The government's healthcare watchdog, the Healthcare Commission, is calling for people in the learning disability sector to take part in an audit of learning disability services in England.
People with learning disabilities, as well as relatives, carers and those working in the sector are wanted to be peer reviewers in what is set to be the most extensive audit on the matter.
The probe will involve inspections of up to 200 services and will include data will be collected from over 600 services in England.
Peer reviewers, some of whom will be paid, will help lead the inspections and contribute to the report.
"We need people who are at the coal-face of the delivery of these services as well as the people who use them," said Fiona Ritchie, the Commission's lead for learning disabilities.
"Their work will be essential in identifying problems in the sector, highlighting examples of good practice and setting a higher benchmark for the delivery of quality services to people with learning disabilities."
The report is expected to be released by the end of the year.
