    PurposeTo determine if graduates of different types of educational programs obtain similar scores on the Examination in Radiation Therapy administered by the American Registry of Radiologic Technologists. The results will help inform discussions regarding educational requirements for radiation therapists.Methods And MaterialsTest scores were obtained for 531 candidates who had taken the examination for the first time in 1997, 1998, or 1999. Candidates were divided into the following three categories, based on the type of educational program attended: hospital-based certificate, associate's degree, or bachelor's degree. To determine if test scores were related to the type of educational preparation, analyses of variance were conducted separately to test for differences in total scores and section scores, and scores on test questions intended to measure critical thinking skills.ResultsCandidates with an associate's degree scored slightly lower than candidates with a bachelor's degree on the total test (p < 0.10) and lower than candidates with either a certificate or bachelor's degree on Section B of the examination (Treatment Planning and Delivery, p < 0.10). Baccalaureate candidates did not obtain higher scores than those prepared in certificate programs. On critical thinking questions, candidates with certificates scored higher than those with associate's degrees (p < 0.10). Some evidence suggested that candidates with a certificate scored higher on critical thinking than those with a bachelor's degree (p < 0.10), and that candidates with a bachelor's degree scored higher than candidates with an associate's degree (p < 0.10).ConclusionsAlthough some of the differences in the mean test scores among the three educational groups were statistically significant, all differences were small and do not support one type of educational preparation over another.
