The move, aimed at improving efficiency and transparency, comes following a push from the Central government to link the Aadhaar number with subsidy schemes related to school education.
The Department of School Education and Literacy (DSEL), under the Human Resource Development ministry, has decided to give a window till June 30 to those who do not have an Aadhaar card yet.
"The use of Aadhaar as identity document for delivery of services, benefits or subsidies simplifies the government delivery process and enables beneficiaries to get their entitlements directly and in a seamless manner," a senior ministry official said.
"A notification will be sent to schools that students desirous of availing the benefits under the Mid-day meal scheme will be required to furnish proof of possession of Aadhaar number or undergo the authentication," he added.
"The cook-cum-helpers are also treated as beneficiaries under the scheme and hence they will also be required to furnish Aadhaar numbers," the official said.
In an inter-ministerial meeting earlier this year, DSEL had raised concerns over the decision to use the Aadhaar number as an identification document for receiving benefits under various school-related schemes saying the plan needs more deliberation.
