Wakatipu High School's NCEA results show pupils achieved higher results last year than the year before.
Last year's results, released by the Qualifications Authority, show the school had higher excellence, merit and pass rates in all of the three levels than it did in 2008.
In 2008, no pupils achieved excellence at Level 2 and 3, but this year 11.6% of those sitting NCEA Level 2 achieved excellence and 1.9% of those at Level 3.
However, most of the excellence, merit and pass rates were still below the national average for each level.
Excellence and merit Level 2 rates were above the national average as were merit rates in Level 3.
All the other rates were trailing the national average.
Principal Lyn Cooper said she was thrilled with the results.
"It was one of our goals last year to raise the number of students receiving certificates endorsed with merit and excellence," she said.
The school had revamped the classing system so year 8, 9 and 10 pupils aged between 12-15 years are put in classes according to learning ability rather than age.
Year 12 pupil Bruno Shirley achieved an outstanding scholarship in history.
