may not discriminate among religious groups. That is to say, the program must be administered in a fair and even-handed manner so that all religious groups are treated the same. It should be noted that schools are not permitted to endorse or promote religious instruction, even when it is held off campus. Solicitation of students to attend religious classes may not be done at the expense of the school,(9) and only those students whose parents have signed permission slips should be allowed to attend. Students who do not wish to attend may not be penalized. Of course, schools may not rent their facilities to religious groups for religious instruction during the school day.(10) The question has arisen whether schools may give academic credit for released-time courses. Although the answer remains unclear, it is likely such a program would be unconstitutional, especially if credit is not given for other nonschool courses. There is very little to distinguish many of these religious courses from a religious education class, a nonacademic exercise for which schools could almost certainly not give credit.(11)...
