carries the strongest claim? What would make that claim false? Which source would you open next?
Use a three-pass routine. First, map the document: title, owner, audience, date, sections and decision. Second, trace one claim from source to conclusion. Third, explain the limit and next action. This routine strengthens comprehension, science, mathematics, humanities and workplace readiness because it turns English into an evidence tool.
A student should never imitate professional authority. The useful goal is to recognise when a text needs a qualified reviewer, current rule or official decision. Knowing when to pause is part of literacy.

Each case turns a fluent shortcut into an evidence and responsibility problem. Explain what changed, whose choice or duty is affected and why the repaired version is safer.
Case 1: Start from the real activity map
The site identifies prescreening, consent discussion, eligibility confirmation and enrolment as separate decisions. The learner identifies the tempting shortcut, checks the controlling evidence, explains the consequence for the affected person and records the repair in complete sentences.
Record the governing source, approved version, people affected, decision authority, evidence and uncertainty. Then write the smallest conclusion that remains accurate if one rule, fact, role, date or permission changes.
Case 2: Match each person to qualifications and role
A trained phlebotomist is delegated sampling only after the site confirms current credentials and study procedure training. The learner identifies the tempting shortcut, checks the controlling evidence, explains the consequence for the affected person and records the repair in complete sentences.
Record the governing source, approved version, people affected, decision authority, evidence and uncertainty. Then write the smallest conclusion that remains accurate if one rule, fact, role, date or permission changes.
Case 3: Keep system access separate but aligned
A coordinator’s randomisation access ends on the same authorised date as the delegated duty. The learner identifies the tempting shortcut, checks the controlling evidence, explains the consequence for the affected person and records the repair in complete sentences.
Record the governing source, approved version, people affected, decision authority, evidence and uncertainty. Then write the smallest conclusion that remains accurate if one rule, fact, role, date or permission changes.
Case 4: Review and archive as an essential record
At close-out, every active entry has an end status and outstanding access is checked. The learner identifies the tempting shortcut, checks the controlling evidence, explains the consequence for the affected person and records the repair in complete sentences.
Record the governing source, approved version, people affected, decision authority, evidence and uncertainty. Then write the smallest conclusion that remains accurate if one rule, fact, role, date or permission changes.
A parent, tutor, supervisor or peer may ask for the source and logic, but the learner should make the final evidence note in their own words.
Use the live rule and controlled study evidence. Preserve source wording, interpretation, participant consequence, decision, authority and version separately.
Define the activities
Turn protocol work into specific delegable tasks. Use Chapters 1–2 to build a dated evidence note and authorised decision.
Record the governing source, approved version, people affected, decision authority, evidence and uncertainty. Then write the smallest conclusion that remains accurate if one rule, fact, role, date or permission changes.
Verify the people
Match qualifications, training, role and access. Use Chapters 3–4 to build a dated evidence note and authorised decision.
Record the governing source, approved version, people affected, decision authority, evidence and uncertainty. Then write the smallest conclusion that remains accurate if one rule, fact, role, date or permission changes.
Control the dates
Show when authority began, changed and ended. Use Chapters 5–6 to build a dated evidence note and authorised decision.
Record the governing source, approved version, people affected, decision authority, evidence and uncertainty. Then write the smallest conclusion that remains accurate if one rule, fact, role, date or permission changes.
Keep oversight visible
Separate delegation from retained responsibility. Use Chapters 7–8 to build a dated evidence note and authorised decision.
Record the governing source, approved version, people affected, decision authority, evidence and uncertainty. Then write the smallest conclusion that remains accurate if one rule, fact, role, date or permission changes.
Reconcile the record
Align signatures, systems, source and staff changes. Use Chapters 9–10 to build a dated evidence note and authorised decision.
Record the governing source, approved version, people affected, decision authority, evidence and uncertainty. Then write the smallest conclusion that remains accurate if one rule, fact, role, date or permission changes.
Finish with three sentences: what is supported, what remains uncertain and what evidence or authorised action comes next.
The evidence should remain stable even when emphasis, detail and next action change with the reader.
Participant lens
Qualified people should perform authorised tasks.
Record the governing source, approved version, people affected, decision authority, evidence and uncertainty. Then write the smallest conclusion that remains accurate if one rule, fact, role, date or permission changes.
PI lens
Delegation does not remove oversight responsibility.
Record the governing source, approved version, people affected, decision authority, evidence and uncertainty. Then write the smallest conclusion that remains accurate if one rule, fact, role, date or permission changes.
Staff lens
Task boundaries, support and escalation should be clear.
Record the governing source, approved version, people affected, decision authority, evidence and uncertainty. Then write the smallest conclusion that remains accurate if one rule, fact, role, date or permission changes.
Monitor lens
Authority should match real conduct and dates.
Record the governing source, approved version, people affected, decision authority, evidence and uncertainty. Then write the smallest conclusion that remains accurate if one rule, fact, role, date or permission changes.
Security lens
Access should align with current delegated need.
Record the governing source, approved version, people affected, decision authority, evidence and uncertainty. Then write the smallest conclusion that remains accurate if one rule, fact, role, date or permission changes.
Adaptation helps only when the short version preserves identity, source, status, rights, evidence, uncertainty and boundary.
These exercises are deliberately slower than real drafting. Rebuild the decision chain, then compress it without losing the condition that controls the outcome.
