What is an Operative Plasterers and Cement Masons Apprenticeship Program?

As part of its long-standing tradition of pursuit of excellence, the OPCMIA, in the post-war era, began to establish apprenticeship to assure a constant supply of highly skilled craftsmen. Just as the OPCMIA advocated use of quality materials, it also demanded quality Plasterers and Cement Finishers who were properly trained in the craft. In 1946 the union joined with the Contracting Plasterers' International Association and the Associated General Contractors to establish the National Apprentice Training Standards. Through this program the union was able to guarantee a steady flow of qualified Plasterers and Cement Finishers to an ever-expanding construction industry. Working closely with the Veterans' Administration, the union indentured a large number of returning servicemen into apprenticeship programs.

OPCMIA Apprentices receive a minimum of 144 hours of classroom training, plus hands-on and/or on-the-job training.
