The part-time Master of Arts in Teaching option is designed for career changers and for individuals who need more flexibility to earn teaching certification. This 39-credit option begins each semester and allows students to progress in the course work at their own pace within the 5-year time limit set for completion of the degree. Candidates take courses with full-time MAT candidates at both the Baltimore and Columbia campuses. Successful candidates are eligible for certification and earn the degree of Master of Arts in Teaching (MAT). As the final step in the program, candidates complete a full-time, 100-day clinical internship over two semesters during which time they are not allowed to hold outside employment, unless they are a full-time teacher in their own private or public school classroom.
