Yes, many teachers and administrators do see a salary bump after completing their master's degree. Having an M.Ed. with the administrative or behavioral SPED specialization could make you eligible for a higher pay grade, more teaching credit or a stipend paid out over a period of time. A master's degree may also lead to a promotion or better-paying job opportunities across the balance of your career.
Individual state and district compensation policies can vary, of course, so check with school districts directly for additional information.
