I'd like to answer your question, but it's not completely clear to me
what your question is.  In general, we want ns to be widely
used---it's used at public schools (like the UC system), private
schools (like USC and U. Penn.).

There shouldn't be a problem using it in similar contexts for
education at for-profit institutions like U. of Phoenix, although if
you're concerned, please contact me directly.
