This year's Bailiwick average pass rate is 69.8%, which is slightly higher than the UK's 67.4%.
Almost 70% of young islanders passed their exams, receiving grades 9 to 4.
This is 2.4% higher than England, but a 6.6% dip from the year before.
(No public exams took place between 2020 and 2022 because of the Coronavirus pandemic.)
This is the first year group who did not sit the 11-plus selection process.
The President of Education, Sport & Culture Deputy Andrea Dudley-Owen says praised the cohort's perseverance.
"Completing your GCSEs, BTECs, or any other Level 2 exam is neither easy nor stress-free, so I want to congratulate everyone for their commitment and hard work in getting to this point.
For a year group whose senior education has been markedly interrupted by COVID from the get-go and with a return to the tighter 2019 grade boundaries, I hope everyone has got results they can feel proud of.
I am pleased to see the new non-selective system take shape in Guernsey and excited for the future as the system further embeds as we move ahead.”
