The Miao Script (formerly the Pollard Script) has been adapted to nine languages in three different language groups: Hmongic, Lolo-Burmese, and Burmic. It has been standardized by the International Standardization Organization. Historically, it was used for official publications in China and for literature and literacy development within the nine ethnolinguistic groups. Five of them still use the script. In the past decade, more than twenty languages in these three groups have been newly recognized, which raises the question of its potential for use in literacy development among the least literate of these groups.
