Timed Versus Untimed Skills Tests: How Employers Can Choose Fairly

A company wants to hire an accounts assistant. It prepares a test containing calculations, invoice checks and short workplace scenarios. One manager wants candidates to finish quickly because the team works under deadlines. Another argues that the company needs accurate work, not people who rush through questions.

Both managers are raising useful points. But neither has yet answered the most important question: Does speed matter for the work being assessed?

That question should guide the decision between a timed and an untimed skills test. A time limit can help an employer understand how someone works under reasonable pressure. It can also hide the very ability the employer wants to measure if the limit is too strict or unrelated to the job.

This guide explains the difference, gives realistic examples and provides a decision process that employers can use without specialist testing knowledge.

What is a timed skills test?

A timed skills test gives candidates a fixed period to complete questions or tasks. For example, candidates might have 45 minutes to answer 40 questions. When the time expires, the assessment ends or stops accepting answers, according to the stated rules.

Timed tests may be useful where working at a reasonable pace is genuinely important. A customer service role may require staff to interpret information and respond promptly. A bookkeeping role may involve completing routine checks within a normal working period.

However, the mere existence of deadlines at work does not prove that every test for that job should be fast. Employees often use software, reference materials, colleagues and review processes that are unavailable in a test. The assessment should reflect the skill the employer actually needs.

What is an untimed skills test?

An untimed skills test does not impose a fixed completion deadline once the candidate starts, or allows enough time that speed is not intended to influence the result. Employers may still set an administrative submission date, such as asking candidates to complete an exercise within three days.

Untimed tests are often suitable when the employer mainly wants to assess reasoning, accuracy, judgement or the quality of a finished piece of work. Examples include reviewing a policy, finding errors in a financial schedule or writing a carefully considered response to a client complaint.

Untimed does not mean uncontrolled. Employers can still provide instructions, limit outside assistance, use an agreed task scope and document how results will be reviewed.

The main difference

Neither approach is automatically better. The best choice depends on the purpose of the assessment and the evidence supporting its use.

Start with the job, not the test platform

Employers sometimes choose timed tests because a platform includes a timer. Others choose untimed tests because they want candidates to feel comfortable. Both decisions put the test format ahead of the job.

Instead, ask what successful employees must actually do.

For an accounts assistant, the employer might identify three requirements:

1. Check transactions accurately.
2. Notice missing information or unusual entries.
3. Complete routine work within reasonable business deadlines.

The first two requirements concern accuracy and judgement. The third involves pace. A well-designed assessment may therefore include an untimed or generously timed accuracy task and a separate, appropriately timed routine task.

This is often better than using one strict timer for every question.

Three questions before choosing a time limit

What is the main skill? If the test measures careful analysis, a strict timer may change what the result means. Candidates might be rewarded for guessing quickly rather than thinking correctly.

Does the job genuinely require speed? A receptionist answering routine enquiries may need to respond promptly. A compliance officer reviewing an unusual case may need to pause, investigate and document the reasoning.

What conditions exist in real work? If employees normally use calculators, spreadsheets, reference documents or accessibility tools, consider whether the test should allow them too.

Worked example: Two candidates, two different strengths

Imagine an employer gives a fictional 20-question invoice-checking test.

Candidate A is more accurate. Candidate B finishes faster. Which candidate performed better?

The answer depends on the job requirement. If errors could cause serious financial loss, the employer may place greater importance on accuracy. If the task involves high-volume routine checks and an acceptable error rate has been established, pace may also matter.

The employer should not invent a combined score after seeing these results. It should decide in advance whether accuracy, speed or both are important, and explain the scoring approach to candidates.

For example, a policy might require a minimum accuracy level before pace is considered. But the particular minimum must be supported by job requirements and appropriate review; the figures above do not establish a universal pass mark.

When timed assessments may be appropriate

Routine work with genuine time demands

Some jobs involve repeated tasks that must be completed promptly. A timed exercise may help an employer see whether a candidate can maintain accuracy at a reasonable pace.

The key phrase is reasonable pace. A test should not require unusually rapid performance merely to create competition.

Situations requiring timely decisions

A supervisor may need to prioritise several urgent requests. A short, timed scenario can explore how candidates identify what needs attention first. But a written scenario is still only a sample of behaviour, not proof of how someone will perform in every real emergency.

Large-scale screening with a justified design

Employers sometimes use time limits to administer tests consistently to many candidates. Consistent scheduling is an operational benefit, but it is not enough on its own to justify a strict deadline. The limit should remain appropriate for the skills and candidate population.

When untimed assessments may be more suitable

Work where accuracy matters more than speed

A tax analyst reviewing an unfamiliar issue may need to read legislation, check calculations and prepare a reasoned explanation. An extremely short test could reward superficial answers.

Complex problem-solving

A case study that asks candidates to compare options, explain trade-offs and recommend a decision may benefit from enough time for reflection. Employers can judge the reasoning rather than how quickly the candidate types.

Learning and development

An assessment used to identify training needs should often allow people to demonstrate what they know without unnecessary pressure. If the purpose is development rather than selection, speed may add little useful information.

Early-stage testing of new questions

When an employer is checking whether instructions and questions are understandable, an untimed trial can reveal how candidates approach the tasks. Time data can still be recorded for research and improvement without automatically affecting scores.

A practical option: Use different timing rules for different sections

A test does not have to be entirely timed or entirely untimed. Consider a fictional assessment for a customer service team leader:

These are design options, not validated time recommendations. Employers should review each section against the role and test it with an appropriate group before using the results for important decisions.

