MS schedule:

--one week band camp (3 hours per day with a concert on Friday night as a culmination)
--normal workday is 7am-5pm including a 1 hour and 20 minute sectional each day after school
--Saturday master classes 10am-12noon from Sept 1 through Oct 15

What MS schedule lacks:
--no demands on Christmas break
--no demands on July 4
--no Friday night games (4pm until 11pm minimum through football season)
--no Saturday marching contests
--no jazz band
--no winter guard
--no school musical
--no indoor drumline
--no graduation demands

Teaching middle school is DELIGHTFUL relative to teaching HS in my opinion.
