<h1>Introduction to Understanding WCAG 2</h1>
<p>Understanding WCAG 2 is an essential guide to understanding and using "<a href="https://www.w3.org/TR/WCAG/">Web Content Accessibility Guidelines 2</a>". Although the normative definition and requirements for WCAG 2 can all be found in the WCAG 2 document itself, the concepts and provisions may be new to some people. Understanding WCAG 2 provides a non-normative extended commentary on each guideline and each success criterion to help readers better understand the intent and how the guidelines and success criteria work together. It also provides examples of techniques or combinations of techniques that the Working Group has identified as being sufficient to meet each success criterion. Links are then provided to write-ups for each of the techniques.</p>

<h2>Layers of Guidance</h2>
<section>
<h3>The Guidelines</h3>
<p>Under each principle there is a list of guidelines that address the principle. There are a total of 13 guidelines. A convenient list of just the guidelines can be found in the <a class="gl-ref" href="https://www.w3.org/TR/WCAG/#toc">WCAG 2 table of contents</a>. One of the key objectives of the guidelines is to ensure that content is directly accessible to as many people as possible, and capable of being re-presented in different forms to match different peoples' sensory, physical and cognitive abilities.</p>

<h3>Success Criteria</h3>
<p>Under each guideline, there are success criteria that describe specifically what must be achieved in order to <a>conform</a> to this standard. They are similar to the "checkpoints" in WCAG 1.0. Each success criterion is written as a statement that will be either true or false when specific Web content is tested against it. The success criteria are written to be technology neutral.</p>
<p>All WCAG 2 success criteria are written as testable criteria for objectively determining if content satisfies the success criteria. While some of the testing can be automated using software evaluation programs, others require human testers for part or all of the test.</p>

<p>Although content may satisfy the success criteria, the content may not always be usable by people with a wide variety of disabilities. Professional reviews utilizing recognized qualitative heuristics are important in achieving accessibility for some audiences. In addition, usability testing is recommended. Usability testing aims to determine how well people can use the content for its intended purpose.</p>
<p>The content should be tested by those who understand how people with different types of disabilities use the Web. It is recommended that users with disabilities be included in test groups when performing human testing. </p>
