More than 100,000 school children will today begin the 2007 Junior and Leaving Cert examinations.
Around three million exam papers have been distributed to 4,500 centres around the country for the 13-day trial which will run until June 21 for Junior Cert and June 22 for Leaving Cert students.
Examinations will be held in 89 curricular subjects and native speakers from across the EU will sit the exams in their mother tongues at Leaving Cert level.
"I want to send my best wishes to all those students sitting the Leaving and Junior Certificate examinations over the coming weeks," said Minister for Education Mary Hanafin.
"For those taking the Leaving Cert, this is an important step on their path to lifelong learning.
"All their study and hard work up until now will give them a huge choice in further studies and career options in the future."
