"The OGMIUS project is the result of the collaboration between three theatre companies working with learning-disabled (LD) professional artists. These three producing and touring companies, which have been operating for more than 30 years, also offer professionnal training for LD people, with little to none equivalent in mainstream training programmes. After the success of their first European project, Crossing the Lin (2014-2017), the three partners have decided to join forces and focus on improving training opportunities for LD actors by:1. sharing existing approaches to training and LD artists support, 2. designing a common and transferable tool for LD artists to evaluate and self-evaluate professional practice and skills, 3. compiling the evidence and learning from this project to work towards a European certification;4. reducing the gap between mainstream VET for non-LD artists and LD artists; 5. creating a transnational work force of suitably skilled support workers (educateurs); 6. raising the profile of professional training for LD artists among the wider arts sector.OGMIUS has gathered more than 60 LD artist, 12 support workers or ""éducateurs"", 3 technicians, 6 guest artists and facilitators, 14 staff members and managers. Over 100 people have taken part, directly or indirectly, to the project activities. 10 training (3 virtual), 4 transnational project meetings and 2 multiplier events activities were realised.The partners have conceived three intellectual outputs:- one open educational ressources collection from data gathered during training activities;- 9 filmed documents;- 1 good practice guide including two evaluation and selfevaluation tools created and tested during the project, the ""doodle book"" and the ""photo-elicitation"" method.The project has enabled the partners to share their experience and expertise in terms of creating and operating training for LD artists and to improve their respective processes. The ""éducateurs"" or support workers from the three countries benefited from the experience and said it has had long-lasting impact on their practice. The partners have connected with mainstream organisations: University of York St John, the Université d'Artois, the City of Malmö...Nearly 350 people attended multiplier events. The ""doodle book"" was distributed in the UK during the lockdown (3,500 copies). Partners have shared the project with more than 120 organisations from the so-called ""art and disability"" sector.OGMIUS has enabled the partners to start long-term projects which will last beyond the project: the certification project led by Mind the Gap and the University of York St John and the creation of a performing art school by Moomsteatern with the City of Malmö.Despite the complex circumstances caused by the Covid crisis, the partners have moved collectively to reach the project objectives and improve the training opportunities for LD people."
