On Jan. 1, 2020, ARRT will begin using a new cut score for the Nuclear Medicine Technology (NMT) examination. Although we’ll continue to report the exam’s cut score as a scaled score of 75, the minimum number of correct items necessary to meet this passing threshold is a few points higher than it was in previous years.
The revised cut score reflects new performance expectations for entry-level nuclear medicine technologists. ARRT last updated the NMT cut score in 2000.
Since 2000, the field of NMT—and our NMT content specifications—have changed significantly, largely because of the increasing prominence of positron emission tomography (PET) and CT scans and the constantly changing availability of radiopharmaceutical compounds. When such changes take place, or when it’s been some time since we last evaluated the cut score for an exam, ARRT’s psychometricians conduct a standard-setting study.
In psychometrics, periodic evaluation of cut scores is considered a best practice. Such studies re-evaluate what level of performance is 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.
The standard-setting process helps to ensure that our exam appropriately measures who should and should not become certified and registered in NMT. We anticipate that the new cut score and our new performance expectations may lead to a slight decrease in the percentage of candidates who pass the NMT exam.
