How to become a dyslexia assessor

Assessment Practising Certificate (APC)

What is an APC?

An Assessment Practising Certificate (APC) recognises the knowledge and skills of specialist teachers who have followed an appropriate course of study (e.g. an AMBDA accredited course or a course recognised by SASC) and can demonstrate their professional competence in the assessment of specific learning difficulties/dyslexia.

In November 2018, the Department of Education (DfE) announced that a diagnostic assessment conducted at any age, which results in a diagnosis of dyslexia, will be accepted as part of an application for Disabled Students' Allowances (DSA). However, these reports will only be accepted if written by an assessor holding a valid APC at the time of the assessment (or an HCPC psychologist). As reports conducted at any age may be used for DSA purposes, it is recommended that all assessors should now hold an APC, to future proof assessments for dyslexic individuals so that no further assessment will be required.

An APC is valid for three years from the date of issue. APC holders must also hold a professional membership of the issuing body for the duration of the APC; the APC will be invalid should the membership lapse.

Associate Membership of the British Dyslexia Association (AMBDA) is now the professional membership required for all those applying for and holding an APC issued by the BDA. Your APC will be invalid should your AMBDA lapse during the period of the APC.

Those holding an APC must commit to continuing professional development (CPD) and the BDA Code of Ethics.

Who can apply?

You may apply for an APC if you:

If applying before 31st March 2020, SASC has agreed to lift the requirement for applicants to submit a diagnostic report if they have completed a course over five years ago. If you have completed an AMBDA accredited course or equivalent at any time, and can supply evidence of this, you will now be able to apply for an APC and AMBDA up until 31st March 2020, even if you have not previously applied for AMBDA or an APC.

If you have previously held an APC, with any of the issuing bodies and your APC has lapsed, you should renew through the normal renewal route by supplying a CPD log and a full diagnostic assessment report written within the last 18 month which meets SASC guidelines.

If applying after 31st March 2020, applicants who have completed a course more than five years ago, will need to submit a log of relevant CPD completed within the last 3 years, and a full anonymised diagnostic report for review.
