The English Language Proficiency Assessments for California (ELPAC) will be succeed the California English Language Development Test (CELDT). The CELDT is the current 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 (or year one of a two-year kindergarten program, sometimes referred to as "transitional kindergarten") through grade twelve. The California Department of Education (CDE) aims to transition 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, and will be comprised of two separate ELP assessments:

  • An initial identification of students as English learners
  • An annual summative assessment to measure a student’s progress in learning English and to identify the student's ELP level

    CELDT Analysis

    Districts can obtain the results of the annual administration of the CELDT from Educational Data Systems in late December/early January. (CDs with student data are no longer sent to districts, except by special request.)

    To help schools use their electronic CELDT data, SCOE offers free workshops and consultation services. These services include conversion of the CELDT data file to a more user-friendly Microsoft Excel format and training to enable districts to use Microsoft Excel as a tool to analyze, sort, and filter the data so that it helps reveal student needs.

    For assistance converting district data to Microsoft Excel, contact Rick Phelan, or 524-2847. Note that data conversion must be requested at the district level, not by individual schools or classrooms.
