From the 2003-04 Annual Report on Osteopathic Medical Education:
Please supply the number of student receiving instruction during the current academic year in the following topics include in the curriculum during any of the four years of medical school. Indicate the number of students receiving instruction in each of the categories (covered in required courses, covered in elective course, covered in clerkship rotation)
Although the question is framed to count the number of students, the number of colleges can be derived by counting the number of responses in each of the categories.
The Liaison Committee on Medical Education (LCME) Annual Medical School Questionnaire is fielded annually to all accredited medical schools in the United States that grant the M.D. degree. Overall response rates to the survey are 100%, and the response rate for the question used for this subobjective is typically 100%.
