The 2014 Michigan Public High School Context and Performance Report Card is the Mackinac Center's second effort to measure high school performance.

Assessing a high school's effectiveness is not straightforward. Comparing a school's standardized test scores to those of other schools is one approach to measuring effectiveness, but a major objection to this method is that students' test scores tend to be related to students' "socioeconomic" status--family household income, for…

Psychometric practice does not always converge with the advances of psychometric theory. In order to investigate this gap, the authors focus on the 10 most used psychological tests in Europe, as identified by recent surveys. The article analyzes test manuals published in 6 different European countries for these 10 most used tests. A total of 32…

Compared the standard scores and age scores obtained from the Peabody Picture Vocabulary Test (PPVT)(1965) and the Revised Peabody Picture Vocabulary Test (PPVT-R)(1981) with (N=88) preschool children. Results found the mean PPVT IQ and Mental Age scores were significantly higher. Discusses implications for using the PPVT-R. (Author)

While there was a refining of this original sample in 1957, no contemporary standards for normal people have been published.

The process of determining test norms and of using them realistically is discussed. This process involves putting meaning into a single test score by relating it to other test scores achieved by other pupils or by the same pupil at other times. The focus of attention is on the meaning of test norms; it is not on the meaning of types of test…

Finds further evidence of the close equivalence of scores derived from the Wechsler Intelligence Scale for Children (Revised) and the Stanford-Binet, but fails to support the practice of computing adjusted mental age scores. Subjects were (N=25) children in the bright normal range of intelligence. (JAC)

The factor structure of a new co-normed cognitive and achievement battery for children, the Differential Ability Scales (DAS) was investigated. The DAS was factor analyzed in conjunction with the Peabody Picture Vocabulary Test-Revised (PPVT-R), and the composite score of the Iowa Test of Basic Skills (ITBS). Subjects were 56 six- to…
