This report examines the differences in impact estimates and standard errors that arise when these are derived using state achievement tests only (as pre-tests and post-tests), study-administered tests only, or some combination of state- and study-administered tests. State tests may yield different evaluation results relative to a test that is…

Cypress, Beulah K. – 1973
The potential of the Rasch model to develop scores, on a ratio scale, suitable for interindividual comparisons, from intact groups with disparate distribution characteristics was investigated. The specific problems studied were: (1) the effects of skewed test score distributions on the ability parameter of the Rasch measurement model; (2) the…

Stroud, T. W. F. – 1973
In a multiple (or multivariate) regression model where the predictors are subject to errors of measurement with a known variance-covariance structure, two-sample hypotheses are formulated for (i) equality of regressions on true scores and (ii) equality of residual variance (or covariance matrices) after regression on true scores. The hypotheses…

Hendrickson, Leslie; Jones, Barnie – 1982
The logic of using a gain score approach versus longitudinal causal models is studied in this secondary analysis of a complex data base. The gain score model used by the Federal Reserve Bank and the School District of Philadelphia in their "What Works in Reading?" study is successively refined using the LISREL structural equation…

Scott, Leslie A.; And Others – 1995
This report describes the growth in cognitive skills and achievement, and the continuities and discontinuities experienced in school and at home by the eighth-grade cohort of the National Education Longitudinal Study of 1988 (NELS:88) during the 2 years between the study's base year (1988) and the first-followup (1990) surveys. The report examines…
