This year's Leaving Certificate students could find out over the weekend or by Monday whether their results will be improved on foot of corrections to errors in the calculated grades process.

Minister for Education Norma Foley told the Dáil last night that an independent review of all grades awarded may be completed as early as today.

The review is to determine how many students are to have the grades they received raised as a result of correction.

Ms Foley said once her department receives the outcome of the review, she will make the information available to students "at the earliest opportunity".

This review will produce the final figures, the minister added.

Later, a spokesperson for Ms Foley told RTÉ News that once it is done the Calculated Grades Executive Office will "finalise results", this could take "a day or two" and students will then be notified.

The corrected results will also be forwarded to the CAO (Central Applications Office) which will take about one week to be able to determine which students are entitled to renewed college offers and to make those offers, some of which are likely to be on a deferred basis.

The minister also announced an extension to the deadline from today until next Wednesday to register to sit the postponed exams in November.

In the Dáil, Ms Foley defended what she said were layers of oversight in the calculated grades process.

While Canadian company Polymetrika developed and ran the statistical model for the department, the Irish Education Research Centre provided quality assurance and verification.

It was running the data in parallel with the contractor, the minister said.

Ms Foley said Polymetrika was an expert in the highly specialised field of statistics and psychometrics and had been engaged by the Department of Education to work on contingency plans prior to the announcement of the calculated grades process in early May.

Announcing details of the mistakes on Wednesday the minister said they had been made by Polymetrika.

In the Dáil last night, she said that in any contract there were penalties and that the matter "will be pursued".
