The gold standard in making causal inference on program effects is a randomized trial. Most randomization designs in education randomize classrooms or schools rather than individual students. Such "clustered randomization" designs have one principal drawback: They tend to have limited statistical power or precision. This study aims to…

ACT is often asked whether student scores on the ACT[R] test can be used to make "norm-referenced" or "standards-referenced" comparisons. Norm-referenced interpretations compare students to one another, while standards-referenced interpretations measure student performance against predefined content standards. This brief shows…

The purpose of this research is to provide additional empirical evidence supporting the use of both a multidimensional profile and an overall evaluation of teaching effectiveness as valid indicators of student perceptions of effective classroom instruction. A factor analytic teaching evaluation instrument was used that also included open-ended…

The ECTS grade transfer scale is an interface grade scale to help European universities, students and employers to understand the level of student achievement. Hence, the ECTS scale can be seen as an interface, transforming local scales to a common system where A-E denote passing grades. By definition, ECTS should distribute the passing students…

This article reviews issues involved with using norm-referenced measures within an intervention validity model. Methodological examination of intervention validity has become more important as intervention methodologies have become part of federal legislation. However, current practice and federal guidelines often implicitly portray a dichotomy…

Professional educators as goal formulators are presented as the responsible agents of accountability. Norm- and criterion-referenced testing are compared and suggestions for accountability and goal development are given. (RAO)

Discusses advantages and disadvantages of norm-referenced and criterion-referenced tests. (JF)

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…

This paper is a historical and critical analysis of changes in features of educationalisation focusing on how educationalisation has been characterised over time by a peculiar interweaving of knowledge and social reform. The history of the American Social Science Association provides a backdrop; drawing on the theories of Deleuze, this paper…

We developed equivalent, alternate forms of easyCBM[R] in reading (n=20 forms) and mathematics (n=13 forms) with different skills reflective of the National Reading Panel (NRP) and the National Council of Teachers of Mathematics (NCTM), respectively. We then took three forms to use as screening measures in the fall, winter, and spring so educators…

Research Findings: We examined the reliability and validity of the language, literacy, and mathematics domains of "Work Sampling for Head Start" (WSHS), an observational assessment designed for 3- and 4-year-olds. Participants included 112 children who were enrolled over a two-year period in Head Start and a number of other programs…

A study involving a sample of people selected to represent the nonimpaired American population, aged 16 to 74 years, was undertaken to determine the effectiveness of the Wechsler Memory Scale--Revised. The scale's subtests were designed to assess memory of personal and general knowledge, logical memory, verbal paired association, figural memory,…

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…

Normative data can help those who must interpret test results decide whether a given performance on a criterion-referenced test is satisfactory. (Author/IRT)
