Language proficiency

Language proficiency is the degree of skill with which a person can use a language, encompassing the ability to speak, understand, read, and write it accurately and fluently across a range of everyday and specialized contexts. Educators and linguists assess it along multiple dimensions, including grammatical accuracy, vocabulary range, fluency, and the ability to use language appropriately for different social and academic purposes, often against standardized frameworks such as the Common European Framework of Reference for Languages. The concept is central to language education, second language acquisition research, and to policy debates over how to support students who are still developing proficiency in the language of instruction.
