July 27, Colombo: Sri Lanka's Irrigation and Water Resources Management Minister Nimal Siripala de Silva says a detailed report on the Z-scores of last year's GCE Advanced Level examination would be completed in two weeks.

He has said the report would be a comprehensive one explaining the irregularities in the old and new Z-scores.

He has explained that the President had directed Higher Education Minister S.B. Dissanayake to prepare a report including the statistics of students who took the national examination under the new and old syllabuses last year.

The Minister has added that it was the government's duty to ensure that students do not suffer any injustice and that steps would be taken to address their issues.

The Minister told the other political parties that there was no reason for them to try and capitalize on the Z-score issue and protest since the scores were not calculated by either the President or the Minister.

"The Z-scores were calculated by mathematicians, professionals and intellectuals. There was no political interference," he has said.

Following last month's Supreme Court ruling to annul the Z-scores of the national examination results, Sri Lanka's main opposition United National Party has called on the Minister of Higher Education to step-down.

The Supreme Court ordered the University Grants Commission (UGC) to annul the previous Z-scores and re-calculate the score according to old and new syllabuses separately and re-issue.

The Z-score formula which is used to select the entrants to the universities had been jointly prepared by the University Grants Commission and the Ministry of Higher Education.
