Representing over 50 schools from Milton Keynes, Bedfordshire, Buckinghamshire, Hertfordshire, Oxfordshire, East Anglia and London, the students have been manufacturing and selling a variety of products and services during their academic year in the Young Enterprise company programme and team programme.
They have learned about business first hand through setting up and running a real company.
With advice from local business volunteers, the students elect a board of directors from among their peers, raise share capital and market and finance a product or service of their own choice.
At the end of the year they liquidate the company and present a report and accounts.
Some of the products on sale at the Young Enterprise Milton Keynes Trade Fair will include bags, apps, music CDs, personalised T-shirts, books, toys, wooden items, cards, mugs, key rings, magnets, mirrors and juggling balls.
Phil Simons, Young Enterprise manager for Milton Keynes, said: "This is the 12th major YE fair at thecentre:mk. It will be a marvellous showcase for the achievements of these young budding entrepreneurs in developing their skills, knowledge and confidence, in just one year.
“We are extremely grateful to threcentre:mk for their continued support of this event."
