The Checkpoints

Each of the checkpoints defined in the WCAG document are presented here in one of three tables; Tables 7.1 through 4.4 show the checkpoints for each priority level. The tables are organized by priority and include the feature that the checkpoint covers (general issues, images, and so on) and the instruction.
