Test anxiety: what actually helps, according to the research

What test anxiety is, and when to get help

Test anxiety is anxiety tied specifically to being evaluated: worry before and during an exam, physical tension, and the experience of going blank on things you know. Some nervousness before a high-stakes exam is normal. Test anxiety becomes a problem when it disrupts your preparation, your sleep or your performance on the day.

This page is not medical advice. It summarises research on interventions for test anxiety and turns it into practical steps for certification candidates. If your anxiety is severe, if it extends well beyond exams, if you have panic attacks, or if it is affecting your daily life, talk to a doctor, a licensed mental health professional or your university's counselling service. The evidence below suggests structured professional help is exactly what works best.

What the research says works

The best summary of the evidence is a meta-analysis of randomised controlled trials in test-anxious university students by Huntley et al., 2019. It pooled 44 trials with 2,209 participants.

• Interventions reduced test anxiety, g = -0.76. In plain English, that is a moderate-to-large reduction: on average, students who received an intervention ended up with markedly less anxiety than those who did not.
• They also improved academic performance, g = 0.37, a small-to-moderate benefit.
• Behaviour therapy had the most support. Cognitive behavioural therapy (CBT), study-skills training and approaches that combine these were also promising.
• A caveat: the authors noted signs of publication bias, which means the true effects may be somewhat smaller than the pooled numbers.

Two points stand out. First, the interventions that work are structured programmes, typically delivered over several sessions, not one-off tips. Second, study-skills training appears among the promising approaches. Feeling prepared is not a cure for anxiety, but better preparation is part of the evidence-based package.

What the research says does not work (on its own)

One-off expressive writing

Writing about your worries just before an exam became popular after a widely cited classroom study, Ramirez & Beilock, 2011, reported that writing about testing worries boosted exam performance. Later research has not held up so well. A 2025 meta-analysis of 21 studies with 1,457 participants found a negligible, nonsignificant effect of single-session expressive writing on anxiety, and concluded that the literature fails to support it as a test-anxiety treatment (O'Meara et al., 2025).

Five-minute tricks

Ganley et al., 2021 tested four brief, 5-minute interventions with 300 college students before a maths test, including reappraising anxiety as a challenge or as excitement, expressive writing, and a "look ahead" exercise. None of them changed state anxiety or test performance. The authors suggest brief, one-off interventions may be too light.

That does not mean a quick breathing routine or a few calming words will hurt you, and if something helps you feel steadier, use it. It does mean you should not rely on a last-minute trick to fix anxiety that has been building for weeks. The evidence favours longer, structured work.

How to deal with test anxiety: practical steps

Here is what we suggest, based on the research above. None of it replaces professional help for severe anxiety.

1. Take it seriously early

If you know exams make you very anxious, look for help weeks before the exam, not the night before. Many universities and some employers offer counselling or CBT-based programmes. Structured programmes take weeks, so starting early matters.

2. Use study methods that build real confidence

Rereading creates a feeling of familiarity that can collapse under exam pressure. Students who reread become more confident without remembering more (Seban et al., 2024). Methods that test you, such as active recall and practice tests, give you an honest picture of what you know. It is reasonable to expect that an accurate picture is easier to trust than a feeling, though we know of no trial that tested this directly in anxious candidates.

3. Rehearse the exam conditions

Take timed, full-length practice exams in a quiet room, in one sitting, at the time of day of your real exam. The exam then feels like something you have done before. This is a practical recommendation, not a tested anxiety intervention.

4. Protect your sleep

Anxious candidates often cut sleep to study more. That backfires for memory: restricting sleep to 3 to 6.5 hours, compared with 7 to 11 hours, impairs memory formation (g = 0.29, a small effect), with similar consequences to missing a whole night (Crowley et al., 2024).

5. Plan exam day in advance

Decide the night before when you will leave, what you will bring and what you will eat. Read the candidate rules for your exam so there are no surprises at check-in. Fewer decisions on the day leaves less room for worry to grow.

Why certification exams can feel different

Certification candidates face some pressures that school exams rarely have, and naming them helps you plan for them:

• Money. Exam fees are often hundreds of dollars, and a retake costs the same again. Knowing your retake policy and cost in advance takes some of the weight off a single attempt.
• Career stakes. A job offer, promotion or contract requirement may depend on the result. Talk to your employer about what actually happens if you need a second attempt; the answer is often less dramatic than the version in your head.
• Unfamiliar formats. Online proctoring rules, room scans, adaptive question selection and performance-based questions can all add uncertainty. Read the official candidate guidance for your exam well before the day.
• Studying alone. Many candidates prepare alongside a full-time job, without classmates to compare notes with. Regular practice test scores give you the outside reference point a class would.

During the exam

The research on in-the-moment techniques is thin, so treat these as practical habits rather than proven treatments:

• Mark and move. If a question makes you freeze, mark it for review and answer the next one. Most certification exams let you return to marked questions.
• Read the question stem twice. Anxiety narrows attention; many errors come from misreading what is asked.
• Keep a pace check. Note the time at a quarter, half and three quarters of the way through. Knowing you are on track is calming.
• Expect hard questions. Adaptive and scenario-based exams are designed so that you will not know every answer. A hard question is not evidence that you are failing.

Limits of the evidence

• The trials in Huntley et al. were with university students. Professionals taking certification exams may differ, although the type of anxiety is similar.
• Publication bias means the pooled effects may overstate the real benefit.
• Brief interventions have been tested mostly before maths tests; results may differ for other exams.
• Anxiety research measures self-reported anxiety. A technique can change how you feel without changing your score, and the reverse.
• We have not found randomised trials of test-anxiety interventions run specifically with professional certification candidates.

How to use this for a certification exam

A six-week plan for an anxious candidate preparing for an exam such as CompTIA Security+ or the PMP:

1. Week 1: decide on support. If your anxiety is severe or has derailed exams before, book an appointment with a counsellor, doctor or psychologist now. Ask about CBT or behaviour therapy for test anxiety.
2. Week 1: low-stakes baseline. Take our free Security+ practice test or PMP practice test at home, untimed. The score is a starting point, not a verdict.
3. Weeks 1 to 4: short daily practice. 15 to 20 questions a day with explanations. Frequent, small, low-stakes tests make testing ordinary.
4. Weeks 3 to 6: timed sets. Once a week, a 30 to 40 question set under exam timing.
5. Weeks 5 and 6: two full rehearsals. Full-length, timed, at the same time of day as your exam, phone in another room.
6. Last three nights: sleep. Stop new study by early evening and keep a normal bedtime.
7. Exam morning: a light review of your error log at most. No new material.
