Just over 63% of Welsh baccalaureate students achieved the advanced diploma, compared to fewer than half last year.
Education Minister Jane Davidson congratulated students and rubbished claims that the exams were easier.
According to results on Thursday, just over 63% of Welsh baccalaureate students achieved the advanced diploma, compared to fewer than half last year.
Ms Davidson said all "can justifiably be proud" of the results and that Wales was "leading the way" with the baccalaureate exam.
Critics such as former chief inspector of schools in England Chris Woodhead, have previously argued that the exams have been "dumbed down".
Ms Davidson said: "Sadly, there are those who would wish to cast doubt on the standard of A-levels, claiming that these excellent results are due to the exams getting easier, but that is rubbish."

She said the schools inspection body Estyn had confirmed that "standards continue to improve across Wales".
That view was backed by the schools union NASUWT which warned against an "annual ritual of carping and criticism" casting "a shadow over years of work by students and teachers".
The union said any improvement in exam results should be celebrated, and not analysed to "destruction".
