I hate to hear that about social issues causing problems.
As far as the days.....the children attend 180 days.....and the teachers work 7 extra days on the front end, and 3 on the back end for 190 total.
So those 190 are the "required" days, but don't include the "actual" days. From what we've seen from my wife's own experience, and from many other teachers in the district, you can probably easily add 25% to that number. Weekends, training/development/lesson planning over the Summer, 12-14 hour weekdays. It adds up to more than 190 days of actual work here.
If teachers only work 190 days in your school district, then that is amazing and I wish more districts would use it as a model.
