The "Friday Effect": School Attendance over the Week

Using newly released detailed data on absence from school, we find a "Friday effect" - children are much less likely to attend schools in England on Fridays. We use daily level data across the whole of England and find that this pattern holds for different schools and for different types of absence, including illness-related authorised and unexplained unauthorised absence. The Friday absence rate is 1.5 percentage points (20%) higher relative to the rest of the week. For authorised absences, the Friday rate is 0.81 percentage points higher than Monday to Thursday, while for unauthorised absences it is 0.71 percentage points higher.

Furthermore, we document a social gradient in the "Friday effect" for unauthorised absences, where the effect is larger in more deprived areas. This is especially the case for secondary schools. Similarly, in secondary schools the "Friday effect" is 51% larger in areas with the highest rates of persistent absence compared to areas with the lowest persistent absence rates. We explore reasons for the “Friday effect” and do not find evidence that parents working from home explain the higher absence rate on Fridays. We do find that Friday absences are greater in weeks that preceded either a bank holiday or half-term – suggesting that extension of holidays or trying to avoid holiday traffic might go some way to explain the patterns that we find.

We show that eliminating the "Friday effect" could lead to an improvement of 1.15% of a standard deviation in test scores and a 0.14% to 0.25% increase in later life income. Tackling weekly absence patterns may therefore help to raise attainment and reduce inequalities.
