Average number of hours and minutes of sleep of students in grades K to 5 on school nights, as reported by a parent or guardian

The first step is to calculate the ‘usual number of hours slept’ for each student. The number of hours slept is calculated by subtracting the time of going to bed from the time of getting up, as self-reported by the students to the following two questions: At what time do you usually go to sleep when you have school the next morning? And when do you usually wake up on school mornings? This indicator is calculated by dividing the 'sum of all respondent number of hours slept' by the ‘total number of respondents' who answered these two questions about sleep.

Due to the very low response rate for the 2025-2026 parent questionnaire, survey results may not be representative of the overall student and parent population. Therefore, results should not be used for planning or comparing to previous editions of the survey. Some schools will not receive their K to 5 results due to the extremely low number of parents who responded.
