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?
