All private and international schools in Denmark are supervised by an inspector. Here is his report for the international department 2018
Kim Broström,
Inspector Ebbe Forsberg visited the school in February 2018, here is a quote from his report:
The bilingual department of Institut Sankt Joseph is a part of an old catholic school with a fine reputation and I can confirm that it is an excellent school with room for many kinds of leaners, particularly the ones interested in academics. The special needs department takes care of the students with all kinds of challenges.
