Preparing for the Exam

The CALT certification is a self-study course. Some companies offer to teach the course in a group setting, supplementing the lecture with reading and discussion. Others may opt to have technicians read the training manual and then meet in person to review and prepare for the exam. Finally, some candidates study and prepare solely on their own. Be sure to ask your company if they offer a training program.
