No - is the short answer.

However Training in Learning Disabilities and Autism is Mandatory.
In 2022 the Health & Care Act 2022 came into place (not much noise was made about it) and in section 181 it states the requirement for all registered Health & Social Care organisations to have training in Autism and Learning Disabilities.

As part of that Health & Care Act 2022 it also states that a Code of Practice will be developed along side this to highlight the standards and requirements for the provision of training regarding Learning Disabilities and Autism. 

The Oliver McGowan Code of Practice on statutory Learning Disability and Autism Training has closed its consultation and has not been published as final draft, (presumably the shift in political leadership has slowed this). There is a section on this with highlighting the standards and guidance on meeting the standards. 

What does CQC say? "The Oliver McGowan Mandatory Training is the government's preferred and recommended training for health and social care staff to undertake to enable providers to meet the requirements of this regulation." - Training staff to support autistic people and people with a learning disability - Care Quality Commission (cqc.org.uk)

Much like other subjects in training and other requirements such as health & safety the organisation must deem what it sees as "reasonable" to meet these standards, if you do not adopt any form of the Oliver McGowan training, be prepared to answer the question of "Why?" and "What are you doing to meet the need for training in Learning Disabilities and Autism?".

It is widely thought that the brand of "Oliver McGowan" Training will be the one and only acceptable curriculum of training however this is not the case at this moment in time.
