The full information which the Deputy has requested is not available. However, chapter 9 of "PISA 2009: Results for Ireland and Changes Since 2000" which was published by the Education Research Centre in June 2012 outlines student performance on the various item types. This is available at:http://www.erc.ie/documents/pisa2009main_nationalreport.pdf. In addition, the Education Research Centre has analysed performance in PISA 2003 and 2009, and compared the percent correct, incorrect, missing and not reached on all items, and multiple choice, short response, and longer written response items for a set of mathematics items that was administered in both cycles. This information on the performance of Irish students is available at the link: http://www.erc.ie/documents/engagement_and_performance_over_time.pdf.
