In the United States, religious education is often provided through supplementary "Sunday school", "Hebrew school", or catechism classes, taught to children at their families' places of worship, either in conjunction with worship services or some other time during the week, after weekday school classes. Some families believe supplementary religious education is inadequate, and send their children to private religious schools, called parochial schools when Catholic, day schools or yeshivas when Jewish. Many faiths also offer private college and graduate-level religious schools or seminaries, some of which are accredited as colleges.
