TestGroup has various materials available for the use of The Bridge Personality 4-color test. These can be ordered separately, but you will also receive them individually if you opt for an introduction package. For example, there is a handy explanation booklet﻿ (The Bridge Personality: the booklet for candidates﻿), a package containing color cards of each color and, of course, the 4-color presentation (sheets) that you can use during your own training or workshop.
