Yes, charter schools are now constrained by law to preach the official government religion of atheistic Secular Humanism,..but...within the charter school framework there is opportunity for great flexibility.
In some states vouchers and tax credits are permitted for parochial schools. In these cases there is no restriction on the preaching of religion within the school.
