Resources that are recommended by an Adventist Union or Conference education comittee are directly approved as CIRCLE database entries, noting the classification or recommendation. All other submissions by educators online or entries by CIRCLE staff are reviewed using the following guidelines.

CIRCLE's vision is to connect Adventist educators with quality curriculum and instruction resources of any type: printed, media, internet, or other. While resources such as lesson/unit plans, course outlines and handbooks may be in printed form, many are also available online. In such cases, both sets of screening criteria would apply.
