It is not, but I didn't think ABET accreditation was a big thing for CS and was more common in engineering? CMU and Stanford, for example, do not have ABET-accredited CS programs, although MIT does.

A lot of CS programs are ABET accredited.

CMU and Stanford don't need anyone or any organization to tell the world they do a good job educating CS students. Not so clear if the CS dept is at the Small Town Liberal Arts College and Seminary.

But the other 4,999 schools CS programs, like the one being discussed at WGU, the source of the accreditation is a valuable signal.

At the bottom, the article says they are not ABET accredited.
