Six Point Formula is the solution proposed by Smt. Indira Gandhi in 1973, in order to end the separatist movement in the Kosta-Seema regions in opposition to the mulki rules. Smt. Gandhi's solution was accepted by the leaders of all regions. As per this solution, the state was divided into 6 zones. Zone-I has Srikakulam, Vizianagaram, and Visakhapatnam districts. Zone-II has East Godavari, West Godavari, and Krishna districts. Zone-III has Guntur, Prakasam, and Nellore districts. Zone-IV has Chittoor, Cuddapah, Ananthapur, and Kurnool districts. Zone-V has Adilabad, Karimnagar, Warangal, and Khammam districts. Zone-VI has Hyderabad, Rangareddy, Nizamabad, Mahboobnagar, Medak, and Nalgonda districts.
In each zone 70% of non-gazetted, and 60% of gazetted posts were reserved for locals. In addition, 80% of class-IV posts were reserved to locals of the district. Certain exceptions were made to Hyderabad city for state level organizations allowing people from all regions to work in these offices.
Government Order 610 was issued in 1985 by the TDP government of Sri N.T. Ramarao, to correct the irregularities that have occurred in the implementation of the Six Point Formula.
