The Effect of Anchor Test Construction on Scale Drift
Antal, Judit; Melican, Gerald; Proctor, Thomas; Wiley, Andrew
College Board, Slides presented at the Annual Meeting of the National Council on Measurement in Education (NCME) (Denver, CO, Apr 3, 2010)
Presented at the Annual Meeting of National Council on Measurement in Education (NCME) in 2010. The focus of the research is to investigate the effect of applying the Sinharay & Holland (2007) midi-test idea for building anchor tests to an on-going testing program with a series of versions of the test and comparing these results to the more commonly applied miniature anchor test assembly method. Overall, the results of our study support the proposal by Sinharay and Holland under very strict item and simulee generation method as the amount and degree of equating error observed did not appear to be significantly impacted by the change in the anchor test characteristics.
