The school year at AIIAS begins the first week of August starting 2020 (see the Academic Bulletin for the exact starting date). August is the time you need to enter your Doctor of Philosophy in Religion program.
Classes are scheduled sequentially to complement and build upon each other so that you will have an educational experience with the greatest likelihood of success. Entrance at other times is not possible because you would have to take classes out of the proper sequence without having the appropriate foundation.
It is recommended that you plan to arrive sometime before the semester begins in August. Please allow enough time to arrange for your visa, meet with your program director, finalize your registration, prepare and take proficiency exams in Greek, Hebrew, and a modern language, and make housing arrangements.
