Q.Is there a national standard for the number of school days per year?
A.
If you're asking about the United States, the answer is no. The U.S. government doesn't require a certain number of school days per year. Each state determines school-year length on its own.
According to the U.S. Department of Education, American schools average 180 days of instruction per year. That figure includes public and private schools at both the elementary and secondary levels.
A July 2004 report (MS Word document) from the Education Commission of the States lists each state's school-year requirements. Thirty states have 180-day school years, two have school years longer than 180 days, and 11 have school years shorter than 180 days. Minnesota is the only state that doesn't require a set number of days or instructional hours for schools. Each district can dictate its own school year.

Just for the Govs
By the way Govs aren't you Government folks going to 4 day weeks?
If businesses went to 4 day weeks, plus they had a 4 day school week, and Fridays were the off day, I could see it beneficial to families as far as being able to spend more quality time with their kids.
Of course mine are almost gone so it'd just be awesome to have 3 day weekends just for me !!
Actually I like Dmom's recreational idea, I would have never thought of that
