The link for the document - Calculated Grades for Leaving Certificate 2020, Guide for Schools on Providing Estimated Marks and Class Rank Orderings is posted below. I will review document and have a zoom meeting early next week to explain further information contained in the document. It will be emailed to all students also.
Kind Regards,
John Keane
