This document discusses language-in-education policies in Southeast Asia. It notes that many ethnic minority groups face barriers to education due to differences between the language used at home and the language of instruction in schools. While national languages are primarily used for instruction, some countries are piloting multilingual education programs that incorporate local languages. However, monolingual policies also persist due to beliefs that using multiple languages will confuse students or hinder learning of dominant languages. Overall, the document examines the complex issues around language policies in education across Southeast Asian countries.
