6.2 Language Systems, BICS, and CALP

6.2 Language Systems, BICS, and CALP

Quick answer: PECT objective 0003.2 asks for language systems, structures, functions, and variation, the difference between academic language and social language, and similarities and differences between first- and second-language acquisition and literacy. The exam-usable core is Cummins's BICS vs. CALP: a child can sound fluent at recess and still lack the language to explain a science investigation. A silent period can be typical. L1 transfers into L2. Do not treat a commonly cited '5–7 years for CALP' figure as a Pennsylvania cut score.

If 0003.1 was culture, this descriptor is language as a system. You do not need a linguistics degree. You need to hear which layer of language is in play when an English learner stumbles, and you need to stop calling playground talk 'proficiency done.'

Language systems, structures, functions, and variation

Five systems show up in PreK–4 rooms. A difficulty in one is not automatically a disability.

Functions are jobs language does: greet, request, retell, compare, justify, hypothesize. Social functions (asking for a crayon) are not the same as academic functions (explaining why ice melted). Variation includes dialects and registers. A variety of English (including African American English or a regional Pennsylvania variety) is a rule-governed system, not 'broken English.' An English learner may also be learning a new register (playground vs. science talk). Do not collapse dialect, register, and disorder into one 'incorrect' pile.

Code-switching (moving between languages or varieties in one conversation) is typical bilingual behavior and can support meaning. It is not proof the child is confused.

Social language vs. academic language: BICS and CALP

Jim Cummins distinguished:

• BICS — Basic Interpersonal Communicative Skills: contextualized, face-to-face, social language (recess, lunch, 'Can I play?'). Gestures, shared objects, and here-and-now context carry a lot of the meaning.
• CALP — Cognitive Academic Language Proficiency: decontextualized language used to learn content (explain, compare, infer, read informational text, write a constructed response). Fewer gestures; more precise vocabulary and complex syntax.

Exam-usable rule: Conversational English can look 'fluent' while academic language lags. A Grade 2 child who jokes in English on the playground and then cannot explain a STEELS investigation is not necessarily lazy and is not automatically language-impaired. The child may have BICS without CALP for that content.

Teacher-prep texts often cite about 1–3 years for BICS and about 5–7 years (sometimes longer) for CALP, depending on age of arrival, L1 literacy, prior schooling, and quality of instruction. Treat those numbers as a commonly cited range, not a law, not a PECT passing score, and not a Pennsylvania reclassification deadline. PDE reclassification uses state procedures and ACCESS for ELLs® results — not a Cummins calendar. If an option says 'CALP is legally finished in five years' or 'the PECT requires seven years,' reject it.

Cummins also described a common underlying proficiency (CUP): conceptual knowledge and literacy processes in L1 support L2. The iceberg image is useful: two language peaks above the water, one shared cognitive base below. A child who already reads in Spanish is not a non-reader; print concepts, phonological insight, and world knowledge can transfer. Forbidding L1 to 'speed English' can undercut that base (subtractive bilingualism). Supporting L1 while adding English is additive.

Similarities and differences: L1 vs. L2 acquisition and literacy

Similarities

• Children need meaningful, comprehensible input, not only isolated drills.
• Development is sequential and errorful. Errors can show progress (overregularizing goed is a morphology milestone, not random failure).
• A silent period can occur: the child listens, watches, and may respond with gestures before producing much speech. More common in young L2 learners. It is not by itself a language disorder.
• Play, interaction, and responsive adults grow language in both L1 and L2.

Differences

• L2 learners are usually older than infants acquiring L1. They bring world knowledge, school experience (sometimes interrupted), and an existing language.
• Transfer from L1 can be positive (cognates such as animal/animal, shared print concepts) or can produce interference (phonology or word order that follows L1). Transfer is information, not proof of disability.
• Affective factors (anxiety, identity, family separation, how the school treats the home language) matter more visibly in L2.
• Time pressure is different: a four-year-old acquiring L1 is not also expected to pass a Grade 4 constructed response next month. ELLs are doing two jobs — content and English.
• Literacy: If L1 literacy exists, map English onto what the child already knows about print. If L1 is oral-only so far, build oral language and print together, still using L1 meaning. Invented spelling in English can be typical L2 literacy, just as in L1 (0001.2), especially when the child is mapping new phonology onto English letters.

Interlanguage is the learner's systematic in-between grammar. It changes with input and instruction. Do not treat every interlanguage form as a speech-language referral.

Classroom snapshots the exam likes

Playground fluent, science stuck. Do not say 'he's fine in English' and move on. Teach the language of the investigation (compare, because, evidence) with frames and visuals (6.3).

Newly arrived and quiet. Provide input she can understand, yes/no and pointing responses, a peer buddy, and time. Forcing a public sentence on day three raises the affective filter. Persistent silence in L1 as well, across settings, with no gesture or play, is a different pattern — that belongs in 6.4.

Reads well in Arabic, struggles with English decoding. That is an L2 mapping problem plus new orthography, not automatic SLD. Use L1 literacy as a bridge.

Mixes languages in a retell. Typical. Probe meaning. Teach the academic English form after you understand the idea.

Exam traps for 0003.2

• Equating BICS with 'done learning English.'
• Treating a silent period as refusal or as an automatic disability.
• Calling L1 use, code-switching, or accent a disorder.
• Claiming a universal 5–7-year CALP cut score.
• Assuming L2 never resembles L1 development, or assuming they are identical so transfer cannot help.
• Confusing this descriptor with ELPS documents (6.3) or with IEP law (Chapter 7).

When a stem shows a child who 'speaks English fine' but cannot do the academic talk, name CALP. When a stem shows a quiet newcomer who follows routines, name a possible silent period. When a stem shows strong L1 literacy, name transfer and CUP.
