Once you have limited the number of colleges by filtering for things that are important to you, like cost, and location, the best way to select a program is to review the programs for several schools. Read the course catalog and find classes that interest you, and find out if they are a part of the forensic science curriculum. It is a time consuming process, but it is worth understanding what classwork you will need to complete at different schools. In addition, if you have the ability to tour the schools, it will help you figure out if it is the right fit for you.
