All students in the Boise, Meridian, Nampa, Caldwell, and most other school districts in the Treasure Valley get the day off Thursday because of bad weather conditions.
A snow storm that moved into the Treasure Valley overnight left snow and ice covered roads behind, making travel dangerous.
The Melba, Notus, Marsing, Middleton, and Wilder school districts have all closed the schools for the day. Schools in the Kuna School District are open Thursday, but after-school activities, meetings and practices have been canceled.
"We want to make sure people get home before dark," said Wendy Johnson, assistant superintendent for Kuna schools.
Johnson said snow accumulation in the Kuna area this morning wasn't significant enough to declare a snow day. Kuna schools had a 75 percent attendance today, as some parents opted to keep their kids home.
Most Catholic and charter schools are also closed, including Bishop Kelly High School School in Boise.
All classes at the College of Idaho are cancelled Thursday.
Boise State University's regular classes don't start back up until later this month but all other classes scheduled for today are still happening, officials said Thursday morning.
Also canceled Thursday are Boise's Just for Kids programs and Boise Evening School.
The last time the Boise School District had a snow day was Dec. 1, 2010, according to district spokesman Dan Hollar. Prior to that, there was a snow day Jan. 30, 2008.
