Q: What teaching materials can be posted on walls during SAGE and similar testing?
A: The following information was taken from USOE FAQ on testing ethics for 2014:
Teaching materials (e.g., posters, banners) that are generic in nature, have been used for general instruction throughout the year, and do not provide answers to test questions may be left in place. Teaching materials that are meant to artificially inflate assessment scores (e.g., applicable to specific test questions) should not be visible to students.
