Recently I've heard East MS offers choir, band, orchestra, or GTT to all incoming 6th graders. At West MS the only choices are choir or band-orchestra. Why does one school offer additional classes than the other?

EMS and WMS offer the same elective classes to all 6th graders:  band, choir or orchestra for music on alternating days (purple or white) on the opposite day students take an arts rotation made up of a semester of PE/Health, nine weeks of art and nine weeks of GTT.
