Describes a program system which was developed for the purpose of making estimates about the nature of the distribution of test scores which will result from an administration of a test composed of items of which estimates of item-difficulty and discrimination are available. (Author/RC)

ANALYSIS, a FORTRAN computer program developed as an aid to investigation of and instruction in the psychometric properties of test items, is described. The program utilizes both correlational and analysis of variance approaches to classical item analysis. (Author/JKS)

Measures of consistency and completeness of order relationships derived from test data such as Guttman scales are proposed. The measures are generalized to apply to incomplete data such as data from tailored testing. (Author/JKS)

A set of computer programs, which performs necessary item analysis and related procedures for developing new scales for the Minnesota Multiphasic Personality Inventory, is described. (Author/JKS)

Paper presented at the annual meeting of the National Council on Measurement in Education, Chicago, Illinois, February, 1968.

Microcomputer software for computer-assisted classroom testing is reviewed. The teacher and classroom are emphasized in applying computer technology. The major issues are identification of appropriate classroom testing microcomputer applications; identification of available microcomputer testing software; techniques for software evaluation; and…

This is one of a series of reports on the National Longitudinal Study of Mathematical Abilities (NLSMA). This report is a discussion of many of the programs from the SMSG Computer Program Library as it existed in June, 1972. Major programs included involve item analysis, attitude item analysis, scale scoring, correlation and t-test, stepwise…

The current emphasis on objectives and test item banks for constructing more effective tests is being augmented by increasingly sophisticated computer software. Items can be catalogued in numerous ways for retrieval. The items as well as instructional objectives can be stored and test forms can be selected and printed by the computer. It is also…

This paper will discuss the results of a series of computer simulations comparing the Rasch logistic model to a series of models departing to various degrees from its assumption of equal discrimination power for all items. The results have implications for test construction and test scoring, indicating how closely the conventional raw score…

The New York State Department of Civil Service investigated an empirical application of the Rasch model which appears useful in Civil Service testing. The model is a powerful tool for developing insights into what test items are measuring while permitting the investigator to spot defective items. It also reveals meaningful distinctions in the type…

TESTER, a computer program which produces individualized objective tests from a pool of items, is described. Available in both PL/1 and FORTRAN, TESTER may be executed either interactively or in batch. (Author/JKS)

A method for developing statistically parallel tests based on the analysis of unique item variance was developed. A test population of 907 basic airmen trainees were required to estimate the angle at which an object in a photograph was viewed, selecting from eight possibilities. A FORTRAN program known as VARSEL was used to rank all the test items…

Two methods of item selection were used to select sets of 40 items from a 50-item verbal analogies test, and the resulting item sets were compared for relative efficiency. The BICAL program was used to select the 40 items having the best mean square fit to the one parameter logistic (Rasch) model. The LOGIST program was used to select the 40 items…
