This paper investigates the differential effectiveness of teachers across student populations, with a focus on gifted and talented (GT) students. Using data from Los Angeles, we estimate teacher effectiveness (proxied by value-added measures (VAMs) of teachers' contributions to student achievement growth) for GT students and examine how they are…

A test battery with two different levels of adaptation is presented: a within-subtest level for the selection of the items in the subtests and a between-subtest level to move from one subtest to the next. The battery runs on a two-level model consisting of a regular response model for each of the subtests extended with a second level for the joint…

Background: Research about the psychometric properties of the Behavioural Appraisal Scales (BAS) in people with profound intellectual and multiple disabilities (PIMD) is limited. This study evaluates invariance in factor structure, item bias and convergent validity of the BAS. Methods: Data on the BAS from two studies (n = 25; n = 52) were…
