What is the best time to take examinations?

A paper revealed on July 24, 2025, by Carmelo Vicario et al., titled ‘Timing Matters! Academic assessment changes throughout the day’ in the journal Frontiers in Psychology presents an evaluation of the tutorial efficiency of over 1,04,552 college students throughout Italy. The research finds that the time at which they take their examination issues. Examinations performed between 11 am and 1 pm had been discovered to provide excellent outcomes, with these taken at round midday being the best, whereas these performed between 8 and 9 am and between 2 and 5 pm threw up poorer outcomes.  

The timing of important selections can thus have far-reaching penalties. The success fee adopted a bell curve with a peak at midday. That is, there was no important distinction in the likelihood of passing the examination if one sat for it at 11 am or 1 pm, however the possibilities of passing had been decrease if the examination was taken at 8 or 9 am or at 3 or 4 pm. The likelihood of passing was equal in the early morning and in the late afternoon.  

“These findings have wide-ranging implications,” Prof. Alessio Avenanti of the University of Bologna and a co-author of the research stated. “They highlight how biological rhythms, often overlooked in decision-making contexts, can subtly but significantly shape the outcome of high-stakes evaluations.”

Although the research didn’t determine the mechanisms behind this sample, the peak in the variety of college students passing at noon is in line with proof that cognitive efficiency improves over the course of the morning earlier than declining throughout the afternoon. Students’ falling vitality ranges could lead on to diminishing focus, compromising their efficiency. Professors may additionally expertise choice fatigue, inflicting them to grade reply papers extra harshly.

Meanwhile, poorer outcomes earlier in the day may very well be down to competing chronotypes, or physique clocks. People of their early 20s are normally evening owls whereas folks of their 40s or extra have a tendency to be morning larks. The college students thus may additionally present sleep inertia: low cognitive efficiency at a time when the professors are most alert.

“To counteract time-of-day effects, students might benefit from strategies like ensuring [good] quality sleep, avoiding scheduling important exams during personal ‘low’ periods, and taking mental breaks before performance tasks,” Dr. Vicario, of the University of Messina in Italy, urged. “For institutions, delaying morning sessions or clustering key assessments in the late morning may improve outcomes.”

But extra analysis is wanted to totally perceive the elements that contribute to the affect of the time of day on tutorial efficiency and to develop methods to guarantee fairer assessments.  

“While we controlled for exam difficulty, we can’t entirely exclude other unmeasured factors,” stated Prof. Massimo Mucciardi of the University of Messina and a senior writer. “We couldn’t access detailed student- or examiner-level data such as sleep habits, stress or chronotype. This is why we encourage follow-up studies using physiological or behavioural measures to uncover the underlying mechanisms.”

While this analysis was in Italy, the findings might effectively apply in India, when college students seem for a lot of entrance exams, that are usually held throughout the daytime, with morning and afternoon periods. For instance, the Common University Entrance Test (CUET) is performed in two slots at 9-12 am and 3-6 pm. If we go by the Italian instance, the slots are higher off being at 9/11 am and 12-2 pm.
