"Creative Commons is an international non-profit organisation that provides free licences and tools that copyright owners can use to allow others to share, reuse and remix their material, legally. Releasing material under a CC licence makes it clear to users what they can or cannot do with the material. The six standardised CC licences each allow material to be used in a different way." (Creative Commons Australia, 2015)
If you're looking for information in an online search engine like Google or Yahoo, you often find too much information and not all of it is useful (and some of it is just bad). The CAARP Test involves a series of questions designed to help students evaluate online information to determine if they should use the information for class projects, papers, or presentations.
