Significant growth in the number of English language learners (ELLs) in U.S. schools is anticipated to continue, demanding that educators and evaluators have the skills necessary to distinguishing language difference from disability and provide appropriate services to these students. However, little research exists examining the role of evaluator's cultural competence in evaluating ELLs for special education; furthermore, what does exist shows that many evaluators report low levels of self-efficacy as it relates to assessing ELLs. The first chapter of the dissertation reports on a review of 21 articles conducted to address best practices for evaluating culturally and linguistically diverse (CLD) learners, evaluator self-efficacy, and recommendations for conducting culturally competent assessments and evaluations. The majority of the articles identified in this review focused on recommendations for best practices for conducting evaluations rather than reporting empirical findings related to the topic. Only one study was identified that focused on appropriate training needed by evaluation staff to effectively discriminate between language difference and a disability. Based on the findings of this review, additional research, using a rigorous methodology is needed. Addressing that need, the second chapter reports the results of a study conducted to examine the effectiveness of Project PEAC3E (Preparing Evaluators to Accurately Conduct Culturally Competent Evaluations), a reform-oriented professional development model, using case-based activities designed to increase evaluators' sense of self-efficacy, cultural competence, and the accuracy of evaluator eligibility decisions for English language learners (ELLs). The study found that Project PEAC3E was effective in increasing evaluator self-efficacy.

This study was designed to provide information on the reading instructional practices of 36 first grade teachers in nine schools that serve predominantly Spanish-speaking and ELL students in a southeastern U.S. school district. The purpose of this investigation was to describe teaching practices employed during English language arts instruction and to examine their use in relation to instructional grouping strategies, teacher language use, and student engagement. Participating classrooms were observed three times throughout the 2006-07 school year. Data were collected via the Timed Observations of Student Engagement/Language (TO/SEL) classroom observation instrument (Foorman & Schatchneider, 2003). Paired sample t-tests, multivariate analyses of variance (MANOVA), and multiple regression analyses were employed to investigate the relationship among the following observed variables: allocation of reading instructional time, grouping strategies, teacher language use and student engagement. Several key findings emerged. Participating teachers spent a greater amount of time on meaning-focused reading instruction (i.e., writing, reading texts, reading comprehension) than on code-focused reading instruction (i.e., word work, spelling, reading fluency, phonemic awareness), both during all four observed grouping strategies and after controlling for individual student seat work. In addition, of five key collapsed instructional variables (word work/spelling, oral language, writing, reading texts, and reading comprehension), teachers spent most time on word work/spelling (19%) and writing (18%). Reading texts and reading comprehension instruction together comprised 26% of total instructional time. Whole class instruction was the grouping strategy of choice among teachers (65% of total observed time); in sharp contrast, teachers spent 11% of observed time engaged in small group instruction, despite research findings supporting the effectiveness of sound grouping instruction. In addition, as little as 1% of teachers' total instructional time was spent in oral language/discussion, and 6% of total instructional time was spent in vocabulary instruction. The results also demonstrated little variation in teacher language use. Thus, evidence of "codeswitching" was not significant. Student engagement was high- 91% of total time students were observed; and was highest during writing and word work/spelling instruction. More longitudinal research is warranted that further explores precisely documented teacher reading instructional practices in relation to student outcomes with culturally and linguistically diverse student populations. Implications for practice include teacher training and professional development on managing small group instruction, and incorporating additional oral language/discussion, vocabulary and meaningful tasks into daily classroom activities.
