Cognitive Academic Language Proficiency
(CALP) is a language-related term which refers to formal academic
learning, as opposed to BICS
. In schools today, the terms BICS and CALP are most frequently used to discuss the language proficiency
levels of students who are in the process of acquiring a new language. These students typically develop proficiency in BICS well before they acquire a strong grasp of CALP or academic language. As a result, students may initially appear fully proficient and fluent, while still struggling with significant language gaps.
