The ceilidh on June 28, featuring music from the Steven Carcary Band, will be hosted at the Laurencekirk secondary school, which is to close at the end of next month.
Pupils will move to the new Mearns Academy Community Campus nearing completion in the town after their summer holiday.
Mearns Academy will also be hosting an open day on June 14, at which there will be a coffee morning with stalls and raffle.
There will also be an opportunity to listen to the school orchestra and a final tour round the building for those not going to the ceilidh.
Former pupil Audrey McPherson, a member of MAGC who are organising the ceilidh, is also working behind the scenes for the open day.
She said: ‘‘The response to the request for photographs has been fantastic.
‘‘We would like to thank all those that have brought their images in to the community centre.
‘‘However, we are still looking for some more.
‘‘If you think you may have some lurking away deep in a cupboard somewhere, we would very much appreciate it if you could bring them in.
‘‘We would also like to thank the staff at the community centre for taking in the photos and for selling the ceilidh tickets for us.
‘‘The ceilidh will be on from 7.30 - 11pm and there will be stovies and a licensed bar.
‘‘It’s going to be a fantastic night.’’
Audrey, who attended the Academy in the 1980s, added: ‘‘There will be a bouncy castle and face painting for our younger visitors.
‘‘It promises to be a nostalgic but fun day for those visiting.’’
