The Porcelain Enamel Institute has created a standardized grading system for ceramic and porcelain tile. The PEI rating categorizes tile by its specific intended use and its capacity to resist wear from foot traffic. The ratings are recorded on the packing of all tile makers. Selecting the proper tile level for any specific application is simplified as a result of this rating system. The PEI rating does not consider price, and every level of tile is priced differently due to the manufacturing processes. Tile with a higher score is more expensive to make and will cost the customer more.
