Students in kindergarten through grade twelve whose home language is not English are required by law to be assessed in English language proficiency (ELP). In California, the ELP assessment is the CELDT.
The CELDT allows schools to identify students who need to improve their skills in listening, speaking, reading, and writing in English. Schools also give the test each year to students who are still learning English.
State and federal law require that local educational agencies administer a state test of English language proficiency (ELP) to eligible students in kindergarten through grade twelve. The California Department of Education (CDE) is transitioning from the CELDT to the ELPAC as the state ELP assessment by 2018. The ELPAC will be aligned with the 2012 California English Language Development Standards. It will be comprised 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.
