There are actually enough schools in the NCCAA (gotta squish that extra "C" in there) for their to be two divisions. 42 in D1 and 37 in D2. Portland Bible College is actually in D2.
According to their web site, it looks like the only local school in the NCCAA is Geneva College, and they are D1. So they play at a higher level than Portland Bible College. But Geneva College is in the President's Athletic Conference, which is the NCAA D3 league with schools like Thiel and Grove City and St. Vincent. So I wonder if the NCCAA is more of a loose affiliation rather than a full scale confederation of school like the NCAA is.
