  1. NBDE Part 1:A Meaningful Scoreor A Score Without Meaning? Nate Hawley Chair, ADEA Council of Students Joint Session Council of Students and Advanced Education Summit October 24, 2008

  2. Purpose of NBDE Part 1 “The purpose of the Part I and Part II examinations is to assist state boards in determining qualifications of dentists who seek licensure to practice dentistry.” --Joint Commission on National Dental Examinations

  3. Limitations of NBDE Part 1 “…comparing scores across certain years is not appropriate because they have different meanings in terms of the knowledge and problem solving skills of candidates.” --Joint Commission on National Dental Examinations “The Joint Commission had concerns about the use of scores for a variety of purposes, for which there is little, if any, validity evidence, e.g., ranking dental schools, faculty evaluations, and uses as an admissions tool.” --Joint Commission on National Dental Examinations

  4. Limitations of NBDE Part 1 “The Joint Commission is confident that there is little measurement error at the minimum passing point, but the error increases slightly as the scores depart from that point. This means for example that there is no guarantee that there is a difference in the knowledge and ability of the candidate who achieves an 89 and the candidate who achieves a 90.” --Joint Commission on National Dental Examinations

  5. NBDE Part 1 Performance --Joint Commission on National Dental Examinations

  6. Review So… • purpose is licensure based. • scores can’t be compared across years. • validity doesn’t justify scores used as admissions tool. • scores can’t differentiate knowledge difference across values.

  7. What Does This Mean? According to this information, other than a pass or a fail, NBDE Part 1 scores appear to be without meaning.

  8. Student Position • Move to Pass/Fail scoring for NBDE Part 1 is correct action. • We are not opposed to the use of a standardized test in advanced graduate admissions, but we believe the test should be validated for that purpose. • Given this information related to NBDE Part 1, the advanced graduate admissions process should be re-evaluated.

  9. Possible Alternatives • Statistically Valid Advanced Graduate Exam • Portfolios • Emphasis on Externships • Enhancing Interviews • More thorough Evaluations by Faculty at Student’s Dental School
