It is important for kids to arrive at school on time and ready to learn. Students who arrive late say they feel like they miss a lot and often spend the entire day trying to catch up.
Even being just 15 minutes late students may miss out on going over the day's schedule, working independently on an assignment, taking a test or interacting with each other as a group.
The same goes for leaving early at the end of the day when they may miss catching the last few minutes of instruction, have questions answered and getting homework assignments.
