A midday meal scheme was introduced in Kerala in 1984, and was gradually expanded to include more schools and grades. By 1990–91, twelve states were funding the scheme to all or most of the students in their area: Goa, Gujarat, Kerala, Madhya Pradesh, Maharashtra, Meghalaya, Mizoram, Nagaland, Sikkim, Tamil Nadu, Tripura and Uttar Pradesh. Karnataka, Orissa, and West Bengal received international aid to help with implementation of the programme, and in Andhra Pradesh and Rajasthan the programme was funded entirely using foreign aid.
