Is it permissible to use copyrighted works (e.g. literary excerpts, photographs, etc.) for teaching purposes?

Yes. There is an exception that allows teachers and professors to use copyrighted works for the purpose of illustration in teaching, including for testing and assessment, when such use takes place in a classroom or other teaching context. The use must be non-commercial, limited to the educational purpose, and the source and the author of the work must always be properly acknowledged. This exception is important, as it enables effective teaching and learning without the need for teachers to obtain permission from the rights holder for each individual use of copyrighted material.
