Online Journals. Bibliography. References. Web-pub. Purdue OWL. Coming Soon: A new look for our same great content! We're working hard this summer on a redesign of the Purdue OWL. Worry not! Our navigation menu and content will remain largely the same. Grammar and Spell Checker. Readability tests. Readability tests and readability metrics are a way to measure the reading ease, comprehension, retention, reading speed, and reading persistence of a text.
We do not write the same way for an audience of 14-year olds or marketing specialists, for a scientific meeting or in a consent form in a hospital. Those tests will help you know if your writing meets your audience and your goal. The readability and grade level tests results are only valid according to the language of your text. When the language of your text is detected, it is displayed on an orange background. For the other supported languages, the results given are a mere approximation.
