Philadelphia public schools hires ($15,000 stipend is what I heard). However, that was for a friend doing a masters in school psych. Not sure if they hire clinical folks and, if they would, (a) what the stipend would be and (b) whether the hours/experiences would count towards licensure (I know that in my home state majority of school-based hours do NOT count towards licensure). However, states boards differ in that (and many other) regards.
