- 3 Levels: A, AA and AAA

- POUR principles

- Critical Failures: Checkpoint 1.4.2, 2.1.2, 2.2.2

Accessibility problems on Thai university websites

Possible causes: Lack of awareness, lack of policy and lack of WCAG 2.0 implementation, testing and knowledge

Recommendation – the Thai government strengthen its policy and requirements around accessibility of online technologies.
