Many Junior College essays contain evaluation words without evaluation standards. A policy is called “effective”, a system “fair”, a technology “successful”, a reform “better”. The sentence sounds analytical, but the reader is left with a basic question: compared with what?
The broader eduKateSG guide, Vocabulary for Junior College (JC1–JC2): Adult Thinking, Professional Writing, treats vocabulary as a means of making judgement precise. Benchmarks, baselines, criteria and thresholds are four of the most useful tools for doing that.
Evaluation needs a reference point
“This policy reduced unemployment” is incomplete if unemployment was already falling before the policy began. “This school performs well” means little without knowing the intake, comparison group or intended outcome. “This technology is safer” requires a benchmark.
Good comparative vocabulary makes the reference point visible.
Benchmark: the standard used for comparison
A benchmark is a reference standard against which performance is judged. It may be another country, an earlier period, an industry standard, a target or the best available alternative.
- relative to the benchmark
- compared with the prevailing standard
- outperforms the alternative
- falls short of the target
- meets the minimum standard
The choice of benchmark matters. A weak competitor can make ordinary performance look excellent.
Baseline: the starting condition
A baseline tells us what conditions looked like before an intervention or change. Without a baseline, improvement is difficult to interpret.
If student scores rise from 40 to 60 after a programme, that may be substantial. But if a comparable group rose from 40 to 65 without the programme, the interpretation changes. The baseline is not the entire analysis, but it prevents a before-and-after story from becoming automatic proof.
Criterion: the dimension being judged
A criterion answers: according to what standard is this good or bad?
- Effectiveness: does it achieve the goal?
- Efficiency: at what resource cost?
- Equity: how are costs and benefits distributed?
- Legitimacy: is the authority or process defensible?
- Sustainability: can it continue over time?
- Resilience: can it withstand disruption?
A policy can score well on one criterion and poorly on another. Mature judgement identifies which criterion matters most in the context.
Threshold: the point at which judgement changes
A threshold is the level at which a condition becomes sufficient to trigger a different response. It is especially useful in policy and ethical arguments.
When does misinformation become harmful enough to justify intervention? How severe must a security threat be before intrusive surveillance becomes proportionate? At what point does inequality threaten social mobility or cohesion?
Threshold vocabulary makes the difficult boundary explicit instead of pretending every case is identical.
The “better than what?” test
Whenever an essay uses better, worse, more successful, fairer or more effective, add the silent question: better than what?
A policy should often be compared not with perfection but with feasible alternatives. This is crucial. Many arguments reject an imperfect intervention by comparing it with an imaginary solution that has no cost or downside.
Adult judgement compares real options.
Worked example: public transport
Claim: “Public transport is better than private cars.”
The sentence needs criteria. Better for congestion? Carbon emissions? Door-to-door travel time? Accessibility? Comfort? Cost to the user?
High-capacity public transport can outperform private cars on land use and emissions in dense cities, although the advantage is smaller for journeys poorly served by the network or for users with particular accessibility needs.
The judgement becomes more useful because the criteria and conditions are visible.
Worked example: examinations
“Exams are an effective assessment method” should trigger the same questions. Effective at what? Ranking students? Sampling knowledge? Testing performance under time? Predicting later success?
A stronger paragraph may conclude that examinations are effective for some forms of standardised comparison but insufficient as the sole measure of complex abilities. The evaluation is now criterion-specific.
Beware moving benchmarks
Writers sometimes change the standard mid-argument. A technology is first praised because it is cheaper, then defended because it is faster, then judged successful because users like it. Each may be relevant, but the criteria have shifted.
Strong writing tells the reader which criterion is primary and why.

Distribution matters, not just averages
A policy can improve the average outcome while harming a particular group. A national statistic may improve while regional disparities widen. Comparative judgement therefore needs words such as average, median, distribution, disproportionately and unevenly.
Asking “who benefits?” is often as important as asking “does it work?”
A four-step evaluation frame
- Name the objective.
- Select the relevant criterion.
- Choose a defensible benchmark or baseline.
- State the threshold at which your judgement changes.
This turns vague evaluation into something the reader can inspect.
Professional writing uses the same discipline
A business proposal that claims “strong performance” should specify whether performance means revenue, profitability, retention, reliability or risk-adjusted return. A policy brief should identify the baseline and realistic alternatives. A recommendation should state the criterion that matters most.
Without those reference points, evaluation becomes rhetoric.
What mastery looks like
A strong JC writer can recognise an undefined comparison, choose a relevant benchmark, distinguish baseline from target, evaluate across more than one criterion and explain why one standard deserves greater weight.
That is what turns “I think this is better” into comparative judgement.
Comparative Judgement Lab: Choose the Right Reference Point
Evaluation becomes substantially stronger when students distinguish four different reference points: the baseline we started from, the benchmark we compare against, the target we hope to reach, and the counterfactual describing what would likely have happened without the intervention.
Baseline, Benchmark, Target, Counterfactual
- Baseline: the initial condition.
- Benchmark: a relevant comparison standard.
- Target: the desired outcome.
- Counterfactual: the plausible alternative world without the action.
A programme can improve from its baseline, miss its target and still outperform the counterfactual. Those are three different judgements. Mature writing keeps them separate.
Worked Example: Education Intervention
Suppose results rise after an intervention. The baseline comparison says performance improved. A benchmark comparison may show similar schools improved even more. The target may still be unmet. The counterfactual may suggest results would otherwise have declined. One dataset can therefore support several different evaluations depending on the reference point.
Choosing Criteria Before Judging
For a transport policy, possible criteria include journey time, reliability, affordability, accessibility, emissions and land use. For an education policy: attainment, equity, validity, wellbeing and administrative burden. The writer should decide which criteria are relevant before declaring the policy successful or unsuccessful.
Weighting Criteria
Not every criterion deserves equal weight. A safety intervention might accept moderate inconvenience to prevent severe harm. A low-risk policy may prioritise cost and convenience. Vocabulary such as decisive consideration, secondary criterion, outweighs and carries greater weight lets the writer explain the hierarchy.
Thresholds and Sensitivity
Ask what amount of change would alter your judgement. If a policy is worthwhile only when it reduces harm by a large margin, say so. Then ask whether a small change in assumptions would reverse the conclusion. A judgement that collapses under tiny changes is fragile; one that survives reasonable variation is more robust.
The Feasible-Alternative Rule
Do not compare a real policy with perfection. Compare it with realistic alternatives, including doing nothing. “This solution has flaws” is not enough if every feasible alternative is worse on the criteria that matter most.
Comparative Writing Drill
- Choose a policy or technology.
- Name its baseline and one credible benchmark.
- Select three criteria.
- Rank the criteria by importance.
- Compare against a feasible alternative.
- State the threshold at which your preference changes.
Final Evaluation Check
- Have I defined “better”?
- Is my benchmark fair?
- Am I comparing like with like?
- Have I considered distribution as well as averages?
- Would another reasonable criterion produce a different result?
Comparative judgement is mature when the reader can see not only the conclusion, but the standard that produced it and the condition under which it would change.
