Limited Scope X-Ray exam requirements & cost
Straight from the certifying body — separate from what we charge for the study portal.
The ARRT Limited Scope of Practice in Radiography examination has a core module and separate procedure modules for chest, extremities, skull and sinuses, spine and podiatric radiography (ARRT content specifications, implemented January 1, 2023). Each state decides which modules a limited-scope operator must pass, so the exam you take may be only part of what this portal covers. The content specifications give each core and procedure area a share of the questions; radiation protection is the largest core area at 13.33%. ARRT and your state agency set the passing standard; check the ARRT candidate handbook your state publishes. The portal shows percentages only as a self-check. ARRT charges an examination fee that depends on the state program; ask your state licensing agency or check the ARRT state exam fee schedule. The content outline spreads questions across 10 areas; the largest are Radiation Protection (Core) (13.3%); Extremities Procedures (11.9%); Spine Procedures (11.9%). The full list of areas and weights is on the portal exam page. Set by your state licensing agency; ARRT administers the exam for states that use it.
