The purpose of this evaluation was to examine the impact of i-Ready Personalized Instruction on reading achievement, as measured by SBA scores. We compared students in schools using i-Ready Personalized Instruction school-wide (Treatment students) to students who only received i-Ready Diagnostic assessments and who were in schools only partially…

Language must be taught with academic vocabulary that is meaningful and that can be transferred between content and context. This comparative-descriptive research study examines how academic specific instruction increases students' learning of a second language acquisition (i.e., English). The conceptual framework of the study drew research…

Oral reading fluency (ORF) has been widely used as a measure of students' overall reading competency. However, accuracy, or words correct per minute (wcpm), derived from ORF testing may not reveal all aspects of a student's reading abilities. The present study investigated the oral reading miscue patterns of students with and without learning…

We explored the usefulness of first and second grade reading measures and responsiveness criteria collected within a response-to-intervention (RtI) framework for predicting reading disability (RD) in third grade. We used existing data from 387 linguistically diverse students who had participated in a longitudinal RtI study. Model-based predictors…

This study examined the predictive validity of curriculum-based measures in reading for Spanish-speaking English learners (ELs) at various levels of English proficiency. Third-grade Spanish-speaking EL students were screened during the fall using DIBELS Oral Reading Fluency (DORF) and Daze. Predictive validity was examined in relation to spring…

In this technical report, we describe a study examining the internal structures of the easyCBM reading measures, Grades K-5. Data were gathered from a convenience sample of 114 Kindergarten students, 43 first graders, 82 second graders, 100 third graders, 109 fourth graders, and 71 fifth graders attending schools in Oregon, Georgia, South…

The use of oral reading fluency (ORF) passages within a Response to Intervention (RTI) framework is examined. Significant limitations within the current ORF research are discussed. The passage equivalency and readability scores for DIBELS Next, AIMSweb, and a school district's curriculum's ORF passages are evaluated using Generalizability Theory…

State and local assessment data from 117 students in one school in the California Central Valley were examined to determine how much participation in a kindergarten through second grade multitiered reading intervention model contributed to third grade reading achievement, over and above the demographic factors of ethnicity, socioeconomic status,…

This study investigates the question of test bias to develop an index of the appropriateness of a test to a particular socioeconomic or racial-ethnic group. Bias is defined as an item by race interaction in an analysis-of-variance design. The sample of 172 third graders at two integrated schools in a large California school district, included 26…

California law requires that the reading performance of children in selected grades throughout the state be tested. Since wide variations exist among California school districts in geographical, social, financial, and many other conditions, information related to many of these conditions in which pupils are learning to read is reported, thus…

Presented are findings from California's State testing program for 1971-72 and 1972-73. The factors (variables) examined were divided into two groups: output factors, indicators of school quality such as scores on achievement tests; and input factors, factors describing the characteristics of school districts such as class size, tax rate, etc.…

The factors (variables) examined in the California State Testing Program were divided into two groups for the analyses: (1) the 11 indicators of school quality in terms of the products of the educational system, referred to as output factors (e.g., pupil scores on achievement tests); and (2) the 22 indicators of school quality in terms of the…
