The director of the Joint Council for Qualifications said "underlying factors" affected the dip in GCSE results but praised the "upturn" in the number studying modern languages.
There are many underlying factors affecting this year's GCSEs, including a sizeable increase in entry by 15-year-olds, new science specifications designed with greater challenge, early and multiple entry in mathematics and an increase in the number of students taking IGCSEs.
All of these have had an impact on entries and results.
This year's upturn in languages will be welcomed across the education sector and beyond. Not since 2008 have there been this many entries in languages.
However, it remains to be seen if this is the start of a trend and if more students decide to continue to study a language at A-level.
Pupils around the country received their long-awaited GCSE results today - here are some of the stories behind the results.
The proportion of GCSEs awarded at least a C grade this summer fell 1.3%, marking the biggest fall in the exam's 25-year history.
On the day that 650,000 students get their GCSE results, the Tonight programme asks whether the exams are fit for purpose.
