The Technology, Education and Copyright Harmonization Act (TEACH Act), an amendment to the US Copyright Act, was enacted in 2002 in response to technology advancements and the impact on distance or online education. The TEACH Act allows for exemptions when using copyrighted materials in online learning environments of nonprofit educational institutions. It DOES NOT replace or negate fair use, licensing agreements, and has specific criteria that must be met.
