Around 50,000 students received their Junior Cert results today amid concerns over high failure rates in some subjects.
Failure rates in ordinary-level French and various technical subjects remain high.
Some 14 per cent of students failed ordinary-level French. A similar percentage failed the exam last year. The failure rate at higher-level French increased to 7 per cent this year.
In a positive signal, 87 per cent of students opted to take the revised science curriculum, which is less bookish and more practical in its approach.
In all, some 78 per cent of students secured an honour (grade C or better) in higher-level science, slightly down on last year. The honours rate in maths at higher level (77 per cent) was also slightly down on last year. Approximately 7 per cent of students failed ordinary-level maths.
In a repeat of the pattern at Leaving Cert, fewer students are taking maths at higher level in the Junior Cert; the number taking higher level was down by 2 per cent this year.
Ibec, the group that represents Irish business, called for the re-evaluation of the Junior Cert curriculum.
President Mary McAleese today sent her congratulations to students and urged them to celebrate sensibly.
"Today represents a significant milestone in your formal education and I hope it will encourage you to keep striving to develop your fullest potential," she said.
"Ireland is fortunate to have so many responsible and civic-minded young people and as you celebrate your achievements today please make us even more proud of you still, by celebrating sensibly with care for yourselves and care for others."
The Dublin Rape Crisis Centre warned students celebrating results to take steps to remain safe. They should stay with their friends, ensure their drink is safe and not accept a drink from a stranger. They should also share taxis, ensure their mobile phone is fully charged and always let someone know their plans if they are travelling alone.
