Which assessment measures English skill levels in reading, writing, listening, and speaking?

The Arizona English Language Learners Assessment (AZELLA) is specifically designed to evaluate English language proficiency in key areas such as reading, writing, listening, and speaking. This assessment is utilized within Arizona to determine the levels of English language proficiency among students, particularly those who are English Language Learners (ELLs).

AZELLA serves multiple purposes, including placement in appropriate English language development classes and measuring progress in English language acquisition over time. Its comprehensive nature ensures that it effectively assesses all four primary communication skills, making it a critical tool for educators in supporting ELL students.

Other assessments might focus on specific aspects of language or serve different purposes, but AZELLA is uniquely tailored to provide an overall measure of English proficiency across the four essential skills, which is why it is the correct choice for this question.
