The ELPAC is the required state test for English language proficiency (ELP) that must be given to students whose primary language is a language other than English. State and federal law require that local educational agencies administer a state test of ELP to eligible students in kindergarten through grade twelve. The California Department of Education (CDE) transitioned from the California English Language Development Test (CELDT) to the ELPAC as the state ELP assessment in 2018. The ELPAC is aligned with the 2012 California English Language Development Standards. It consists of two separate ELP assessments: one for the initial identification of students as English learners (ELs), and a second for the annual summative assessment to measure a student’s progress in learning English and to identify the student's level of ELP.
