There are three levels of WCAG conformance: A, AA, and AAA. Each level builds on the previous level like a pyramid. So, in order to meet Level AA, you must meet all of Level A, and in order to meet Level AAA, you must meet all of Level AA.

• Level A: This level represents the base level of conformance. Level A criteria affect the broadest group of users with the most benefits and are essential. But, with the base level of support, some barriers will still exist that impact certain groups of users.
• Level AA: This level is the most common target conformance level, often adopted in regulations or negotiated in legal settlements. The criteria at this level establish a level of accessibility that works for more users, including those who use assistive technology.
• Level AAA: This is the highest conformance level achievable, meaning it covers the success criteria of all three levels. However, level AAA is not applicable or realistic in all situations. Some organizations may choose to adopt specific criteria at this level.
