Purpose: Standardized tests are one of the primary assessment tools used by speech-language pathologists (SLPs) to diagnose child language impairment. Numerous child language tests are commercially available; however, it is unknown what factors lead clinicians to select particular tests to use in clinical practice. This study investigated whether…

The study investigated the extent to which information obtained from the WISC overlaps with information obtained from the ITPA. A canonical correlation analysis revealed that only 24 percent of the WISC subtest variance is redundant, given the ITPA; while 22 percent of the ITPA subtest variance is redundant, given the WISC.

A procedure is proposed for determining whether correlations obtained between two measures justify the assumption that the measures are identical. It is intended especially for small samples. In the example, the performance scales of two intelligence tests were administered to 32 deaf adolescents. (GDC)

This study was concerned with determining the validity of the Slosson Intelligence Test (SIT) using the Stanford-Binet Intelligence Scale (S-B), Form L-M as the validity criterion. The sample consisted of 724 students enrolled in 10 public school systems in northeastern Massachusetts. Using the Pearson-Product Moment formula a coefficient of…

A procedure for in-depth analysis of a limited number of tests being considered for selection by a school, district, project, or state personnel is described. This procedure involves listing the objectives that it would be desirable to measure determining the relative importance of each of these objectives, having "judges" match test items to…

A study supplementing earlier research by Lalande and Schweckendiek investigated comparisons and correlations obtained from testing a group of 17 university students of German using both the American Council on the Teaching of Foreign Languages (ACTFL) Oral Proficiency Interview (OPI) and the most recent revision of the examination for the…

An objective-based classification of needs-assessment areas for elementary education and a critical test evaluation procedure for application to measurement devices in these need areas were developed. Criteria for the evaluation are measurement validity, examinee appropriateness, administrative usability, and normed technical excellence. The…

An analysis was made of quality ratings of elementary level standardized tests. Applying multidimensional scaling to intercorrelations of quality ratings, it was found that the criterion of content and construct validity was a central element in the evaluation of elementary tests. In addition, several types of validity and reliability were found…

A study was conducted at Cuyahoga Community College to test the relationship between student scores on timed and untimed reading comprehension and vocabulary tests, and to investigate the relationship between those scores and intelligence. The study sample included 72 students enrolled in classes at developmental, freshman, and sophomore levels.…

Developmental psychologists have not traditionally documented the psychometric properties of their observational instruments, partly because such concepts as reliability and validity are associated mainly with paper-and-pencil tests. A multitrait-multimethod correlation matrix (MTMM) was presented as a useful method for the psychometric evaluation…
