A relatively simple method is developed to obtain confidence intervals for a student's proportion of domain mastery in criterion-referenced or mastery measurement situations. The method uses the binomial distribution as a model for the student's scores under hypothetically repeated assessments, and it makes use of widely available "F"…

Two types of test scores are often used for determining eligibility for early intervention services: standard scores and developmental-age scores. Because they are derived using different methods, these two types of scores do not provide equivalent information. Characteristics of norm-referenced and criterion-referenced tests and the scores…

Increasingly, academic institutions are being required to improve the validity of the assessment process; unfortunately, often this is at the expense of reliability. In medical schools (such as Leeds), standardized tests of clinical skills, such as "Objective Structured Clinical Examinations" (OSCEs) are widely used to assess clinical…

There is increasing pressure for institutions of higher education in the United States to objectively document student learning outcomes. Criticism of higher education is mounting, with the result being that education institutions need to be more accountable for student learning on their campuses. As a result, there is increased interest in the…

The comparability of examinations in different subjects has been a controversial topic for many years and a number of criticisms have been made of statistical approaches to estimating the "difficulties" of achieving particular grades in different subjects. This paper argues that if comparability is understood in terms of a linking…

The No Child Left Behind Act and the accountability movement in public education caused many states to develop criterion-referenced academic achievement tests. Scores from these tests are often used to make high stakes decisions. Even so, these tests typically do not receive independent psychometric scrutiny. We evaluated the 2005 Arkansas…

In educational testing, subscores may be provided based on a portion of the items from a larger test. One consideration in evaluation of such subscores is their ability to predict a criterion score. Two limitations on prediction exist. The first, which is well known, is that the coefficient of determination for linear prediction of the criterion…

In 2005, the undergraduate advisory committee at the University of Toronto Mississauga found that across all disciplines, writing proficiency was the skill weakness that generated the greatest concern. Students reported that they often found writing tasks intimidating, and suggested that effective feedback and guidance would improve their writing.…

This article attempts to present a novel application of a method of measuring accuracy for academic success predictors that could be used as a standard. This procedure is known as the receiver operating characteristic (ROC) curve, which comes from statistical decision techniques. The statistical prediction techniques provide predictor models and…

The study investigated the feasibility of adapting the coefficient k introduced by Cohen (1960) and elaborated by Swaminathan, Hambleton, and Algina (1974) to an internal consistency estimate for criterion referenced tests in single test administrations. The authors proposed the use of k as an internal consistency estimate by logically dividing…

Single-administration procedures for estimating the coefficient of agreement, a reliability index for criterion referenced tests, were recently developed by Subkoviak. The procedures require a distributional assumption for errors of measurement and an estimate of each examinee's true score. A computer simulation of tests composed of items that…

This study examined the effectiveness of two different domain definition strategies in achieving homogeneity of criterion-referenced test items. The argument was tested regarding the extent to which item writers following the Instructional Objectives Exchange (IOX) domain definition strategy for a cognitive skill generate items that are more…

A framework, or classification scheme, is provided for displaying the spectrum of criterion-referenced tests. This framework illustrates that no single type of test can be identified as the absolute prototype criterion-referenced test. It is shown that over the past 115 years criterion-referenced testing has grown to be a many-faceted concept, its…

Teachers should be evaluated chiefly by the results they produce. Those results will not be properly detected through the use of norm-referenced achievement tests (NRT) due to the following major deficits of NRT: (1) the descriptions of what is measured by NRT are far too loose; (2) evaluative expectations are unclear; (3) the necessity for NRT to…
