Primary Education It is rather difficult to say when and where the institutional form of primary education was introduced in the geographical region of Bangladesh as a part of the Greater India. The origin of institutionalised education can be traced back to the time of the composition of 'Rg Veda', almost 3000 years ago in this subcontinent. The Dravids, Huns, Aryans and Mongols. Later the Arabs, Turks, Afghans, Portuguese also established their habitats here. There was no clear distinction between the primary and secondary level of education in the initial stages of formal/institutional education. So, it is very difficult to describe the primary education of that time separately.
