Some GCSE students are to test whether starting school at 10am could help them perform better at school.
Sleeping in late is seen as a rite of passage for teenagers, and now a new trial will examine whether deviating from traditional early start times in schools could help benefit a teenager's school work and well-being.
Experts from the universities of Birmingham, Oxford and Aberdeen are recruiting schools to take part in the study.
The trial will look at teenagers' sleep patterns and test whether a later school start time could benefit them.
Professor Paul Montgomery, lead researcher from the University of Birmingham, said:
The sleep study will focus on GCSE students from years 10 and 11 and the researchers are recruiting secondary schools across the UK to take part in the study.
