Publishing an Adaptive Test

  • Write Items
  • Field Test Items
  • Select an Operational Pool
  • Publish Pool
  • Distribute Pool
  • Administer Tests
  • Rinse and Repeat

Problems with Publishing

  • The static pool

    • Restricts content
    • Restricts psychometrics
    • Restricts corrections
    • Structures item exposure
  • The publication process

    • Creates logistic problems
    • Slows response to new content
  • Item filtration – An alternative to test publishing

    • Realtime test creation
    • Begins with entire item pool
    • Removes items until one item is chosen to administer

Research Questions

  • Since filtering adds constraints, what is the psychometric impact?
  • Can we use filtering to control item drift?
  • How does filtering interact with item selection?
