Yes. Students must apply to the program to be considered for admission. Just like medicine, nursing, and other health care programs, there are prerequisite courses (see below), minimum grades, and other criteria that determine who gets into the program.
PTA courses cannot be taken a little at a time according to a student’s desires. It is important to understand that students are accepted as a group into a program. The group is accepted and starts at the same time, stays together for all courses, and graduates together when all courses have been taken and passed.
