evidence: The objective of the scheme is to provide financial assistance to the Scheduled Castes and Scheduled Tribe students studying at post-matriculation or post-secondary stages to enable them to complete their education. The income ceiling of parents/guardian has recently been enhanced from Rs. 2,00,000/- p.a. to Rs. 2,50,000/- p.a. The Government of India bears the entire expenditure beyond the committed liability which is to be borne by the State Government. The committed liability of the State Government is equal to the sum total of expenditure incurred during the closing year of the last plan period. Thus, the committed liability of the State Government for the year 2012-13 shall be equal to the total expenditure incurred under each of the schemes (Post-Matric Scholarship for SC and Post-Matric Scholarship for ST) during 2011-12, the last year of the 11th Five-Year Plan period. The rates of Post-Matric Scholarship have been revised with effect from 01-07-2010. However, the Government of India has decided that such committed liability shall be decided by calculating the expenditure at the pre-revised rates. The State Government follows the rates fixed by the Government of India. However, in cases of Post-Matric Scholarship for hostellers in Group III & IV are less (Rs. 570/- & Rs.380/- per month respectively) than the rates fixed by the State Government, the State Government pays at higher rates fixed by the State Government (Rs.750/- per month) and the additional burden is borne by the State Government.
