Students apply to physician assistant programs through the Central Application Service for Physician Assistants (CASPA). CASPA requires letters of reference to be submitted electronically directly to CASPA (letters on printed media are not accepted) and not all schools welcome a committee letter. Check the requirements at each school to which you intend to apply.
Speak to your advisor concerning the requirements and your preparation for application. You will be required to have a letter from a PA whom you have "shadowed," as well as letters from faculty members.
There are 10 physician assistant programs offered by universities in Florida.
