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

What is cct

Sequential Probability Ratio Test (SPRT)


The pros

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


The cons

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


Security considerations

Security Considerations

  • Innocent Conversations

    • Internet Brain Dump sites

    • Test Prep Agencies

    • Technology (text message, camera phones, tie cams)


Item exposure

Item Exposure

  • Over-exposure of items at popular ability levels

  • Computer routines to control item over-

    exposure (Simpson-Header Control)


Challenges

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


Future

Future?

  • More candidates!

  • Dietetics Education Task Force

  • Minimum for 3 Parameter = 300?

  • Rasch?
