The number of girls who sat Computing GCSEs in England, Wales and Northern Ireland more than doubled this year from 5,700 in 2015 to 12,500 in 2016.
The increase partially reflects an overall rise in the number of students taking Computing GCSEs, which was up by 76 per cent from 36,000 in 2015 to 62,000 in 2016.
In contrast, the number of ICT GCSEs, which are focused more on skills in the day-to-day use of technology, dropped by 25 per cent between 2015 and 2016 to 84,000.
This follows changes in policy in 2012 and 2013 by former education secretary Michael Gove to toughen up the ICT curriculum while adding Computing GCSE to next year's English Baccalaureate.
The new curricula were introduced in September 2014 and this year's entrants were the first to be tested under the more rigorous regime.
The increase in Computing GCSEs sat by girls this year brings the proportion up from 16 per cent in 2015 to 20 per cent today, compared with 41 per cent for the ICT GCSE.
Girls who take these subjects perform disproportionately well. Around 24 per cent of the girls who sat Computing exams achieved A or A*, compared with 20 per cent of boys. Meanwhile, 26 per cent of the girls who sat ICT exams achieved an A or A*, compared with 17 per cent of boys.
However, overall achievements for Computing were relatively weak. Just 60 per cent of Computing GCSEs taken resulted in A*-C grades in Computing, compared with 68 per cent of ICT GCSEs and 67 per cent for all GCSEs.
The figures come amid a UK-wide digital skills shortage. Over half of technology businesses recruiting digital specialists have reported difficulty filling vacancies.
"It is encouraging to see such a growth in the uptake of Computing GCSE, and some real progress in the proportion of girls," said Karen Price, CEO of the Tech Partnership.
"Demand for digital specialists continues to grow, and employers need 138,000 new people a year to enter the workforce in such roles.
"We must do even more to make the curriculum in schools attractive to both girls and boys, and inspire them about the huge variety of digital careers available."
Price added that many employers work through the Tech Partnership on a range of initiatives to encourage more girls to study computing at GCSE, as well as helping overcome the skills deficit in the IT industry.
These include providing new ways for young people to acquire and demonstrate skills that are valued by industry, employer-backed Tech Industry Gold degree apprenticeships, and TechFuture Badges through which students can use a flexible range of resources to acquire online 'badges' certifying acquired IT skills.
