DDA Compliance

Hi, i'm currently reviewing the DDA compliance requirements for our business in relation to e-learning development, and I was wondering if I could get some advise / guidance on how best to approach this.

In addition, there is a need for the courses being delivered being DDA compliant so any suggestions on best practices in how to create compliant courses will be really appreciated.  Just to advise, we have screen readers in some areas of the business so interested in how these can be engaged for the delivery of training.
