The Bilingual Articulation and Phonology Assessment (BAPA) was developed for the purpose of assessing the articulatory and phonological abilities of monolingual and bilingual speakers of English and Spanish. BAPA can also be used to assess articulation and phonology skills of either monolingual English speaker or monolingual Spanish spakers. Best practices for assessment of speech sound disorders for bilingual children recommends an assessment of all languages spoken by the child. Through assessing both languages, one can more easily rule out or explain second-language influences and can describe errors observed in both languages as well as those errors specific to each language. This evaluation is to be considered as part of a full speech evaluation to include: measures of intelligibility, considerations for second language influence, and considerations for the age of acquisition of each phoneme. The BAPA was developed by Barbara Fernandes, Ellen Kester, Mary Bauman, and Scott Prath, and published by Smarty Ears. The BAPA can be used with individuals of all age groups. The BAPA is compatible with the iPad running iOS 6.0 or above.
