All religious observances of any kind should be removed from all schools and all school property - pretty much like Christmas and Easter were all replaced with Winter Holiday and Spring Break.  

It matters not what your religion is or how observant and devout you are; leave school property if your religion demands it.  That's what accommodation means, giving students time off to attend their religious services, not providing space and time for religious services in what should be a secular setting.  

No religious observances of any kind should be on school property.
