I need help validating an online college?

Regional accreditation by the Higher Learning Commission or another regional body is the so called "good type" of accreditation.

Let me share some advice with you though. Even though it has the right accreditation doesn't mean that industry will still respect it equally with other accredited universities. It might seem more convenient to go the online route, but unfortunately industry treats (and will most likely continue to for a long time) online education with very little respect. If I were you, I would do anything to try to go to a college that has physical classes just because of that. Go to community college for 2 years, then transfer to a local 4-year university. That route will lead to a much more respected degree than the online alternative (at least for the foreseeable future).

Also, avoid Walden and other for-profit schools at all costs. They are very literally businesses with shareholders that make their profit off of your tuition. They'll do whatever they can to increase profits from hiring the cheapest and crappiest professors, accepting all students to increase their revenue base regardless if they even have the ability to graduate, and having absolutely ridiculous fees and costs considering what they're bringing to the table. They have reputation of being worse than community colleges at about 5-10 times the cost. Their degrees are looked down upon (to say the least) in the professional world.
