ndakota,
ACE is actually accredited by The Higher Learning Commision (HLC) and is a member of the North Central Association of Colleges and Schools (NCA). They are also accredited by the Teacher Education Accreditation Council (TEAC). In my experiences, as a teacher in Arizona, my school district and the Department of Education are honoring my degrees through ACE. I obtained a M.Ed. in Curriculum and Instruction '12, Educational Technology '14, and currently working on my Internship with the Educational Leadership degree, which should allow me to finish in early July '15.
As with all things, I called the Teacher Licensure at the Arizona Department of Education to verify they would accept my Educational Leadership graduate courses/internship for my eventual Principalship Licensure. After going over my transcript(s) with them, they accepted the graduate course I have taken, and will be taking. Additionally, my school district has accepted my degrees through ACE. If (as you put it) the "purpose of the degree would be for a bigger pay scale"? My school district has honored my master's degrees, and moved me to a bigger pay scale due to my path with ACE.
I had a limited amount of time with coaching sports and teaching, to go to a traditional brick and mortar school. After many months of research back in 2011, ACE made the most sense for me. I have actually convinced my department chair to take on the C&I degree, and she will finish in May of this year. I talk to people about ACE, whenever I get the opportunity to do so.
