Each one of the apprentices and trainees has a disability and the qualifications were gained through a specially created scheme run by Unity Kitchen, the social enterprise arm of disability charity the Camden Society.
Tanni Grey-Thompson said: "It is an honour for me to be presenting the certificates to the apprentices and trainees. It is important to celebrate their achievements and they can be proud to know that they have met the high demands of the scheme and have come through it with flying colours.
“Unity Kitchen is a pioneering scheme in the way that it allows those with learning disabilities to get into the industry.
"Having the Unity Kitchen Cafe at the Queen Elizabeth Olympic Park is another way of fulfilling the legacy of the 2012 Olympics and Paralympics and it is has proved to be a great place for the graduates to fulfil their apprenticeships and training."
Over the last 12 months six apprentices from Unity Kitchen outlets have worked in all sections of its busy cafes at Tooley Street, Firepower, Flapjacks, and Timber Lodge at the Queen Elizabeth Olympic Park.
They have been learning the essentials skills needed for their chosen careers. Some excelling in customer service whilst others demonstrated their culinary flair, all essential ingredients to ensure customers are happy and that the apprentices achieve their Level 2 NVQ Diploma in Hospitality Services. They also attended Westminster Kingsway College one day a week to achieve their functional skills qualification.
Unity Kitchen is also celebrating the achievement of its 12 trainees from New Horizons, Firepower, Café 311 and Jacksons Cafés. They have achieved a Level 1 or 2 NVQ Diploma in hospitality Services.
