About Centrally Sponsored Schemes:
Definition: 
CSSs are Schemes that are funded jointly by centre and state and implemented through the State in sectors falling in the State and Concurrent Lists of the Constitution.
Key Points:
📍These are schemes that are funded partially by both the Central and State Governments.
📍It is a channel which the central government uses to help the states run their plans financially.
📍The amount of state participation varies from state to state.
📍Their implementation rests on the Union territories and the States.
📍These schemes are further divided into three categories based on their funding patterns i.e. the core of the core, core and optional.
📍The flagship schemes of the central government are called Core of Core schemes or umbrella schemes.
Examples: Mahatma Gandhi National Rural Employment Guarantee Programme (MGNREGA), National Social Assistance Programme etc.
📍Core schemes: The funding pattern is usually 60:40. The central government takes up more share in these schemes and the states are expected to pitch in the remaining funds.
📍Although, in cases of difficulty where states like North Eastern states, Jammu & Kashmir, and some special category states need extra attention, a 90:10 ratio of funding can be seen usually.
Examples: Pradhan Mantri Gram Sadak Yojana (PMGSY), Pradhan Mantri A was Yojana (PMAY), Integrated Watershed Development Programme etc.
📍Optional schemes: Normally state governments plan the schemes and request the central government to fund some portion of the total outlay. The general funding pattern of the optional schemes is 50:50 (State: Center).
However, the Central government may take up the task of funding more if the scheme is to be implemented in backward areas or difficult terrains.
Examples: Border Area Development Programme, and Shyama Prasad Mukherjee Rurban Mission among others.
