Previous research has linked language issues to transfer of cultural identity from one generation to another, access to better employment and access to judicial and administrative systems. Language policy measurement, then, should be conducted from the angles which best fit those particular functions of language.
Education and administration are the most often mentioned. Both Edwards (1985, 118–19) and Fishman (1997) observe that although education in a mother tongue does not necessarily contribute to the preservation of that particular language and may in fact contribute rather to the process of linguistic assimilation, education is often perceived as a central factor in maintaining group identity and therefore has a strong symbolic role for linguistic minorities. Bretton (1976, 445) and Chaklader (1990, 94) link choice of language for education to choice of language for courts. Varennes (1998, 158) perceives “great potential for destabilisation” in the denial of native-language education. Some language policies cover broadcast and publishing media. Others include special language requirements for government employment or certain professions.
