The Arizona English-Language Learner Assessment (AZELLA) is the backbone of Arizona’s new English-Language Learner (ELL) policy in that it is used to assess students’ English-language proficiency in order to place them into groups for English-language instruction and to determine when English learners have become proficient in English. 


AZELLA is a standards-based assessment that meets both state and federal requirements to measure students’ English language proficiency. AZELLA is used for both placement and reassessment purposes. Students who have been identified as second language learners on the Home Language Survey take the AZELLA placement test, and the students’ proficiency scores determine appropriate placement for instruction. Students who have been placed into an English language learner program will also take the AZELLA reassessment once a year until they achieve proficiency. Students who have scored proficient on the AZELLA are then monitored for two years to help ensure student success after they are exited from the English language program.
