Performance Regulations
“an organization in a four year school may repeat a selection in the fourth year after the initial performance”

I’m a simple minded band director who needs help translating this....

My seniors played a piece when they were freshmen at UIL C&SR contest, does this mean they could potentially do it again this year, being their fourth year or that there must be 4 years pass so the band would be able to perform it next year?

Please help
