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 schools administer a state test of ELP to eligible students in Extended Transitional kindergarten (ETK) through grade twelve. 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.
