Last year, Claire Noble-Randall woke up at 5:30 am every morning. She had to catch two buses to arrive in time for first-period chemistry at Ingraham High School in Seattle, US.

Ingraham starts at 8 am, but Noble-Randall often didn’t go to sleep until after midnight. “It was really hard not to fall asleep in class,” she said.

Her mom solved the problem this year when she discovered that other parents had hired a private city tour bus to take their children to the school.

“Now, she leaves the house at a much more reasonable time 7:10 in the morning…to catch the little tour bug at 7:23 am,” said her mother, Noelle Noble.

That may be one way to help students get more sleep. But more than 3,300 people have signed an online petition (请愿) looking for a better solution from the Seattle school district. Those who have signed the petition want all high schools and middle schools to start no earlier than 8:30 am. Most of Seattle’s high schools and middle schools start at 8 am or earlier.

Later start times for teenagers is an idea that some parents around the nation, have wanted for years. They’ve provided plenty of scientific evidence that teenagers tend to be night owls and delayed start times improve their health, mood, attention, and, in some cases, learning.

But attempts to delay start times for teenagers haven’t worked. Coaches don’t want late dismissals (放学) cutting into sports practices; community groups don’t want to wait longer for gyms and fields and before- and after-school programs don’t want to change their schedules.

This time, however, they’ve got Seattle School Board. President Sharon Peaslee on their side. She herself is the mother of two high school students. Peaslee hopes other board members will pass her plan calling on the district to find a way to make the changes.
