The goal of this Research Brief is to identify schools in which English Language Learners (ELLs) exhibit high growth in English language acquisition. In 2015-2016, a new English Language Proficiency test, known as Assessing Comprehension and Communication in English State-toState for English Language Learners (ACCESS for ELLs) was used for the first time in Florida. In prior years, the Comprehensive English Language Learning Assessment (CELLA) was used in the State. Because these two instruments use different scales, student results are not directly comparable.
