There is not a separate deadline to enroll in an edX program. You can use the bulk enrollment feature on the program's home page to enroll in all courses at the same time if you wish. Or you can enroll in each course separately. After completing all courses on the verified track, you will receive the program credential.
If you wish to continue your education after earning a MicroMasters credential, please contact RIT Online (firstname.lastname@example.org / 585-475-2400) to speak with a program advisor about application materials and enrollment deadlines. We recommend submitting all application materials a minimum of 6 weeks prior to your intended start date.
