The current study was designed to extend the current |
|
literature to study scale drift in CAT as part of |
|
improving quality control and calibration process for |
|
ACCUPLACER, a battery of large-scale adaptive placement |
|
tests. The study aims to evaluate item parameter drift |
|
using empirical data that span four years from the |
|
ACCUPLACER Arithmetic assessment. The results suggest |
|
that the Arithmetic test maintained a reasonably stable |
|
scale in the years 2004 through 2007. The following is |
|
appended: Summary Statistics of Item Exposure Rates |
|
across Years. |
