  • 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

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?
