Exam anxiety: what the evidence says helps

What actually helps when worry about an exam becomes part of the difficulty of taking it? Research offers useful answers beyond quick calming tricks. Practice tests have evidence behind them. Reinterpreting stress has shown promise. Writing down worries immediately before an exam has a weaker record than the early positive research finding suggested. Sleep matters too, though its role as a treatment for test anxiety remains unproven in the research discussed here.

How common is test anxiety?

An NCERT journal article describes test anxiety as worry and tension around tests, sometimes accompanied by physical symptoms. A student can feel nervous despite preparing well. Nervousness alone does not mean they have a mental disorder.

A 2021 study published in the Indian Journal of Pediatrics analysed 2,158 schoolchildren aged 9 to 18 from rural and urban schools in six states. Researchers grouped their Test Anxiety Inventory scores into high, medium and low anxiety: 18 per cent, 48 per cent and 34 per cent of the sample respectively. The groups describe scores within this sample, rather than clinical diagnoses or how common test anxiety is across the country today.

The concern deserves attention. A review combining 238 studies linked test anxiety with poorer educational performance. The relationships across the variables studied were small to moderate. These links cannot tell us whether anxiety caused lower marks or predict an individual student's result.

Practise taking tests during preparation

Yang and colleagues' 2023 meta-analysis combined 24 studies involving 3,374 participants. Practice tests reduced test anxiety on average. The standardised effect size, Hedges' g, was -0.52, which the authors described as a medium effect. This measures the average difference between groups, rather than a 52 per cent fall in anxiety. Individual results can vary.

The way practice is organised matters. Easier tests tended to reduce anxiety more than difficult ones. Yet taking a quiz could itself feel more stressful than another learning activity. Most effects in the review concerned repeated classroom practice and anxiety about upcoming exams. Practice can feel uncomfortable even as it helps reduce anxiety about a later exam.

For students, a reasonable way to use this evidence is to include manageable practice quizzes during preparation. The review gives no ideal daily quota and no basis for constant high-pressure mocks. The average benefit also gives little reason to expect the same from a single difficult rehearsal.

Writing worries down: a weaker claim

Ramirez and Beilock's 2011 Science paper reported that brief writing about an upcoming test immediately before it improved scores, particularly among students habitually anxious about tests. The paper's two laboratory experiments and two randomised field experiments offered an encouraging early finding.

The newer review is less encouraging. O'Meara and Lovett's meta-analysis, published online in 2025 and in a 2026 journal issue, examined single-session expressive writing across 21 studies involving 1,457 participants. The pooled effect on anxiety was negligible and not statistically significant, at r = -0.05.

The initial performance effect was small, at r = 0.09, and statistically significant. After an extreme outlier was removed, it fell to r = 0.06 and was no longer statistically significant. These effect sizes measure differences, rather than percentage gains in marks. The performance finding depended partly on an unusual result.

The authors concluded that the available literature did not support single-session expressive writing as a treatment for test anxiety. Writing may still feel useful, and other forms of journalling are a separate question. But a pre-exam writing exercise has little support as a reliable solution.

Changing how arousal is interpreted

Stress reappraisal teaches people to see the body's immediate stress response as potentially useful when facing a demanding task. The aim is to change what those feelings mean; physical signs of nervousness can still be present.

In Jamieson and colleagues' randomised field experiment, 339 community-college students received reappraisal or an active control before their second in-class examination. Reappraisal led to less maths evaluation anxiety and higher scores on that exam and a subsequent one.

The finding is promising, though it comes from this particular setting rather than Indian schools. The published abstract gives no standardised effect size to show the size of the benefit. Reappraisal has limits: stress can be harmful, and serious distress needs more than positive thinking.

Protect regular sleep

Okano and colleagues' 2019 study used wearable trackers in an introductory college chemistry class. Of 100 students, 88 completed it. Longer, better-quality and more consistent sleep were linked with better academic performance. This observational study shows an association, rather than cause, and leaves sleep's role in treating exam anxiety untested.

Sleep duration and quality over the preceding week or month were associated with performance, while sleep on the single night before a test was not. This supports paying attention to regular sleep during learning. The finding about a single night leaves the risks of an all-nighter unanswered.

For general health, the US Centers for Disease Control and Prevention reports the recommendation of 8 to 10 hours per 24 hours for adolescents aged 13 to 18. Its guidance also recommends consistent bed and wake times, avoiding caffeine in the afternoon or evening, and switching off electronic devices at least 30 minutes before bedtime. Regular sleep problems warrant a conversation with a healthcare provider. These habits are general health guidance; individual treatment needs separate advice.

Support beyond self-help

Huntley and colleagues' 2019 review examined 44 randomised controlled trials involving 2,209 test-anxious university students. After treatment, students receiving the interventions did better on average than the control groups for anxiety, g = -0.76, and academic performance, g = 0.37. These figures measure standardised average differences between groups, rather than cure rates or percentage gains in marks.

The strongest subgroup support was for behaviour therapy. Cognitive-behavioural therapy, study-skills training and combined approaches showed promise, but publication bias, poor reporting and limited longer-term evidence reduced confidence. Some findings rested on few studies. Professional support has evidence behind it. Choosing an approach for a particular student still needs individual consideration, especially when applying university findings to schoolchildren.

Where to seek help in India

For children, the US National Institute of Mental Health suggests considering help when a child's emotions or behaviour last for weeks or longer, cause distress for the child or family, or interfere with school, home or friendships. A parent or caregiver can start with the child's healthcare provider. These are reasons to consider support, rather than criteria for a diagnosis. Families can ask for help sooner.

In India, Tele-MANAS offers free, round-the-clock mental-health support, including counselling for exam anxiety and referral when further care is needed. The Ministry of Health and Family Welfare's official PIB page lists the toll-free numbers 14416 and 1-800-891-4416, with support in multiple languages.

Unsafe behaviour or talk of harming oneself or others requires immediate help. For an immediate emergency in India, call 112, the nationwide emergency number identified by the Ministry of Home Affairs. It is distinct from routine exam-stress counselling.

What to do with the evidence

Build manageable practice into preparation and make regular sleep part of the routine. Treat promising techniques as options whose benefits can vary. Parents and teachers can help keep those expectations realistic. When coping is difficult, seek support: students can ask for help at any point, including before trying self-help exercises.
