What is a Certified Tile Installer?

A Certified Tile Installer is a lead installer with a minimum of two years full time tile certified tile installer study guides, columbia missouri, bathroom remodeling expertsetting experience.  I earned my CTI by passing a hands on test and an open book test.  The open book test I took online, I had to travel to Kansas City for the hands on portion.  My hands on test was evaluated by a member of the Ceramic Tile Education Foundation (CTEF).  The Ceramic Tile Education Foundation started the CTI program to combat the lack of skilled installers in the trade.  I know several installers that have had to make several attempts at passing their test.  Fortunately, I was able to pass my CTI on the first attempt.

What is Covered in Open Book Test?

Hands On Test

Completed CTI Module

When I got to Kansas City I could pick my own testing module.  The testing module consists of a wood floor substrate and wall studs.  It is the installers responsibility to properly cover the substrate with vapor retardant and backer board.  The evaluator uses ANSI standards to score the hands on test.  The module has only about 20 square feet of tile to install and every aspect has a feature.  The floor has a border and diamond inserts that must follow a specific pattern.  The wall consists of a straight lay pattern and it has a diamond insert.  The top of the knee wall must be properly sloped and all changes of plane must be treated appropriately.   The CTEF gives each installer a sample grade sheet, so we know what the evaluator is looking for.

Passing Grade

To receive the Certified Tile Installer certification, you must receive a cumulative score ofcertified tile installer certificate, columbia missouri, 85%.  The hands on test is worth 75% while the hands on test is worth 25%.  I figured I needed 150 or better on the  written test and 80% on the hands on.  Knowing that results typically take 3-4 weeks to get back I was curious about retaking the test.  An installer can take the test twice in six months.  If the first attempt is not successful you will be notified of your weaknesses and to schedule your makeup test.  The makeup test is not as expensive as the first attempt.  You receive your certificate if you pass, but your score is not given to you.
