This information was given in Rajya Sabha by Human Resource Development Minister Kapil Sibal in response to a starred question.
Sibal said that the first phase of selection test for admission of students to Class VI in Jawahar Navodaya Vidyalayas all over the country was conducted on February 12.
He said that there were some media reports that question paper for this exam had been leaked in some centres.
"Detailed investigations made by Central Board of Secondary Education (CBSE) and Navodaya Vidyalaya Samiti (NVS) in this regard have indicated that one paper was known on 12th February 2012 only after examination was started which had no noticeable impact on the conduct of examination or the performance of candidates," Sibal said.
