The Technology, Education, and Copyright Harmonization Act (TEACH Act) says that teachers and students at accredited educational institutions can use works for distance learning without permission under certain circumstances.

If you:

• are an educator at an accredited educational institution,
• will supervise your students’ use of copyrighted materials,
• are using the material as an integral part of a class session,
• are using the material as an integral part of your curriculum, and
• are using the material that is directly related to and of material assistance to your teaching content,

and you plan to use copyrighted works in the following ways:

• performances of nondramatic literary works (i.e., a recording of a novel being read aloud);
• performances of nondramatic musical works (i.e., a recording of a symphony);
• performances of reasonable amounts of any work (i.e., an excerpt from a movie); or
• display of any work in an amount comparable to what would be used in a live classroom.

then your use aligns with the Teach Act.
