Happening at ARRT
On January 1, 2023, ARRT will begin using new cut scores for the Radiography and Sonography examinations. The revised cut scores reflect new performance expectations for entry-level radiographers or sonographers and replace the previous cut scores set in 2012 and 2000.
To determine an appropriate cut score, our Standard Setting Advisory Committee members reviewed each question from a representative version of the exam and rated the likelihood that candidates at or just above the passing threshold would answer it correctly. That process required multiple rounds of ratings and incorporated in-depth discussions with other committee members. The goal was to determine what level of exam performance would demonstrate sufficient knowledge and skills for a candidate to be certified and registered as an entry-level sonographer.
The advisory committees ultimately submitted their recommendations for the cut scores to ARRT's Board of Trustees. The Board reviewed all information from the standard setting studies and the committees' recommendations before adopting revised cut scores.
Why the change?
In psychometrics, we consider periodic evaluation of cut scores a best practice. Such studies re-evaluate the level of performance necessary to pass an ARRT exam. They give us confidence that cut scores are valid measurements of who should and should not earn ARRT credentials.
Radiography:
Since 2012, the types of radiography exams--as well as the skills and knowledge needed to perform radiography procedures safely and effectively--have changed.
Sonography:
Since 2000, the types of sonography exams--as well as the skills and knowledge needed to perform sonography procedures safely and effectively--have changed.
