Sunnyvale ISD has a modified block. The class periods at the beginning of the day and end of the day meet every day. Then they have 3 classes on A/B block Monday thru Thursday and every class meets on Friday. All of the classes on Friday are a shorter length to fit in the day.
The coaches as well as the band director wanted rehearsal/practice every day. If it only been the band director wanting this it never would have happened but because the two combined as skill based classes the district went with this modified block.
Boys sports in the morning and girls sports at the end of the day.
Only works for a small school with one band or two bands if you have two rehearsals spaces.
What size school are you and how do your coaches feel about losing class time practice?
