The training

From July 2022 to February 2025, Maudsley Learning will annually deliver fully funded training to 300 practitioners and 100 supervisors. CAARMS practitioners will be empowered over two training days to learn from core psychometric concepts, observation and skills practice through supervision and support and to upskill staff in in being able to deliver the assessment within early intervention services for psychosis. CAARMS supervisors will receive advanced training over one day, with one refresher day, to effectively supervise, evaluate and assess CAARMS practitioners to build sustainability and impact. All trainees will benefit from an annual networking event to promote sharing of good practices at the end of each training year. The training will be delivered remotely via a bespoke digital platform.


The eligibility criteria for training will be assessed prior to enrolling on the programme.
