The TEACH Act, also known as the Technology, Education and Copyright Harmonization Act, is an additional set of conditions under which copyrighted materials may be used under special circumstances. It is a separate consideration from Fair Use. Anyone trying to use the TEACH ACT must come from an accredited, nonprofit educational institution and must be using the materials in distance education.
