Getting hold of the 3di
An installer for the 3di software comes as part of a one or two day training programme. The courses have been delivered both in person and online. Once we have agreed a training date for you, we will arrange for the 3di software to be installed on your laptop which you must bring to the training. In NHS Trusts this step is performed by your IT department using instructions we provide, but self-installs are common too in private practice.
The course includes:
-
The 3di's dimensional approach to measuring the severity of autistic symptomatology.
-
Step-by-step tuition in the use of the interview software.
-
Simulation of the clinical use of the 3di by role-playing and the rating of videoed interviews.
-
DSM-5 and ICD-11: the 3di's effective implementation.
-
Reference material on the integration of the 3di with observational assessments of the child (eg ADOS).
The course fee includes:
-
The training course and materials.
-
An installer for the 3di software and a single-user license to the software version provided.
-
A year's technical support. First line support is via email, with telephone follow-up available.
The 3di is licensed on a per-user basis. Your entitlement to use the software stays with you if you move between employers. And once trained, you may use the software in more than one context, for example in both NHS and private practice.
Amongst those we have trained are paediatricians, psychiatrists, clinical and educational psychologists, special needs teachers, social workers, speech and language therapists, occupational therapists and specialist mental health nurses.
Bespoke courses
Where 10 or more professionals in a region are jointly interested in training to use the 3di we may be able to offer a local face-to-face event. However you would need to cover the trainer's (economical) travel and accommodation. Regional courses have proved to be a very good framework for bringing together the many different professions involved with ASD children — both in places where those professions already work closely and in places where greater coordination is an aspiration.
A commissioned face-to-face course delivers the same training programme, software licences, and post-course support as the original London courses.

Course dates
For individuals and small groups, we run training courses which are open to all and accept individual signups. These courses are delivered face-to-face in London, or online, depending on demand.
If you would like to be notified of these training opportunities, please leave your contact details below. We will only write to you when training places become available. We will not use your details for any other purpose or disclose them to anyone else.
Our next open training in May 2026 is now fully booked. We hope to organise a subsequent training in June or July 2026.
If you have any other query about the 3di, please email us at contact@ixdx.org.
