Questions
Idaho snow day questions
Idaho requires at least 990 instructional hours for grades 9 to 12, 900 for grades 4 to 8, 810 for grades 1 to 3 and 450 for kindergarten.
With local board approval, up to 11 hours of emergency closures for bad weather or facility failures can come off the yearly hours requirement.
All 114 in the state, by ZIP, with a page of their own for 24, including Meridian, Boise and Bonneville. Every page carries the district’s own snow record and the odds for its next three school mornings.
A typical Idaho district sees about 5 weekday mornings a winter with 2 inches of new snow or more, and 1 with 4 inches or more, counted on weekdays from December 1 through March 31 at each district’s nearest NOAA weather station over ten winters. The snowiest districts in the table see several times that.
Three school mornings, as far as the National Weather Service hourly forecast reaches. Weekends and the district’s winter break are skipped, so a Friday storm is read for Monday’s buses.
It reads the National Weather Service forecast for your ZIP through the night and the bus hours, adds winter alerts and the Winter Storm Severity Index, and measures the snow against what counts as a big morning for your district. The state rules come from the Idaho State Department of Education and the state code.
