Wow, Ca dropped more days, I am assuming budget issues. My SIL teaches high school in Calif, I know summer school has become almost non existent and she does have some breaks that we don't have here in NV.
I hear you, NV mandates 180 days but doesn't limit the number of half days grrrrrr. When DD was in multitrack year round public school she had at least 4 half days a month - 2 for inservice and 2 so that teachers/classrooms could track on/track off. It was ridiculous.
She is now in a charter school - the first 2 days of school are 1/2's, the last day of school is a 1/2 and the one teacher in service day is the Friday before Christmas break. Thats it, Snow delays/cancels are rare, they expect us to sort out getting our kids to school. There is no busing etc. so that is not an issue.
We have standard breaks, 2 days at Thanksgiving, 2 weeks at Christmas, 1 week for Spring break. Labor Day in Sept., NV Day (the Friday closest to 10/31, we swap for Columbus Day), Veterans Day in November - MLK B-Day in January, the Presidents 3 day weekend in February and Memorial Day in May.
My DD's small Charter School sent home a ballot that offered us several different break options, including 3 weeks at Christmas, an additional week in the fall etc. All of these options meant we either started earlier and ended later or both. The overwhelming majority voted for the traditional calendar I noted above. I would have liked a 3 week Christmas break since DS is in college and we could have a week that was not part of the holiday rush, but I was out voted. Oh well....
We start school the same time as the local district but due to lack of what I call BS days, we actually end about 8-10 days earlier, give or take some for snow days.
