This article considers psychometric properties of composite raw scores and transformed scale scores on mixed-format tests that consist of a mixture of multiple-choice and free-response items. Test scores on several mixed-format tests are evaluated with respect to conditional and overall standard errors of measurement, score reliability, and…

Smoothing techniques are designed to improve the accuracy of equating functions. The main purpose of this study is to compare seven model selection strategies for choosing the smoothing parameter (C) for polynomial loglinear presmoothing and one procedure for model selection in cubic spline postsmoothing for mixed-format pseudo tests under the…

This study examines the effectiveness of three approaches for maintaining equivalent performance standards across test forms with small samples: (1) common-item equating, (2) resetting the standard, and (3) rescaling the standard. Rescaling the standard (i.e., applying common-item equating methodology to standard setting ratings to account for…

The goal of this study was the development of a procedure to predict the equating error associated with the long-term equating method of Tate (2003) for mixed-format tests. An expression for the determination of the error of an equating based on multiple links using the error for the component links was derived and illustrated with simulated data.…

Answer keys for physician and teacher licensing examinations were studied. The impact of variability on total errors of measurement was examined for answer keys constructed using the aggregate method. Results indicated that, in some cases, scorers contributed to a sizable reduction in measurement error. (Author/GDC)

Using three different forms of a 61-item administrator/supervisor questionnaire, the effects of both order and grouping were examined in separate analyses. For low-inference type items, factor structures obtained from survey data appear to be affected by item order, and, to a lesser extent, by grouping items. (Author/PN)