Use specific verbs and bounded task labels
“Clinical duties” or “study procedures” cannot show what was authorised. Write observable activities with scope, conditions and decision boundary. Example: “Collect protocol blood samples” is separate from “assess clinical significance of results.” Before accepting the conclusion, test the named source, audience, scope, date, authority and exception against the controlled record.
Record the governing source, approved version, people affected, decision authority, evidence and uncertainty. Then write the smallest conclusion that remains accurate if one rule, fact, role, date or permission changes.
Separate delegation from accountability
Assignment of work does not remove the investigator’s responsibility for oversight. Record the delegated activity, responsible PI, supervision or escalation route and review evidence. Example: A coordinator schedules visits, while the PI retains medical and eligibility decisions required by the protocol. Before accepting the conclusion, test the named source, audience, scope, date, authority and exception against the controlled record.
Record the governing source, approved version, people affected, decision authority, evidence and uncertainty. Then write the smallest conclusion that remains accurate if one rule, fact, role, date or permission changes.
Link training to the delegated activity
A general GCP certificate may not prepare someone for a particular device, system or participant group. Use a training matrix that connects person, task, document version, trainer, date, assessment and refresher need. Example: A data manager completes protocol and system training before receiving entry duties. Before accepting the conclusion, test the named source, audience, scope, date, authority and exception against the controlled record.
Record the governing source, approved version, people affected, decision authority, evidence and uncertainty. Then write the smallest conclusion that remains accurate if one rule, fact, role, date or permission changes.
Control signatures and initials
Signature records help attribute entries but can create privacy and fraud risks. Use the approved signature method, protect specimens, explain electronic signatures and preserve changes. Example: The signature sheet is combined with the delegation record only where the process permits it. Before accepting the conclusion, test the named source, audience, scope, date, authority and exception against the controlled record.
Record the governing source, approved version, people affected, decision authority, evidence and uncertainty. Then write the smallest conclusion that remains accurate if one rule, fact, role, date or permission changes.
Reconcile the log with actual conduct
A neat log can still conflict with consent forms, source notes, system audit trails and pharmacy records. Sample real activities and compare performer, date, task, training and authority. Example: A consent form signed by a person absent from the log triggers investigation and proportionate action. Before accepting the conclusion, test the named source, audience, scope, date, authority and exception against the controlled record.
Record the governing source, approved version, people affected, decision authority, evidence and uncertainty. Then write the smallest conclusion that remains accurate if one rule, fact, role, date or permission changes.
Repeat the drill after a source, participant need, person, risk, permission, version or timetable changes. The revised note should show exactly why the earlier conclusion was retained or replaced.
A polished line can conceal a missing rule, identifier, comparison, version, right, permission or condition. Run these tests before relying on fluency.
Activity test
Replace broad task labels with observable actions and decision boundaries.
Record the governing source, approved version, people affected, decision authority, evidence and uncertainty. Then write the smallest conclusion that remains accurate if one rule, fact, role, date or permission changes.
Qualification test
Match each task to licence, experience, protocol training, procedure training and authorisation.
Record the governing source, approved version, people affected, decision authority, evidence and uncertainty. Then write the smallest conclusion that remains accurate if one rule, fact, role, date or permission changes.
Date test
Check that delegation, signatures, system access and actual conduct align on the day.
Record the governing source, approved version, people affected, decision authority, evidence and uncertainty. Then write the smallest conclusion that remains accurate if one rule, fact, role, date or permission changes.
Oversight test
Show retained PI responsibility, escalation, review and reconciliation.
Record the governing source, approved version, people affected, decision authority, evidence and uncertainty. Then write the smallest conclusion that remains accurate if one rule, fact, role, date or permission changes.
Keep the failed version beside the repair. The contrast shows exactly where language outran the approved record.
Answer each prompt in a complete sentence tied to a current instruction, approved version, dated source, observation or authorised clarification. Write “unknown” where the record does not support an answer.
- Map protocol? Record the evidence and the conclusion it permits.
- Map site process? Record the evidence and the conclusion it permits.

- Name oversight? Record the evidence and the conclusion it permits.
Independent-reader test
Give the working note to a careful reader who was not present. Ask them to identify the study, audience, source, approved version, reasoning, authority, uncertainty and next action without extra explanation. Repair a missing link rather than adding decorative formality.
Change test
Imagine that the protocol, participant need, investigator, platform or approval condition changes tomorrow. Mark every sentence that would need revision. This makes cycle-sensitive claims visible and prevents an old note from controlling a new decision.
Decision log
Keep the instruction consulted, date, choice, responsible person and reason. Add rejected alternatives when they may be revisited. A collaborator or future student can then distinguish a documented requirement from a stylistic preference.
Parent or mentor conversation
Ask three calm questions: Which words carry the strongest claim? What evidence controls those words? What condition would make you revise the conclusion? The goal is accountable curiosity, not supplying a ready-made answer.
What is a research delegation log?
It records which qualified persons the investigator has authorised to perform specified study activities during defined periods.
Does delegation transfer PI responsibility?
No. The investigator retains overall responsibility for activities under their oversight.
Is training the same as delegation?
No. Training supports readiness; the authorised delegation and its effective date are separate evidence.
Can one broad task cover everything?
Only if the approved process genuinely defines it that way without hiding different qualifications or decisions.
Can an entry be backdated?
Do not create retrospective authority. Follow the correction and noncompliance process for a late or missing record.
When should access be removed?
When the authorised role no longer requires it, according to the controlled process and documented date.
