"BDA Assured"
 BDA Assured was a programme run by the BDA from 2019-2021 which gave the “BDA Assured” badge to resources that were recognised by the BDA as being helpful to people with dyslexia.  During that time, Crossbow reading rulers and coloured overlays were part of the scheme.  This programme has now been discontinued, and will be replaced early in 2022 by a new page of useful resources.
