The Advanced Certifications for Tile Installers (ACT) program has been created through the combined efforts of five organizations including; the Ceramic Tile Education Foundation (CTEF), the International Masonry Institute (IMI), the International Union of Brick Layers and Allied Craftworkers (IUBAC), the National Tile Contractors Association (NTCA) and the Tile Contractors Association of America (TCAA).

The purpose of the ACT Certification program is to establish a testing mechanism which evaluates the skills and knowledge of tile installers who have been pre-qualified by being either a Certified Tile Installer (CTI) through the Ceramic Tile Education Foundation (CTEF) or a journeyman tile setter who has successfully completed the apprenticeship training program conducted by the International Union of Brick and Allied Craftworkers (IUBAC).

The intention of the ACT program is to provide a level of consumer confidence for tile installation procedures that exceed ANSI standards and TCNA guidelines for floor and wall. It is intended to demonstrate the knowledge and hands-on skill of the experienced tile setter. It is not intended as a training program. ACT certified installers represent the pinnacle of performance in the tile trade and maintain a level of excellence superior to non-ACT certified installers.

The ACT Shower installation certification is intended to demonstrate that the certified installer maintains the knowledge and hands-on skills to install a TCNA Handbook method B415 shower installation. It is intended to provide consumer confidence that the finished installation will be free of leaks, and moisture issues.
