Headteacher Rachel Fink said: “Congratulations to all our students who will now be embarking on a wide range of higher education opportunities as well as apprenticeships and gap year programmes.
“We commend all our students who have coped superbly with the huge uncertainties as a result of COVID-19. Our staff have shown huge commitment to our students and have demonstrated that they know them well.
“Every JFS student is so much more than a national statistic and we wish each and every one of them much continued success”.
