The tables below summarize the auto glass knowledge
categories from the job survey conducted industry wide. This information
has been divided into knowledge areas called classes. These classes
together add up to 100% of what candidates needs to know to become a
certified auto glass technician or certified master auto glass technician.
For example, in the certified auto glass technician table, the knowledge
area "safety" is 14% of the exam. Under this major topic or "Class"
are 8 specific sub-topics that make up the items or Class. Also listed
is the approximate number of questions on the exam from each knowledge
area.
Make sure to review each knowledge area to determine the specific topics
of study. All areas should be reviewed and understood.
