Honley High School has posted results slightly down on last year - but still way above the national average.
Last year the school had its best-ever GCSE results with a 78% pass rate for five grades A* to C including English and maths.
This year the rate was 73%, compared with a national figure of just under 60%.

Headteacher Paul Greenhough expected the dip, believing it to be in line with tougher exam marking.
He said: “We are a little down on last year, but this is reflective of the change in exam assessments nationally, which we have seen feed through into results.
“We have had some very good results in English and maths. We are in a situation where we are getting students on to the next level, and that is my main concern.
“Putting a significant number of English students in for early entry last November has paid dividends, and out maths results are very, very strong.
“There is going to be some work to do over the next 12 months and we have a solid base to make the next leap forward.”
