Admission is selective but accessible to qualified working teachers: a 3.25 GPA is the standard bar, with a conditional path for candidates in the 3.0–3.24 range, and an appeals process (using GRE or GMAT scores) is available for borderline applicants. Beyond transcripts, evidence of leadership ability and teaching effectiveness through your self-disposition document and mentor’s endorsement is important. Prior roles like instructional coaching, committee leadership or department leadership all count as relevant experience, even if you haven’t held a formal administrative title yet.
