Educators care about instructional materials because students learn more when their classroom resources are high quality. Yet, until recently, teachers and administrators lacked credible, third-party information on the quality of instructional resources under consideration. Recently, the landscape has shifted as non-profit organizations and universities have launched tools designed to help educators evaluate instructional materials. This EdWeek Research Center survey found that educators who use the most popular source, EdReports, are highly satisfied with the tool, expressing confidence in its standards and evaluations. Educators are also very focused on two areas not captured by third-party review sites: student engagement with challenging content and support for high-quality implementation.
