ACT Large Format Tile case studies

The ACT Large Format Tile credential is an advanced certification for tile installers who work with large-format tile and want independent verification of their skill. It is aimed at experienced setters, crew leads, and installers moving into higher-end residential and commercial work where big panels demand better substrate prep, mortar selection, and lippage control than small tile does. The exam blends a multiple-choice knowledge test with a hands-on practical assessment, so it measures both what you know and what your hands can do. Knowledge areas include substrate evaluation and flatness, mortars and adhesives, layout and planning, installation technique, leveling systems and lippage, movement accommodation and joint design, waterproofing in wet areas, cutting and tooling, and safety and industry standards. The ACT Large Format Tile case studies are 5 cases and about 2,208 words.
