Which is better: early or late school start times?

Do you think pushing school start times later into the day would help reduce sleep deprivation in teens? Or would you tend to sleep even later because you don't have to wake up early?

PLEASE DO indicate what country you're from and what level you're in, be it elementary, high school, or college. If you want you can also add what time your school starts and ends, and what time you go to sleep and the time when you wake up.

Thanks.

I live in teh US. IN florida where i used to live, my middle school started at 9:45 adn we got out at 3:45. When i went to high school, it started at 7:30, to 2:30. I will admit, in high school I was much more tired, but at teh saem time it prepares teens for the real world. When you get out of school, get a job, adn have a family, there is no such thing as sleeping in. I think that school start tiem around 8:00 is definately fair. Its a part of life, getting up early to make sacrafices fo rlife. Peopel have the weekend to sleep in. Hope this helps!!! Good Luck
