Global Assessment of Functioning - Wikipedia, the free encyclopedia

The functional score is called GAF, and, as you will see in the Wikipedia link above, "school" and "occupational" functioning, in the way they are listed, appear to be fairly interchangeable.

So if you have a low Sanity score, do well in a tough school - with some stress, admittedly, but that is OK, etc., you should feel good about the work you have done, the analyst has done, etc.
