Justice Ronnie Boodoosingh said it is time the mystery of how students are placed in Secondary Schools be brought to light.
The parents of the girl had challenged their daughter's score, and had requested to see her scripts under the Freedom of Information Act.
The child, despite scoring marks in the 90s in various class tests, had obtained marks in the 80s, and failed to get her first choice Secondary School.
She had attended a Primary School in Orange Grove, Tacarigua.
Justice Boodoosingh said the Ministry seemed to be taking the approach of "washing its hands of the issue."
He said no argument had been put forward to indicate there was any harm to either the State or private interest in the child, or her parents viewing the papers she had written.
