Students typically start school between 9:00 am to 9:45 am. Actually, Helsinki is thinking of creating a law stating that schools cannot begin before 9:00 am because research has consistently proved that adolescents need quality sleep in the morning. The school day usually ends by 2:00 or 2:45. Some days they start earlier and some days they start later. Finnish students’ schedules are always different and changing; however they typically have three to four 75 minute classes a day with several breaks in between. This overall system allows both students and teachers to be well rested and ready to teach and learn.
