Despite university supervisors’ critical role in the success of PK-12 teacher candidates, research is limited on how to best prepare supervisors to mentor their supervisees and interact with cooperating teachers and school administrators.

Results indicate supervisors suffer overwhelming workloads, feel marginalized by their institutions, lack ongoing training, and are often unclear as to what their role is. The success of the cadres of clinical supervisors ultimately depends on training, but more crucially on full engagement by their home institutions
