I know a lot of musicians in and out of the classical disciplines. I look at such resume bullet items with a very practical eye.
Typically, the "exams" and/or certifications are used as entrance prerequisites for many advanced programs of study, either at universities or private. They imply various levels of expertise. The Bachelors degree is more about employment opportunities and/or a prerequisite for Masters programs. The other really big implication are the social network of musicians afforded by going through any or all of these processes.
Some examples - my daughter-in-law has a Bachelors in music theory with accompanying teaching credential. She runs 4 different high school marching bands. But her real skills take her into performances all over the SF Bay Area. Her work in the schools affords many private students. No fancy letters.
My in-class CG instructor has a PhD in Theory and Masters in Guitar Performance from SF Conservatory. He shuns the academic politics, so he performs and teaches in private institutions. No fancy letters.
My online CG instructor has a Masters in CG Performance and is a professor at Linfield College, performs all over, and has copious private students. No fancy letters.
The Choir Director in my wife's church has a PhD in Theory, and a Masters in Choral Arrangement. He has deep connections to LampLighters, the Berkeley Rep, and other similar groups, representing a talent pool from which he regularly calls upon. His work is 7X24 with multiple choirs, private students, and of course, his professorship at UC Berkeley. No fancy letters.
Back to your question - all those fancy letters don't mean a thing to me. But they are meaningful to the academic hierarchy, for sure. I would not look at those alone or in isolation. In reviewing someone's qualifications, I'd want to see their real world accomplishments too.
