The warning comes following several complaints received by the Central Board of Secondary Education (CBSE) about withholding of admit cards by certain schools and in some cases charging of fee for their release.
"Several instances of not issuing admit cards by various CBSE affiliated schools on grounds of performance of students in pre-board tests (conducted by schools internally) have come to the notice of the board. It has also been noted that some schools are charging fees for release of the admit card," CBSE controller of examination KK Chaudhary said in an advisory to schools.
The advisory also stated that the board issues admit cards to only those students which have been sponsored by the schools in their final list of candidates submitted to it.
"Therefore, their eligibility for the exams has already been confirmed by the school and hence their admit cards cannot be withheld. The schools also cannot charge any fee for issuing admit cards," it said.
