Reply back with disagreement and your reason

You've got that backwards. All the studies say HS students need morning sleep the most. And an 0730 start, requiring an 0700 bus and an 0600 wake-up is too goldurn early.

I respectfully disagree. Many studies have shown that teenagers actually have a naturally later sleep-wake cycle, causing them to stay awake later at night and struggle to wake up early in the morning. Starting school later would allow them to get more sleep and improve their overall well-being.
