With the advent of big data and advances in technology, psychological assessments have become increasingly sophisticated and complex. Nevertheless, traditional psychometric issues concerning the validity, reliability, and measurement bias of such assessments remain fundamental in determining whether score inferences of human attributes are…

One of the areas subsumed under the data-based decision making and accountability practice identified in the National Association of School Psychologists' (NASP) "Model for Integrated School Psychological Services" is to collect information on psychological and educational variables to make decisions at a number of levels of service…

Reliability is a measure of consistency. It is the degree to which student results are the same when they take the same test on different occasions, when different scorers score the same item or task, and when different but equivalent tests are taken at the same time or at different times. Reliability is about making sure that different test forms…

In 2017, the Office of Planning, Research, and Evaluation (OPRE) in the Administration for Children and Families (ACF) funded Mathematica to conduct the Infant and Toddler Teacher and Caregiver Competencies (ITTCC) project. The project aims to examine existing efforts across states, institutions of higher education, professional organizations, and…

The What Works Clearinghouse (WWC) Standards Briefs explain the rules the WWC uses to evaluate the quality of studies for practitioners, researchers, and policymakers. This brief explains what baseline equivalence is and why it matters. As part of the WWC review process for certain types of studies, reviewers assess whether the intervention group…

For children age birth to five, physical, cognitive, linguistic, and social-emotional growth and development occur at a rapid pace. While all children in this age range may not reach developmental milestones (e.g., smiling, saying first words, taking first steps) at the same time, development that does not happen within an expected timeframe can…

No one has a bigger stake in teaching effectiveness than students. Nor are there any better experts on how teaching is experienced by its intended beneficiaries. Only recently have many policymakers and practitioners come to recognize that--when asked the right questions, in the right ways--students can be an important source of information on the…

One of the best methods of formative assessment in academic areas and a method that exemplifies the characteristics of good measures is Curriculum-Based Measurement (CBM; Deno, 1985). Developed at the University of Minnesota in the early 1970's, CBM has been researched in academic areas including mathematics computation, concepts, and…

Describes Minnesota's Preschool Screening program, the first to offer free, voluntary health and developmental screening for state preschoolers, and a related Early Childhood Assessment project to deal with inconsistencies in diagnostic referral rates among school districts. Questions test validity, reliability, and standardization samples and…

This study describes the development of the Active Treatment Client Rights checklist (ATCR), which was designed to facilitate the assessment, monitoring, and implementation of readily observable client active treatment services for adults with developmental disabilities. The ATCR was found to be highly reliable, valid, and useful in enhancing…

Classroom measurement devices, when tailored to fit a teacher's particular instructional objectives, are essential for optimal teaching and learning. Teachers use test data to assess students' progress but often fail to analyze tests for validity. This article shows how locally and correctly developed assessment tools may serve a variety of…

The Infant Monitoring Project is designed to identify infants in need of further evaluation, by having parents complete a set of questionnaires about their infant's development at four-six month intervals. Evaluation of the questionnaires has shown that they are low-cost and have substantial agreement with standardized assessments. (Author/JDD)

The paper describes a self-concept scale specifically designed for use with hearing-impaired adolescents and preadolescents. The "Self-Concept Scale for the Hearing Impaired" is a Likert-type self-report scale using linked verbal and pictorial material, and results in both a global score and a self-concept profile. Validity issues are…

Tests producing results that are used to make important decisions about students, schools, and curricula should not be developed locally by teachers. Although district educators at all levels need to become familiar with measurement nuances, the development of high stakes tests is best left to measurement professionals. Includes four references.…

College students in an introductory psychology course constructed a personality test. They were then asked to administer the test to two students not enrolled in the course and to bring responses to class the following week, at which time they analyzed and discussed the results. (RM)
