The Canadian Forces Aptitude Test is a test done as part of the recruitment process, to determine the trades a candidate may be best suited for. Different trades have different requirements in each of the three categories. Higher scores allow you to choose more trades, lower scores limit your options and may even render you unsuitable for service! You should take every measure you can to maximize your chances at a high score, since your score will be on your file for the rest of your career!

This is important to note as it is common for members to change trades while in the military, and if your score is high enough for the other trade you want, you do not need to do the CFAT again. However if you initially get a low score but just enough for the trade you want, you will have to redo the CFAT in order to qualify for another trade you may want in the future!
