Brickfield's Accessibility+ Toolkit is a collection of blocks, reports, and back-end processes that help educational institutions identify, fix, and maintain the accessibility of course content inside Moodle.
Examining a Simple Example Course
While you learn how to use Brickfield, it can help to have a simple, example Moodle course to explore and observe how Brickfield works.
CTLR has created a small faux Moodle course for VCC Employees called Sampling the Brickfield Accessibility+ Toolkit.

This sample course has already been scanned by Brickfield Accessibility+ plugin. It provides examples of common accessibility problems that you might encounter after scanning your own Moodle course.
Look in the "Accessibility+ Review" block in the block drawer on the right, to see a heads-up view of issues in this sample course.
