One of the most notable single acts of TMCA was to establish an organization for providing both educational and practical information and support to the judges, clerks, court administrators, and prosecutors who work in the municipal courts. In 1983, TMCA was selected by the Texas Supreme Court to receive and administer a grant to provide continuing legal education to Municipal Court personnel. In 1994, the authority to award the legal educational funds was transferred from the Texas Supreme Court to the Texas Court of Criminal Appeals. The Texas Court of Criminal Appeals selected TMCA to continue to receive and administer the grant funds.

To provide the continuing legal education, TMCA created the Texas Municipal Courts Training Center in 1983; in 1994 the name was changed to the Texas Municipal Courts Education Center (TMCEC). TMCA is the sponsor of the Texas Municipal Courts Education Center and through the Education Committee provides oversight to assure that quality educational seminars meeting state mandatory education requirements are presented at various regional sites each year. These legal seminars, the "800 helpline", the books and manuals, etc., are the result of activities initiated by TMCA.

The Boards of Directors for both TMCA and TMCEC are comprised of the same people and both organizations share some common purposes.  Board members are mindful that each entity's functions need to be isolated to comply with TMCEC grant conditions.
