Few classroom measures of English language proficiency have been evaluated for reliability and validity. Researchers have examined the concurrent and predictive validity of an oral language test, titled A Developmental English Language Proficiency Test (ADEPT), and the relationship to the California English Language Development Test (CELDT) in the receptive/listening and expressive/speaking domains. Four years of retroactive data representing 392 student records were obtained from a local urban school district in Los Angeles County with a significant proportion of English language learners. After preparing the data file for analysis, data was analyzed using the Statistical Package for the Social Sciences (SPSS) system. Cronbach’s alpha was used to analyze the internal consistency of ADEPT. Pearson r analysis was performed to examine concurrent validity and predictive validity. Findings indicated moderate to high correlation coefficients of internal consistency in the first three levels of ADEPT. Concurrent validity results varied depending on the school year. In the most recent school year, 2012–2013, positive moderate to strong correlations were found. This relationship was weaker in each previous year. Overall, correlations increased and remained positive as sample size increased but predictive validity was weak for all three sets of comparative years. These findings support the use of ADEPT as a multiple measure, as a monitoring tool and to inform instruction.

As the population of English Language Learners (ELLs) continues to grow in schools, so does the concern for their lack of academic progress and the possible inequitable representation of this culturally and linguistically diverse population in special education (Artiles, Rueda, Salazar, & Higareda, 2005; Guiberson, 2009; Mac Swan & Rolstad, 2006; Rinaldi & Samson, 2008). Of particular concern is the increase of ELLs with an eligibility of Specific Learning Disability (SLD), especially when examined at the local level (Klinger, Artiles, & Barletta, 2006). To understand this phenomenon at the local level, this mixed-method study examined ELLs with SLD in a large California urban school district by targeting English language development (ELD) at the macro and micro level. The researcher accomplished this focus by examining the relationship between English language proficiency levels, grade levels, and type of learning disorder among kindergarten through twelfth grade ELLs with SLD. The researcher analyzed cumulative educational records of three eighth grade ELLs with SLD, including Individualized Educational Programs (IEPs), to examine how ELD needs have been addressed. The results of the quantitative portion of this study revealed greater distribution patterns of ELLs with SLD in sixth through ninth grades. The researcher also found ELLs with SLD to be primarily represented in the early stages of ELD (beginning, early intermediate, and intermediate) and identified with an auditory processing disorder. Results of the case studies also revealed that after nine years of ELD instruction, the students had not reclassified as English proficient and documented evidence of ELD instruction and support was minimal.
