可访问性

PG电子游戏官站 is committed to delivering an online experience that is as accessible as possible for the widest range of visitors, 包括那些使用适应性和辅助技术的.

The University is striving for at least AA compliance with Web 内容 可访问性 Guidelines 2.0 (WCAG 2.0) but acknowledges that some content may not yet meet the requirements for AA compliance.

WCAG 2.0 uses a three-level rating system to identify the level of accessibility. 在WCAG 2.0, level Single A (A) is the basic, moving through Double A (AA) and Triple A (AAA). Even at Triple A conformance, some users will still experience some difficulty in accessing content.
