Contemporary research suggests that multiple criteria, including SES, ethnicity, first and second language proficiency levels, language dominance, immigrant and/or generational status, acculturation status, and educational placement history predict ELL student achievement levels (Abedi, 2008). However, the majority of states do not examine these factors and instead use a combination of the Home Language Survey (HLS) plus an English language proficiency test for screening and identification, though it is debated if these instruments adequately measure the type of language proficiency needed to be successful in mainstream classrooms (O'Malley & Pierce, 1994). Because of these findings, it seems that multiple criteria are important to examine when screening students for English Language Learner (ELL) placement. It is hypothesized that a more detailed classification system will better predict students' academic language abilities as part of a universal screening effort, and truly identify those at most need for specialized language support. The present study uses a correlational design to examine the relationship between a parent interview form, the Bilingual Parent Interview (BPI) and students' language proficiency scores in both their native and second languages, as well as their academic achievement. It was hypothesized that the multiple criteria assessed with the BPI would be more associated with language proficiency abilities and academic achievement than the HLS. English-Language Learners (ELLs; n= 42) in grades two through five were targeted for participation. Families were recruited from a public elementary school in a city in Southern California. Record reviews were conducted to collect parents' responses on the HLS and the BPI, as well as students' language proficiency scores on the California English Language Development Test (CELDT), the Language Assessment Scales Links Español, and the Preschool Language Assessment Scales 2000 Español 2000 (Pre-LAS 2000). In addition, students' academic achievement based upon the California STAR program was also collected. It was anticipated that items on the BPI would better correlate students' language abilities and academic achievement than those from the HLS. However, it was determined that the HLS better correlated with measures of English Language Proficiency and Spanish Language Proficiency, therefore providing initial support for the validity of this measure. Examination of the socio-cultural factors related to the language abilities and academic outcomes of at-risk ELL students expands upon efforts to identify students in need of remedial support as part of an early prevention model. In addition, the assessment of language proficiency and achievement data in both English and Spanish extends the effort to discriminate between endogenous learning disabilities and language delays resulting from second language acquisition amongst ELL children who struggle academically. / School Psychology
