How prevalent is dyslexia? A definitive answer to this question has been elusive because of the continuous distribution of reading performance and predictors of dyslexia and because of the heterogeneous nature of samples of poor readers. Samples of poor readers are a mixture of individuals whose reading is consistent with or expected based on…

Assessing students' emerging literacy skills is crucial for identifying areas where a child may be falling behind and can lead directly to an increased chance of reading success. The Waterford Assessment of Core Skills (WACS), a computerized adaptive test of early literacy for students in prekindergarten through 2nd grade, addresses this need.…

The Houston Independent School District offers two primary bilingual programs for Spanish-speaking English-language learners (ELLs). In both programs, students may transition into a pre-exit phase of bilingual education so long as they meet certain performance criteria. In this Pre-Exit phase, predominantly English-language instruction is used in…

The State Compensatory Education (SCE) program is designed to reduce dropout rates and increase academic performance of students identified as being at-risk of dropping out of school. SCE operates as a funding source to supplement instructional services and offer academic support to students who meet the SCE at-risk criteria established by the…

This study hypothesized that HISD prekindergarten participation consistently correlated with better educational outcomes for students. Taking into account students' age differences through kindergarten enrollment, propensity score matching controlled for students' background characteristics. Three cohorts of students in this study were eligible or…

Best practice in gifted and talented identification procedures involves making decisions on the basis of multiple measures. However, very little research has investigated the impact of different methods of combining multiple measures. This article examines the consequences of the conjunctive ("and"), disjunctive/complementary…

States are increasingly interested in including measures of student achievement growth, or "value- added," in evaluating teachers. Annual state assessments, however, which are the typical measure of student growth, usually cover only reading and math teachers and only in grades 4-8. These state assessments thus cannot …

States and school districts are exploring alternatives to state tests for measuring teachers' contributions to student learning. One approach applies statistical value-added methods to alternative student assessments such as commercially available tests and end-of course tests. The evidence suggests that these methods can reliably distinguish…

Over the past few decades, reading assessment has been pushed to the forefront of the national discussion about education. The most recent reauthorizations of the Elementary and Secondary Education Act (1994, 2001) made assessment a priority as administrators and teachers are attempting to meet increasing accountability standards, but measuring…

Independent schools are, for the most part, exempt from mandatory participation in standardized tests designed for state and federal comparisons, nor are they required to take part in comparative international assessments. The anxiety in the broader culture, however, is driving a growing interest among independent school parents (and prospective…

April 1987 marked the seventh year of the statewide testing program in reading, language, and mathematics mandated by the Arizona State legislature. The Arizona testing program used nationally-standardized norm-referenced achievement tests. The Iowa Tests of Basic Skills (ITBS) were administered to students in grades 1 through 8, the Stanford…

Validity and reliability issues in standardized testing of students of limited English proficiency (LEP) were studied. Existing data from four different school sites were obtained for LEP and non-LEP students for three different standardized tests, the Stanford Achievement Tests (Ninth edition), the Iowa Tests of Basic Skills, and the Language…

The SuccessMaker[R] program is a set of computer-based courses used to supplement regular classroom reading instruction in grades K-8. Using adaptive lessons tailored to a student's reading level, SuccessMaker[R] aims to improve understanding in areas such as phonological awareness, phonics, fluency, vocabulary, comprehension, and concepts of…

This paper argues that the standard "When it is expected that a test will be used to make norm-referenced assessments of groups rather than individuals, normative data based on appropriate group statistics should be provided," which was considered secondary in the 1985 "Standards for Educational and Psychological Testing" and…

1988 is the eighth year of the Arizona Pupil Achievement Testing Program which is administered to fulfill the requirements of Arizona Revised Statutes Section 15-741 through Section 15-744. This legislation mandates that a nationally standardized norm-referenced achievement test be administered during April to all pupils enrolled in Arizona public…
