"We are not in position to confirm now. It will only be clear tomorrow morning when the papers will be opened," Kendriya Vidyalaya Sangathan (KYS) commissioner Santosh Singh Mall said.
All India Management Association (AIMA), which conducts the exams, was examining the content reportedly circulated on social media, and was yet to figure out from which part of the country the papers have been leaked, Mall said.
KVS is conducting exams for recruitment to various teaching posts including for Primary Teachers and PRT (Music) tomorrow.
