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…

The AVANCE Head Start program provides comprehensive early childhood education and family support services to low-income families with children 3 to 5 years of age. One of the main purposes of Head Start is to help children from low-income backgrounds succeed in kindergarten and beyond. This report examines the academic performance of AVANCE…

The provision of high-quality early mathematics instruction and intervention is critical to ensure that all students are on track for academic success. Given this, identifying and utilizing assessments that can enable the detection of nonresponse to mathematics instruction is a critical aspect of early intervention. To this end, the current study…

The current study contributes empirical data to our understanding of how knowledge of American Sign Language (ASL) syntax aids reading print English for deaf children who are bilingual and bimodal in ASL and English print. The first analysis, a conceptual replication of Hoffmeister (2000), showed that performance on the American Sign Language…

This study used a randomized controlled trial design to investigate the ROOTS curriculum, a 50-lesson kindergarten mathematics intervention. Ten ROOTS-eligible students per classroom (n = 60) were randomly assigned to one of three conditions: a ROOTS five-student group, a ROOTS two-student group, and a no-treatment control group. Two primary…

Abydos is a professional development program that includes a three-week writing institute. It provides school districts with teachers who, after a year of implementation and another year of professional development, can train other teachers, thus providing ongoing staff development. The Houston Independent School District (HISD) implemented Abydos…

The assessment of screening accuracy and setting of cut points for a universal screener have traditionally been evaluated using logistic regression analysis. This analytic technique has been frequently used to evaluate the trade-offs in correct classification with misidentification of individuals who are at risk of performing poorly on a later…

The Texas Education Code (§ 29.051) requires school districts to provide every language minority student with the opportunity to participate in either a bilingual or English as a second language (ESL) program. This evaluation report summarizes the performance of students who participated in the district's Dual Language Bilingual Program. Included…

Houston Independent School District (HISD) has provided prekindergarten classes for Houston area four-year old students since the 1985-1986 academic year. The focus of the program is on lifelong learning to enhance the physical, emotional, and social wellbeing of the whole child and provide the foundational skills required for career and college…

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.…

In this study, the authors assessed the contribution of engagement (on-task behavior) to the mathematics problem-solving performance of seventh-grade students after accounting for prior mathematics achievement. A subsample of seventh-grade students in four mathematics classrooms (one high-, two average-, and one low-achieving) from a larger…

In a large school district in Florida, many third-grade students have been retained over a 7-year period. Enrollment documents, such as summer school registration forms and seven annual summer reading camp evaluations in 2013-2019, indicated that 13,693 students attended the 4-week summer reading camp during this period. Summer reading camps are…

The authors' purpose was to explore the effects of a supplementary, guided, silent reading intervention with 80 struggling third-grade readers who were retained at grade level as a result of poor performance on the reading portion of a criterion referenced state assessment. The students were distributed in 11 elementary schools in a large, urban…
