Presentation Transcript

  1. What is CCT? • CBT = Computer-Based Testing • CCT = Computerized Classification Test • Competent or Not Competent? • Focus on measurement precision • near cut score • Focus on reliability of decision

  2. The Testing Programs (CBT since 9/1/99)

  3. The Testing Programs

  4. The Testing Blueprints

  5. The Testing Programs

  6. Sequential Probability Ratio Test (SPRT)

  7. The Pros • Candidates love instant results! • Helps control item exposure (esp. with no review) • Year-round testing provides more flexibility - more locations • Computer testing provides more potential for creativity - fidelity

  8. The Cons • Quality control usually = once/yr. • Item analysis/review corrective “for next time” - not linked to candidate score • Expense • Sometimes variable-length test seen as disadvantage

  9. Security Considerations • Innocent Conversations • Internet Brain Dump sites • Test Prep Agencies • Technology (text message, camera phones, tie cams)

  10. Item Exposure • Over-exposure of items at popular ability levels • Computer routines to control item over- exposure (Simpson-Header Control)

  11. Challenges • Small sample size = Hard to get sufficient N for item analysis • Small sample size = Hard to get sufficient N for pretest items • Small sample size = Hard to get sufficient $ for program

  12. Future? • More candidates! • Dietetics Education Task Force • Minimum for 3 Parameter = 300? • Rasch? Text
