Protocol - English Proficiency
The respondent completes a question from the California Health Interview Survey (CHIS) asking for the respondent’s own opinion of how well he or she speaks English.
The Working Group recommends that the interviewer ascertain what language is spoken in the home, such as “Does this person speak a language other than English at home?” and “What is this language?”. This protocol is only asked of a participant who speaks a language other than English at home. For languages other than English, this protocol may need to be asked by a translator. See http://healthpolicy.ucla.edu/chis/design/Pages/Questionnaires%20(Translated).aspx for translated protocols in languages other than English.
Since you speak a language other than English at home, we are interested in your own opinion of how well you speak English. Would you say you speak English…

English proficiency is an individual-level measurement of spoken English language proficiency.
Limited English proficiency (LEP) status is associated with multiple health care disparities and places patients at risk for decreased quality of care and in disaster/safety events. It is associated with lower educational attainment and limited employment opportunities. These questions help understand how well an individual speaks English and analyze and plan programs for adults and children with limited proficiency.
