This manual contains technical information about the ACT® college readiness assessment. The principal purpose of this manual is to document the technical characteristics of the ACT in light of its intended purposes. ACT regularly conducts research as part of the ongoing formative evaluation of its programs. The research is intended to ensure that…

This manual provides guidance and documentation for users of the longitudinal kindergarten-fourth grade (K-4) public-use data file of the Early Childhood Longitudinal Study, Kindergarten Class of 2010-11 (ECLS-K:2011), which includes the first release of the public version of the third-grade data. This manual mainly provides information specific…

One argument against the G index is that, unlike phi, it is not a correlation coefficient; yet, G conforms to the Kendall and E-coefficient definitions. The G index is also equal to the Pearson product moment correlation coefficient obtained from double scoring. (Author/CP)

An alternative derivation was given of Gaylord's formulas showing the relationships among the average item intercorrelation, the average item-test correlation, and test reliability. Certain parallels were also noted in analysis of variance and principal component analysis. (Author)

Reliability maximizing weights are related to theoretically specified true score scaling weights to show a constant relationship that is invariant under separate linear tranformations on each variable in the system. Test theoretic relations should be derived for the most general model available and not for unnecessarily constrained models.…

This paper examines the properties of the Item Efficiency Index proposed by Neill and Jackson (1976; EJ 137 077) for minimum redundancy item analysis. (Author/BW)

Measurement problems which jeopardize the reliability and validity of competency-based writing assessments are analyzed. Methods to stabilize rating criteria and readers' application of them are necessary. Most writing assessment programs use guidelines from norm-referenced test methodology. Use of this method of criteria application based on…

The article presents a protocol for the assessment of prelinguistic intentional communication with young and/or severely language-impaired children. A set of tasks and scoring procedures are presented for the elicitation of proto-declarative and proto-imperative behaviors. Data are presented to support reliability. (Author/CL)

Offers a case study of how one teacher used readability formulas to select the most appropriate materials for her students. Presents 10 suggestions that the teacher followed to avoid being tyrannized by the formulas. (FL)

The objectives of this investigation are to develop, describe, assess, and demonstrate procedures for constructing mastery tests to minimize errors of classification and to maximize decision reliability. The guidelines are based on conditions where item exchangeability is a reasonable assumption and the test constructor can control the number of…

The Early Learning Accomplishment Profile (Early LAP) provides a systematic method for observing children's functioning in the birth to 36-month age range in order to assist teachers, clinicians, and parents in assessing individual skills development in six developmental domains: gross motor, fine motor, cognition, language, self-help, and social…

A closed sequential procedure for estimating true score is proposed for use with answer-until-correct tests. The accuracy of determining true score is the same as in conventional sequential solutions, but the possibility of using an unnecessarily large number of items is eliminated. (Author/CM)

The Florida Teacher Certification Examination was developed as a comprehensive written examination for use in initial teacher certification in the state. Applicants must demonstrate mastery of 23 generic minimum competencies in teaching adopted in Florida statutes and State Board of Education rules. Subtests in General Education cover writing,…

Educators designing procedures for identifying students as learning disabled are faced with serious technical difficulties. A student with a learning disability is one who "has a severe discrepancey between achievement and intellectual ability" in one or more designated areas. The methods of quantifying achievement, intellectual ability,…

The Preliminary Manual for the Portland Problem Behavior Checklist (PPBC) was developed to aid school personnel to identify problem behaviors, and to implement and evaluate intervention procedures to remediate or alter those problem behaviors. This manual describes the development, validation, administration, scoring procedures, and possible uses…
