A Descriptive Analysis of Test Session Observation Checklist Ratings From the Woodcock Johnson III Standardization Sample

Modern scale construction techniques have been used to develop scales measuring examiner ratings of examinees’ test session behavior (TSB) on Wechsler and Stanford-Binet intelligence tests. This study analyzes data from the Test Session Observation Checklist (TSOC), a measure developed by post hoc rational analysis, from a portion of the Woodcock Johnson Psychoeducational Battery-Third Edition standardization sample (N = 5,769). Results indicate (a) most participants are rated as displaying minimal negative test session behaviors, (b) the seven TSOC items are organized into two components (General Impressions and Attention To Task) that explain roughly 54% of the variance in TSOC scores, and (c) race, sex, and age differences in component scores examined with and without covariates are consistent with results from prior TSB research.
