Reading proficiency is arguably the most important academic skill needed for school success. Students who fail to acquire basic reading skills in primary grades fall further behind their peers in intermediate and later grades. Despite national efforts to improve academic outcomes for all students, a recent national report in reading (National Center for Education Statistics, 2011) shows that 51% of African American, 49% of Hispanic, and 53% of Native American fourth-grade students were reading below basic levels. Included in this diverse group are students who speak a primary language other than English, commonly referred to as English Language Learners (ELLs). Although the need for early identification, systematic, and intensive intervention for struggling readers has been established (Lane, Menzies, Munton, Von Duering, & English, 2005), early interventions for at-risk students are underrepresented in the literature. For the purpose of this study, the term at risk was used to describe students from culturally and linguistically diverse groups performing below grade level on measures of early reading skills.Sight words, also referred to as high-frequency words, constitute a sizable portion of the text students encounter in reading. Many of these words do not conform to phonetic rules. Instruction in sight words not only can result in a corresponding increase in reading fluency and comprehension (Fuchs, Fuchs, Hosp, & Jenkins, 2001) but also can improve students' confidence levels and reduce their frustration with reading (Bliss, Skinner, & Adams, 2006). Efforts to identify effective sight word reading interventions for at-risk students have included peer tutoring interventions (e.g.,
