Hi, the process is different for each school, but you can find a lot of great information at CAPTE: http://www.apta.org/ProspectiveStudents/. In general, you want to take the GRE’s in the fall and start studying this summer. Most applications are due around December or January, but some schools give preference to applications submitted earlier. You can start PTCAS at the beginning of July, and although it is complicated, they have a lot of information on their website and they will answer all your questions if you ask. It’s also a good idea to check with each school to which you’re applying to make sure you know what they expect from you. Let me know how it goes!
