Steps
Use the CTEF 'Find Certified Tile Installers' locator at ceramictilefoundation.org/find-certified-tile-installers, searchable by zip code
Confirm the installer's name appears in the current locator listing rather than relying on a claimed certificate alone
Understand CTI is described by CTEF as the tile industry's only third-party assessment combining a multiple-choice exam and a hands-on practical test
Note the program requires at least two years of experience as a lead tile installer to sit for the exam, which can be used to sanity-check a claimed credential's plausibility
If the installer does not appear in the online locator, contact CTEF directly to confirm certification status rather than assuming the locator is exhaustive or always current
Known gotchas
CTI certifies installation skill/knowledge, not business licensing, insurance, or bonding — do not conflate certification with those separate requirements
The online locator's completeness/update frequency was not independently verifiable in this research — treat a 'not found' result as inconclusive pending direct contact with CTEF
CTI is a different, more introductory credential than the ACT specialty certifications — do not treat them as interchangeable
