From the stress of results day to the buzz surrounding the school formal, they show life as pupils experienced it two decades ago.
The pupils pictured will be in their 30s now, perhaps with children of their own.
But, if that’s you, this trip down memory lane will make you feel once again like a spotty teen whose biggest worries were getting your homework done and plucking up the courage to talk to your school crush.
This retro photo gallery features pupils and teachers at schools around Northern Ireland during the mid-noughties.
Star pupils who excelled in the fields of academia and sport, kind-hearted youngsters doing their bit for charity, and BFFs unwinding outside the classroom are all pictured in these evocative images.
There’s even an ex-pupil among them who was picked to appear alongside Johnny Depp in a Hollywood film.
Can you spot yourself or an old school friend in these photos? For more Northern Ireland nostalgia, check out this look back at noughties days out.
