In this book, Allan Glatthorn examines differentiated supervision, an approach
to supervision that provides teachers with options about the kinds of supervisory and evaluative
services they receive. In general, the differentiated model offers intensive development to
nontenured teachers and to tenured teachers with serious problems. The rest of the faculty receive
options about how they foster their professional development, working in collaborative teams in
a cooperative development approach or using a self-directed approach. The evaluation processes
are also differentiated, depending upon tenure status and competence.
