This paper reports an investigation into the psychometric properties of the COR-Advantage1.5 (COR-Adv1.5) assessment tool, a criterion-referenced observation-based instrument designed to assess the developmental abilities of children from birth through kindergarten. Using data from 8534 children participating in a state-funded preschool program…

Universal screening measures are an integral component of any tiered system of instructional delivery. Recent studies of screening measures have often excluded examinations of bias in predictive validity. The present study examined a common screening instrument for evidence of bias in predictive validity across the four disaggregation categories…

Correlations between predicted averages and actual grades in four universities were compared with those based on current data. A loss on the average of .10 occured in the accuracy of the correlation. The author recommends that prediction studies should not be done every year but on an as-needed basis. (Author)

The use of the regression equation derived from the Anglo-American sample to predict grades of Mexican-American students resulted in overprediction. An examination of the standardized regression weights revealed a significant difference in the weight given to the Scholastic Aptitude Test Mathematics Score. (Author/BB)

A study was conducted at Stark Technical College to compare a normative-referenced test for mathematics placement with a criterion-referenced test that had been used by the college. The study sought to compare statistically the scores of 165 students on the Mathematics Inventory Test (MIT--a criterion-referenced test that had been developed…

The effectiveness of a model for determining a minimal cut-off score for criterion-referenced tests was examined. The model, based upon techniques presented originally by Nedelsky and by Angoff, was first used in conjunction with a multiple choice test developed for use in certifying school counselors in Georgia. A "knowledge estimation panel" was…

Testing with minority and disadvantaged populations in America has resulted in widespread abuse. Theorists have historically viewed tests as instruments for upward mobility in a system in which doors are often opened by parental wealth and status. Predictive validity of tests has not properly accounted for problems in correlational techniques…

In fall 1986, a study was conducted at Florence-Darlington Technical College (South Carolina) to measure the reliability and validity of the TEC-MAT, a newly developed entrance test. The TEC-MAT instrument, a criterion-referenced test consisting of 100 items assessing numerical skills, was field tested among a group of entry-level freshmen already…

A central problem for the user of domain-referenced tests in instruction is deciding who has passed and who has failed. Two procedures were presented and discussed. The first, employing classical test theory, was found to be more useful for larger domains and where the passing standard is 70 percent or less. The sampling procedure suggested by…
