proboblly 9 to 11/2 hours.

AnswerHe should probably get about 9-1/2 hours.

As per:

http://www.webmd.com/parenting/guide/sleep-children

7-12 Years Old: 10 - 11 hours per day

At these ages, with social, school, and family activities, bedtimes gradually become later and later, with most 12-years-olds going to bed at about 9 p.m. There is still a wide range of bedtimes, from 7:30 to 10 p.m., as well as total sleep times, from 9 to 12 hours, although the average is only about 9 hours.

You will find all the sleep requirements for children from newborn to 18 years @ the above link as well.

Depends on when they have to get up. At this age they need at least 8 hours of sleep so retract that from the time they need to get up. I would also retract a extra hour in case they wan to read or something.

I'm pretty sure you mean what time should a nine year old go to bed, and 9yr olds should have from 8-9 hours of sleep so they should go to sleep around 8 or 9, it also depends on what time they have to wake up.

This advice varies depending on who you ask, but I'd say about 9:00 p.m. on a school night and 9:30 p.m. on a weekend/holiday.
