Purpose
Purpose High-Stakes Achievement Test

  • Gather baselineanswer-changing patterns on a computer-based achievement test

  • Add to the knowledge base in this area


Methods
Methods High-Stakes Achievement Test

  • Third grade summative test in mathematics, one state testing program

  • One, 2012 form

  • 70 items, no time-limit

  • Students can review and change items as desired


Methods1
Methods High-Stakes Achievement Test

  • Assessment System Logs

    • Linear path through the test

    • Time spent viewing an item

    • Number of reviews

    • Number and pattern of changes

  • Unique benefit of CBT

Flagging rule application
Flagging Rule Application High-Stakes Achievement Test

Mean Wrong-to-Right Count (Target Form Only)

+ 8 Standard Deviations


Discussion
Discussion High-Stakes Achievement Test

  • Limitations

    • One form, one subject, one grade

    • Nested data

    • Distributions are not normal


Discussion1
Discussion High-Stakes Achievement Test

  • Answer patterns and elapsed time add to answer-changing interpretations


Future
Future High-Stakes Achievement Test

  • Further exploration of wrong-to-right changes by elapsed screen time and position of change

  • Other sources of variance

    • Item-factors (difficulty, position)

    • Student-factors (demographics)

    • Nesting (buildings, districts, classrooms)
