The BLP is meant to assess healthy bilinguals from a variety of linguistic and cultural backgrounds. It can be used in such bilingual contexts as second language acquisition, heritage learning, attrition, in situ or immigrant contexts, sequential or simultaneous bilingualism. Due to the introspective nature of the questions, it should be administered to bilinguals who are at least of high school age.
The BLP is open and free for anyone to use. The work is licensed under a Creative Commons Attribution-NonCommercial-ShareAlike License.
