Completed the ADHD assessor course and I am more than happy to recommend it to anyone. Amazing experience.
The trainers are thorough, knowledgeable, caring and passionate. Highly qualified trainer with professional and personal experience, which makes the course even more fascinating.
Happy to help and share their knowledge, engaging all students in discussions.


I really enjoyed the training delivered by Sarah. She created a safe space throughout the training which supported people to share their lived experience and ensured a neuro-affirming approach to assessment was prioritised.


I recently completed a five-day online ADI-R and ADOS training delivered by Sarah, Areeba. The course was exceptionally well structured, informative, and engaging throughout.
Sarah’s depth of knowledge and her ability to explain complex concepts with clarity made the content accessible and practical. She created a supportive learning environment where every question was welcomed and thoughtfully answered.
The standard of delivery was excellent, professional, approachable, and interactive. I would highly recommend this training to anyone looking to develop their understanding of ADI-R and ADOS.


Fantastic training course . The expert training you get from the autism service group is by far the best training around. The wealth of knowledge and commitment to this course by Sarah Phelan and her amazing dedicated staff goes beyond professional commitment. I would recommend anyone who wants to do any training course to work with ND to contact the autism service group first.
