Is there a requirement to cover and hide academic content (e.g., posters, etc.) when testing in the classroom (like requirements for other state tests, such as the PSSA)?

Since ACCESS does not assess content, it is not necessary to cover or remove anything that would provide an advantage purely for content (e.g. a periodic table or math formulas). However, as stated on page 37 of the Test Coordinator Manual (in the WIDA Secure Portal under “resources”), you should remove any posters that could assist students with language (e.g. grammar posters, color charts, classroom labels, etc.).
