The Ramsay Mechanical Aptitude Test or MAT is an exam which was first published by Ramsay Corporation in 2004. The latest version of this exam is the MAT-4. The exam aims to provide a short assessment of the examinee's mechanical abilities, without taking into account his\her social and cultural background. Alongside the Bennett Mechanical Comprehension Test and the Wiesen Test of Mechanical Aptitude, Ramsay is one of the leading publishers of mechanical aptitude tests.
Created by Joël P. Wiesen, this mechanical comprehension test is distributed by several publishers, such as Criteria Corp. and Ramsay Corporation. It is considered to be one of the most reliable mechanical aptitude tests, along with the BMCT and MAT exams.
Bennett's Mechanical Comprehension Test is a test published by Pearson TalentLens Company. Originally known as BMCT-I, the exam has since been improved and replaced by version BMCT-II (created in 2014), which is more adapted to the needs of current employers.
