Question 2

Please follow the directions below and then select the correct option:

  • Open a new browser window.
  • Launch the readability test tool.
  • Once you have opened the tool, evaluate the following block of text (do not include the quotes surrounding the paragraph).
  • Determine the overall reading grade level required to effectively understand the paragraph.
  • Select the average grade level range from the list below.

“Though reading level is a Level AAA requirement in WCAG, this is one Level AAA guideline that most public sites should aim for to reach the broadest possible audience. Generally speaking Web content authors should use the simplest language possible (within reason). Simple text will translate more easily for those who may wish to read the site in a different language. It will be more accessible to those with lower levels of education, or for those reading in a second language. And for a general audience, most readers will appreciate simpler language over unnecessary use of “big” words. Being able to explain things in simple language for most, is a more intelligent use of language than loading it with jargon, complex terminology, and unnecessarily complicated words and sentences.”
