Constitutional Law II
Aid to Religious Schools
Generally, something like the Lemon test is used for government aid to religious schools.
The government cannot pay salaries at religious schools, but it may donate secular materials. (Supposedly because it trusts Christian schools to not use donated computers for religious purposes)
Services like tutoring and disability aid can be given to religious school students at their schools.
Aid like tuition vouchers can be given to the parents of students at religious schools.
