A primary concern of the BDA is that the professional help available to people with dyslexia, of all ages and abilities, should be of a consistent high quality. Holders of AMBDA accreditation are recognised as specialists in Dyslexia/Specific Learning Difficulties (SpLDs); are qualified to conduct specialist diagnostic assessments; Exam Access Arrangements and to deliver specialist teaching programmes to learners with Dyslexia/SpLD up to and including 18 years of age.

The JCQ Access Arrangements criteria (7.3.4) for a Specialist Assessor map onto those for AMBDA.  Therefore, holders of AMBDA have the right to assess for,and diagnose Dyslexia/SpLDs and make recommendations for Exam Access Arrangemenst (EAA). When applying for AMBDA, after the successful completion of a BDA accredited course,applicants will also be eligible to apply for an Assessment Practising Certificate (APC) without additional training. 

AMBDA Applicants can also apply for a Teaching Practising Certificate (TPC); Approved Teacher Status (ATS) if they hold QTS/QTLS; Approved Practitioner Status (APS) if they do not hold QTS/QTLS.

Please note, AMBDA (Associate Member of the BDA) is not the same as Professional Membership, but AMBDA holders may also become Professional Members of the BDA; however APC (Assessment Practising Certificate) holders must also hold Full Professional Membership for the duration of their APC.

 AMBDA Accredited Courses

The BDA does not run Post Graduate courses but accredits PG Level 7 courses through universities and other Course Providers. Most AMBDA courses cover teaching in the first year and assessment in the second year.
