Population changes, legislative changes, time and cost constraints, and practitioner and family perceptions each affect the delivery of early intervention services. This pilot project examined current evaluation practices used with the birth to 3 population. The role of norm-referenced and authentic assessment tools in the eligibility…

Some basic statistical concepts relevant to the teacher--mean scores, standard deviation, normal and skewed distributions, z scores, item analysis, standard error of measurement, reliability--and their use by the teacher are explained. (RM)

The internal validity of the RMC models, especially Model A, is examined. Concern centers on limiting evaluation to cognitive outcomes, using constant percentile as the no-treatment expectation, and using norms for one test to establish the expected no-treatment performance level for another test. (MH)

Development of new scales from test items usually requires several hundred cases in each of the defined groups. Application of multivariate techniques to existing test scales also encounters such problems as multicolinearity, combining ipsative with normative measures and ordinal with equal interval scales, differential prediction, and…

An experiment was performed to evaluate the tenability of the assumption in the Elementary Secondary Education Act (ESEA) Title I proposed variance estimation procedures for criterion referenced tests. The assumption is that the ratio of the local to the national standard deviation for the national sample will be the same for the normed test as…

The role that measurement error plays in the regression effect is discussed with particular reference to the RMC models for evaluating the effects of Elementary Secondary Education Act Title I programs. The norm referenced evaluation model assumes a theory of growth where the relative ranking of students remains the same from pretest to posttest…

The norm-referenced evaluation model (RMC Model A) for Title I project evaluation, consists of procedures whereby the expected posttest standing of a treatment group under the null condition is generated from their pretest standing. It is assumed that the treatment group is not selected on the basis of their pretest scores and can be considered…

This paper examines the development and evaluation of criterion-referenced measures, and elaborates on the distinction between them and norm-referenced measures. The concept of sensitivity is introduced as an appropriate method for evaluating such measures, and a sensitivity index is proposed. The traditional model for the response of a subject to…

This text on the assessment of students with disabilities focuses on accuracy in assessment and testing and the need for functional and meaningful assessment practices. The 14 chapters are grouped into 4 major parts. The first part, "An Introduction to Assessment," describes a comprehensive evaluation and discusses the mandatory…

Project Information Packages (PIPs), kits containing directions for the replication of exemplary remedial programs, were field tested in a number of school districts. Based on curriculum analysis and site visits PIPs were found to induce projects which were adequate copies of what was packaged; however, what was packaged was not sufficient to…
