How to become a Dyslexia/Dyscalculia assessor and APC renewal

Assessment Practising Certificate (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.

As reports conducted at any age may be used for DSA purposes, it is recommended that all assessors should hold an APC, to future proof reports 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. All APC holders are listed on the SASC list of assessors.

Who can apply for an APC with the BDA?

You can apply through the website. This is called Route 1

You should apply through Route 1 plus - R1+

From 1st September 2023 applicants will need to submit the following:

  • Proof of current full professional membership of their APC issuing body (AMBDA)
  • A current CV to include details of relevant SpLD and assessment experience.
  • A CPD log evidencing a minimum of 30 hours of relevant professional development over the previous 3 years. The CPD log will include:
  • 1 - Evidence of 5 hours of SASC Authorised CPD. This is CPD that is authorised by SASC and listed through the SASC website. These SASC authorised CPD hours should not be updates on Access Arrangements, and
  • 2 - Evidence of 25 hours CPD which may or may not be SASC authorised, i.e., 25 hours of supplementary CPD over the three-year period.
  • A full diagnostic assessment report providing evidence of your independent assessment practice and produced within the last 18 months. The report must be fully anonymised.
  • A full set of anonymised working papers i.e., scanned copies of all the test record forms used in the assessment, including copies of the assessee’s written responses. All working papers must be completed in ink, preferably black, legible and clearly record the date of assessment and the name of the assessor (examiner).
