Lord, Frederic M. – 1983
If a loss function is available specifying the social cost of an error of measurement in the score on a unidimensional test, an asymptotic method, based on item response theory, is developed for optimal test design for a specified target population of examinees. Since in the real world such loss functions are not available, it is more useful to…

Cantor, Nancy K.; Hoover, H. D. – 1986
This paper isolates and examines separately three distinct sources of error in essay scores: lack of agreement between raters; inconsistencies in performance within mode of discourse, and inconsistencies in performance between modes of discourse. Essay prompts in the Iowa Tests of Basic Skills (ITBS) Writing Supplement were designed to assess…

Linear and equipercentile equating conversions were developed for two forms of the Graduate Record Examinations (GRE) quantitative test and the verbal-plus-quantitative test. From a very large sample of students taking the GRE in October 1981, subpopulations were selected with respect to race, sex, field of study, and level of performance (defined…

Macpherson, Colin R.; Rowley, Glenn L. – 1986
Teacher-made mastery tests were administered in a classroom-sized sample to study their decision consistency. Decision-consistency of criterion-referenced tests is usually defined in terms of the proportion of examinees who are classified in the same way after two test administrations. Single-administration estimates of decision consistency were…
