Assessment and Instruction
What you must know
California identifies English learners through a home language survey followed by an initial English proficiency assessment; annual summative measurement is the ELPAC, which reports listening, speaking, reading, and writing plus an overall level. Reclassification is a multi-criteria decision: ELPAC performance, grade-level academic benchmarks in English language arts, teacher evaluation, and parent/guardian consultation. No single score reclassifies a student.
Instructionally, sheltered instruction (SDAIE) makes grade-level content comprehensible through visuals, realia, modeling, cooperative grouping, sentence frames, and both a content objective and an explicit language objective. Specially designed academic instruction must teach the language of the discipline, not just the facts. Assessment vocabulary matters: formative (in-the-midst, guides teaching) versus summative (end-point, judges learning); accommodations change access without changing what is measured (extra time, bilingual glossary, directions read aloud); modifications change the construct or expectation (fewer items, simplified text on a reading test). Always ask: what is this instrument supposed to measure?
Traps
- Confusing accommodations with modifications - a glossary is access; a shortened reading passage changes the construct.
- Assuming low English scores mean a learning disability. Rule out language acquisition and instructional history first, and gather data in the primary language.
- Believing a student must be fully fluent before receiving grade-level content - content and language are taught together.
- Overlooking test bias: items relying on culturally specific background knowledge threaten validity.
Worked example
A seventh grader scores below basic on an English reading test. Do not conclude "reading disability." First check: was the test administered with allowable accommodations? Was the student's schooling history interrupted? Does a primary-language assessment show similar difficulty? Do formative running records show growth? Only converging evidence - similar struggle in L1, flat progress despite strong sheltered instruction - supports referral. Otherwise, the finding is a language-development artifact and the response is instructional.
Rule of thumb
Match the tool to the purpose: screening, placement, progress monitoring, and summative judgment are different jobs and are not interchangeable.
