Starting school late should be the guiding principle (原则) for high schools around the Puget Sound District. Next year, Seattle’s Nathan Hale High School will join the growing. list of schools starting a little later to allow students an hour’s extra sleep. As a national research has shown, a later start time benefits students both in learning and physical development.

For school leaders, it isn’t easy to make the change. Bus schedules have to be rearranged, sometimes presenting the districts with a choice of keeping traditional starting times at high schools or forcing elementary students to start much earlier. Some sports practice and event schedules can also he affected.

Around Puget Sound District, the Bainbridge Island School and Inglemoor High School and Mercer Island High School have either moved starting time later or created flexible (灵活的)schedules for students. Two of the Seattle district’s high schools, Summit and The Center School, already start at 9 a. m.

There are excellent reasons for such moves. Scientists have found that teenagers’ bodies usually aren’t ready for sleep until around 11 p. m. And the teens can sleep deeply until 8 a.m. A study in Minnesota found that students earned slightly better grades and experienced less depression (抑郁). There was also a significant improvement in school dropout rates. Other studies have suggested that teenagers with enough sleep relate better to their peers and their parents. These advantages are increasingly well known. Nathan Hale officials have been tracking the studies for six years. But change isn’t happening rapidly, if at all.

Some of the lack of rush to make changes comes from comfort with the existing condition. Parents - like the school leaders - are used to the present schedules. In Edina, Minnesota, however, parents quickly came to like the 8:30 a. m. start. A survey showed that 92 percent of parents preferred the schools’ new time to the previous 7:20 a. m. class bell.

Any school action that can deal with such difficult problems as depression and dropouts,while helping students with grades and getting along with parents, is one that is worthy of serious attention in every school district. Teenagers have adapted (使适应) their sleep needs to school schedules for generations. It’s time that more schools put the students’ needs first.
