Many religious denominations accredit their own schools. There are, however, some independent accrediting organizations like the Association of Independent Christian Colleges and Seminaries and the International Association for Christian Educational Accountability, that are recognized as accepted accrediting vehicles by most Christian schools.
The reason many Christian schools choose not to become accredited is that they offer an education that is more focused on values and, in the case of seminaries, on doctrine. Those are areas in which secular accreditation would not provide adequate direction. In addition, The IACEA website cites the high cost of accreditation through secular avenues as one reason many Christian schools choose not to follow that path. For those schools choosing to accredit through one of the major Christian organizations, however, the process will be similar to secular accreditation
Ministry and education: Your ministry avocation is one of those areas where God’s will and plan is more important than anything else. In fact, for those already serving in ministry, a degree from a highly credible though governmentally unrecognized school may be the smartest choice. Especially when you can receive a quality online seminary education for a fraction of the expense associated with regionally accredited schools. We should not forget that, especially in the Christian tradition, academic freedom is considered a cornerstone of religious liberty. Of course, so is academic responsibility! Therefore, any program of study leading to a theological degree should be both Biblically sound, and academically honest. At NTS, you can be assured of such integrity with quality educational materials based soundly on Biblical principles.
However, if you are concerned whether your church or place of employment will accept you with a degree earned through a privately accredited school, that is not regionally accredited, then you should simply inquire concerning the same. Remember too, that even with degrees earned from regionally accredited schools; there could be restrictions on what kind of degree is recognized. Always inquire first, since in some cases, denominations and ministries may not accept degrees from secular schools, or schools not affiliated with a specific denomination or organization.
