Standardized Tool for the Assessment of Radiology Students

Standardized Tool for the Assessment of Radiology StudentsThe Standardized Tool for the Assessment of Radiology Students (STARS), a collaborative effort of the Alliance of Medical Student Educators in Radiology (AMSER) and the American College of Radiology (ACR), provides medical schools with a national, web-based question-item database and exam-taking system to use in assessing students throughout their radiology courses.

Instructors can create and administer their own web-based exams using the bank of multiple-choice questions — or use AMSER-created and -vetted exams. The STARS editorial committee is in charge of editing the questions and creating standardized exams.

The question-item database, transferred from Radiology ExamWeb (REW), consists of over 2,800 edited questions. At launch, the exams created by the editorial board will be available to all users. Exams created by instructors will be available to the instructors' institutions only. Additional exams will be available on the public site in future. Due to the complexity of question transfer from REW, some areas remain a work in progress.

Use of STARS will be free for the first year after launch. Thereafter, there may be a fee to use STARS (to be determined).
