Using grade 3 and 8 math and English state assessment data, in this paper we focus on time used for testing…

The article reports three simulation studies conducted to find out whether the effect of a time limit for testing impairs model fit in investigations of structural validity, whether the representation of the assumed source of the effect prevents impairment of model fit and whether it is possible to identify and discriminate this method effect from…

Speeded tests set time limits so that few examinees can reach all items, and power tests allow most test-takers sufficient time to attempt all items. Educational achievement tests are sometimes described as "timed power tests" because the amount of time provided is intended to allow nearly all students to complete the test, yet this…

Current taxonomies of intelligence comprise two factors of mental speed, clerical speed (Gs), and elementary cognitive speed (Gt). Both originated from different research traditions and are conceptualized as dissociable constructs in current taxonomies. However, previous research suggests that tasks of one category can be transferred into the…

New Meridian Corporation has developed the "Quality Testing Standards and Criteria for Comparability Claims" (QTS) to provide guidance to states that are interested in including New Meridian content and would like to either keep reporting scores on the New Meridian Scale or use the New Meridian performance levels; that is, the state…