A standard session is not a universal timing rule

A 40-question, 45-minute session is one delivery configuration, not evidence that every role or assessment category should be timed identically. Employers should consider the capability being measured and any applicable accommodations. Detailed timing evaluation belongs in the separate Time Limits in Online Assessments guide.

Decide the format before calibrating a timer

First decide whether speed is genuinely part of the job-relevant construct. Choose timed, untimed or mixed-section delivery accordingly, and record the reason and any accessibility implications. Only after that format decision should the team pilot specific durations, inspect deadline effects and document adjustments. Detailed timer calibration belongs in the companion guide on time limits in online assessments.

First determine whether speed is a genuine part of the target job. If it is, a timed section may be defensible; if it is not, avoid introducing time pressure merely for administration convenience. Once the format decision is documented, consult Time Limits in Online Assessments: When Speed Matters for trial procedures, timing calculations, technical interruptions and accommodations. This article focuses on the choice between timed and untimed evidence.

Fairness and accessibility matter in both formats

Timed assessments can create additional barriers for some candidates, including people who use assistive technology or require an approved adjustment. Employers should provide a clear way to request reasonable arrangements and assess requests individually under applicable requirements.

Untimed tests are not automatically accessible. A candidate may still face an unreadable interface, incompatible screen-reader controls, confusing instructions or a task that cannot be completed on their available device.

Fairness requires attention to the whole experience: invitation, instructions, technology, assessment content, scoring and the handling of unexpected problems.

Employers should not ask candidates to disclose unnecessary medical information to ordinary hiring managers. Adjustment decisions and related records should be handled carefully and confidentially.

Remote testing can make time pressure less meaningful

Two candidates may have similar skills but very different internet connections. One may use a desktop computer with stable power. Another may rely on a mobile device and intermittent connectivity.

If the timer continues during a technical interruption, the result may partly reflect the candidate's environment rather than ability.

Before launching a timed remote test, employers should decide:

• What happens if a connection drops?
• Can a candidate resume, and under what conditions?
• When is a retest appropriate?
• How will technical problems be recorded?
• Who can approve an exception?
• How will candidates receive support without revealing confidential answers?

Apply the same documented rules to comparable cases while allowing justified individual adjustments.

Avoid five common mistakes

Mistake 1: Assuming faster always means better. Fast responses can reflect confidence, guessing, familiarity with the test or genuine skill. Time alone does not explain which.

Mistake 2: Giving every question the same allowance. Questions vary in reading demands and complexity. A single average can hide important differences.

Mistake 3: Making a test difficult by shortening the clock. Difficulty should come from the skills being assessed, not unnecessary pressure.

Mistake 4: Treating untimed tests as risk-free. Without clear instructions and controls, outside assistance or inconsistent testing conditions may affect what the result means.

Mistake 5: Changing rules after results arrive. A time limit, scoring method or retake rule should not be rewritten to suit a particular candidate or hiring manager.

Employer decision checklist

Before approving a timed or untimed test, confirm that:

• The main skills being assessed are clearly defined.
• Any speed requirement is genuinely related to the role.
• The format reflects reasonable working conditions.
• Question length and difficulty have been reviewed.
• A trial has identified obvious timing problems.
• Candidates receive clear instructions before starting.
• Accessibility requests and technical interruptions have documented processes.
• Scoring rules are approved before results are reviewed.
• Results are interpreted alongside their limitations.
• The format will be reviewed when the job or assessment changes.

A simple four-week implementation plan

Week 1 — Review the job. Meet with the hiring manager and people who perform the role. Identify where speed matters and where accuracy or careful judgement matters more.

Week 2 — Review the assessment. Map each section to the job requirement. Remove unnecessary reading and decide which sections, if any, need time limits.

Week 3 — Trial the test. Collect completion times, candidate feedback and common errors. Check for obvious technical or accessibility barriers. Avoid treating a small trial as definitive proof of fairness.

Week 4 — Approve the rules. Finalise candidate instructions, scoring, interruption handling and review dates. Train the people who will interpret results.

Frequently asked questions

Are timed tests more professional than untimed tests?

No. Professional quality comes from choosing a format that measures relevant skills fairly and consistently. A well-designed untimed exercise may be more suitable than a poorly designed timed test.

Do untimed tests allow candidates to cheat more easily?

They may create different opportunities for outside assistance, particularly in unsupervised settings, but time limits alone do not prevent misconduct. Employers should choose proportionate controls based on the purpose and risks of the assessment.

Should employers use the fastest completion time as a tie-breaker?

Only if speed is a justified part of the role and the decision rule was established in advance. A faster finish is not automatically evidence of better job performance.

Can a candidate be accurate but too slow for the job?

Yes, in some roles. The employer should establish what reasonable performance looks like and use an assessment that reflects that requirement. The same conclusion should not be assumed for roles where careful review is more important than speed.

Should all candidates receive exactly the same time?

Standard conditions support consistency, but appropriate individual adjustments may be necessary. Employers should follow applicable accessibility requirements and document justified exceptions.

Is a 40-question, 45-minute assessment suitable for every skill?

No. It is a session format, not a universal proof of appropriate timing. Suitability depends on the competencies, question demands, candidate population and intended use.

Can employers use both timed and untimed assessments?

Yes. A carefully designed process can use a timed routine task alongside an untimed case study or work sample. Each component should have a clear purpose and scoring rule.

Conclusion

The choice between timed and untimed skills tests should begin with the job—not with the clock. Where prompt, accurate performance is important, a reasonable time limit may add useful information. Where careful thinking, sound judgement and accuracy matter most, a strict timer may create unnecessary barriers.

Employers make better assessment decisions when they identify the skills they need, test under realistic conditions, explain the rules clearly and review the results with care. The aim is not to make candidates finish quickly. It is to understand whether they can do the work well.
