The 2014 Michigan Public High School Context and Performance Report Card is the Mackinac Center's second effort to measure high school performance. The first high school assessment was published in 2012, followed by the Center's 2013 elementary and middle school report card, which used a similar methodology to evaluate school performance. The…

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…

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…

Scores on the Wechsler Intelligence Scale for Children-Revised (WISC-R) and Wechsler Adult Intelligence Scale-Revised (WAIS-R) Verbal, Performance, and Full Scales were compared for 26 adolescents with educable mental handicaps. The WAIS-R, while strongly correlated with the WISC-R, provided higher scores on all three scales. Several WISC-R…

The extent to which national performance on an achievement test battery changed over a 4-year period was studied, and the comparative performance of students in school districts taking the test series for the first time was compared with that of students in districts that had used the battery at least once in one or more grades. The seventh…
