Explanation:

After India obtained independence, a critical mass of Bodo intellectuals realized the need for preservation of Bodo language. Many early Bodo authors studied in schools and colleges, where medium of instruction was either Assamese or Bengali. Bodo intellectuals felt that Bodo language must be preserved and developed at par with Assamese and Bengali languages. Bodo people realized very late that the education was the key component to the overall development of Bodo people and their language. After prolonged struggle and determination of the Bodo Sahitya Sabha (Bodo Literary Organization), the Bodo language was introduced as a medium of instruction at primary level in 1963 and then at secondary level in 1968. Bodo language and literature has been recognized as one of the Major Indian Languages (MIL) in Gauhati, Dibrugarh and North-Eastern Hill Universities. In 1985, Bodo has been recognized as an associated state official language of Assam.
