An educational award, a professional credential and a state license are different things. Before paying a deposit, confirm which pathway your intended role requires.
Education
Ask the program for its accreditation status, award type, admission requirements, clinical arrangements and published completion and examination outcomes. Confirm whether its graduates meet the education requirements for the credential you intend to pursue.
Credentialing
ARRT lists education, ethics and examination requirements. Eligibility depends on the pathway and individual circumstances. Ask ARRT directly if a past issue or a different educational background may affect you.
State rules
Check the licensing authority where you plan to work. Do not assume a credential or license transfers automatically.
