thanks.  I checked these and i seem to be doing things correctly.  I did it without repeated and computed the ICC manually and got an answer.

I can only guess your model is specified wrong, including the repeated() term (are you sure it is profid?), nesting (are profs nested in a group?), and covariance (is cat_tot_score continuous?). xtmixed or sem is probably a better choice for complex longitudinal data, like you suggested.
