The purpose of this RFI is to identify high-quality core instructional resources – including print, digital, and open educational resources (OER) – that support instruction in Astronomy as defined by the Science Georgia Standards of Excellence. Information gathered may inform a potential future RFP or district pilot for the 2026-2027 implementation cycle. To meet this purpose, providers are given the opportunity to submit information for review, although the District reserves the right to consider any and all resources for acquisition. The information requested is limited to a set of general criteria already established by the district. Providers are invited to submit resources for single or multiple grade levels/spans. If there are multiple sets of materials within a provider’s product, each set of materials should be submitted separately.
