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.

Face to Face Assessments

If you are looking to carry out assessments at the current time, we need to refer you to the SASC guidance on their website. Assessors are recommended to send out their own risk assessment and follow all government guidelines in regards to safe practices.

Update on Face to Face Assessment - 22nd October 2020

The BDA has made the decision to postpone assessments in areas which are highlighted by the Government as high alert or very high alert/Tier 2 or 3, where there is an increased risk of transmission. The BDA takes the health and safety of assessors and clients very seriously. The decision to postpone assessments takes into account the proximity of client and assessor during assessments done in person. Therefore, our advice to Professional Members is to check the Government guidelines in your area and make decisions around continuing professional activities, based on that guidance and your own personal circumstances.
