Montgomery County Public Schools have decided to moved back middle and high school start times by twenty minutes.
Start times for elementary school will be moved back by ten minutes.
This decision comes after much debate and follows Tuesday's 'sleep-in' protest.
Students and parents held the demonstration, complete with sleeping bags and pajamas, to try and show the importance of getting more sleep before going to school.
The start time changes will be put into place for the 2015 - 2016 school year.
