CASAA is the centralized application to Anesthesiology Assistant programs. Some programs may have supplemental materials. Be sure to check each program's requirements.
CASAA application opens in March each year and closes the following February. Be aware that individual programs may have much earlier application deadlines in addition to supplemental applications that will need to be submitted. It is important to apply as early as possible. Most programs start looking at applications for invitations to interview as early as Summer and that is for their regular cycle not Early Decision. Early Decision requirements will need to be completed even earlier with dates depending on the specific programs.
The CASAA is a service of the Association of Anesthesiologist Assistant Program Directors (AAAPD).
