CEA Project News: Professor Keller to research anchor items with CTB/McGraw-Hill
Assistant Professor Lisa A. Keller of UMass was recently awarded a research contract with
CTB/McGraw-Hill to study the appropriate course of action to take when items
that are used in equating exhibit differential functioning across
administrations. To that end, different
methods for detecting aberrant items will be explored, and criteria used for
determining when it may be best to delete the item from the equating will be
established. The criteria for evaluation will be dependent upon effect that
deleting the item or retaining the item has on the classification of examinees
and the determination of AYP. This is a one-year grant, funded by
CTB/McGraw-Hill for approximately $56,000, with Professor Keller and CTB's Karla
Egan (a UMass alumna) as co-principal investigators.
