The time of day can affect performance

Research found that the time of day affects students' performance in schools. The effect of both time of day and breaks on students' performance on standardized tests were measured. The findings were:

• The later in the day the test was, the lower student's performance on the test.
• A 20- to 30-minute break caused an improvement in test scores.
• Low-performing students were more affected by breaks than high-performing students.
