The authors describe the significant contributions of Robert Ebel to educational measurement theory and its applications. A biographical sketch details Ebel's roots and professional resume. His influence on classroom assessment views and procedures are explored. Classic publications associated with validity, reliability, and score interpretation are described in terms of their contributions to the field and their relevance to current practice. An analysis of the diversity of Ebel's contributions over his career projects a model of "psychometric statesman" for contemporary measurement specialists to emulate.

The author takes the position that many of the fundamental measurement concepts and relationships often are used in our written communications in ways that demonstrate misunderstanding and lead to confusion. Illustrations of the misuses are provided, anecdotes and speculation about the implications are offered, and suggestions for addressing the problem are presented.

Presents a broad definition of "testlet" and suggests a framework for classifying types of testlets. Considers several issues that bear on the conceptualization of testlets and analyses of scores from tests composed of testlets. Suggests some research topics that seem particularly important to advancing the meaningful and appropriate use of testlets. (SLD)

This paper assists teachers in developing grading practices that communicate students' achievements to their parents effectively and fairly. A teacher's personal grading philosophy must be considered in developing a personal plan. Procedural steps in establishing a plan are outlined, and the features of several common methods are compared. (SLD)

Literature related to the multiple true-false (MTF) item format is reviewed. Each answer cluster of a MTF item may have several true items and the correctness of each is judged independently. MTF tests appear efficient and reliable, although they are a bit harder than multiple choice items for examinees. (SLD)

This National Council on Measurement in Education (NCME) module is designed to help teachers understand test reliability requirements. Focus is on the reliability of scores from teacher-made achievement tests used for interpreting norm-referenced scores. Reliability, factors affecting scores, reliability estimation methods, reliability's relation to score use, factors related to testing, and alternatives when scores are unreliable are explained.

Representatives of the Riverside Publishing Company discuss the "Lake Wobegon Phenomenon," the reported "above average" achievement of most elementary schools nationwide that was discussed by J. J. Cannell (1988) of the Friends for Education. More appropriate use of normative comparisons and more complete reporting of test results should resolve the apparent paradox. (SLD)

This paper demonstrates how an analysis of the "Standards for Educational and Psychological Testing" (1985) can define the body of knowledge needed by teachers for the effective use of tests in classroom instruction. Procedures are described for identifying standards relevant to teachers' roles and their behavior. (SLD)
