Hello Gunter. You didn't say where your sister wants to work.

In the USA someone with an MA in Social Work, Theology, or Counseling can go on to become a licensed Counselor.

In Switzerland the laws are much more restrictive. If she wants to work in CH, a BA & MA in Psychology are absolutely mandatory, otherwise she cannot get licensed. That being the case, ZH University would be her best choice. The Jung Institute in Kusnacht and ISAP (International School for Analytical Psychology) www.isapzurich.com in ZH, as already mentioned, are both post-graduate.
