The catering and bakery training courses are provided by Providence Row, a charity that works with more than 1,400 homeless and vulnerably housed people a year in east London.
Peter Ducker FIH, chief executive, Institute of Hospitality, said: "Endorsement by the Institute of Hospitality demonstrates that Providence Row's training courses meet a wide range of essential criteria and benchmarks relating to quality standards and quality learning outcomes."
Providence Row has been running the Catering Trainee Scheme for the last seven years, having worked with over 200 trainees, food designers, and nutritionists and over 20 professional chefs at Andaz Hotel Liverpool Street and other catering establishments.
The charity has two full-time chefs with catering backgrounds. In addition, Andaz Hotel Liverpool Street provides workshops and work experience placements for trainees.
Dominic Gates, enterprise and training manager, Providence Row, said: "We're absolutely thrilled to gain this prestigious endorsement as it's a fantastic acknowledgement of our team's great work offering catering and baking training to people affected by homelessness, substance misuse and mental health issues.
“In the last seven years, we've developed a traditional 'soup kitchen' into a supported training kitchen, offering people quality training to help them move away from homlessness and back into employment."
