This interpretation guide provides information about the CELApro administered in 2010. CELApro is the language proficiency assessment used as one data point in the body of evidence for classifying and monitoring the progress of English Learners (ELs) in the acquisition of English. This assessment measures social and academic language use in four major skill areas-Listening, Speaking, Reading, and Writing-along a continuum of five language development levels: Beginning, Early Intermediate, Intermediate, Proficient, and Advanced. The assessment takes into account the students' maturation and cognitive skills by providing age-appropriate tests covering the following grade spans: K, 1, 2, 3-5, 6-8, and 9-12.
