THE Corrupt Practices Investigation Bureau (CPIB) is investigating what is believed to be the first case of cheating in the Primary School Leaving Examination (PSLE).

The New Paper reported yesterday that a teacher in a school in the north had allegedly corrected the wrong answers in the scripts of three pupils after the Tamil language PSLE paper was conducted early last month.

The pupils' original answers were crossed out and rewritten in a different ink and handwriting.

The changes were discovered at the marking stage. They were believed to have been done during the short period when invigilators collected the scripts, tied them up and submitted them to the chief invigilator at the end of the exam.

When contacted yesterday, a CPIB spokesman said a teacher is under investigation.

Markers of the papers at Farrer Park Primary had discovered that the answers of a pupil's composition paper, or Paper 1, had been changed. When they checked the same pupil's Paper 2, they found that some of the answers there had also been tampered with.

A full check was conducted, with similar changes found in the Paper 2 scripts of two other pupils.

By then, the Paper 2 scripts had already been marked, with marks given to the altered answers.

When contacted, the Singapore Examinations and Assessment Board (SEAB) said the affected scripts have since been re-marked by its chief examiner for Tamil language, based on the original answers.
