The CSSI team lead will provide the school leader a Document Review Checklist before the visit. The checklist is organized by standard. Team members will determine which documents are relevant to their assigned standards and review them closely. Documents are a valuable data source for triangulating evidence gathered from the other two sources; however, something cannot be triangulated alone just within the document collection; evidence of practice must also be present in stakeholder interviews and classroom visits. Schools are asked to share these documents in a digital format such as Google Drive or thumb drives as much as possible; however, schools can select to provide the CSSI team with hard copies of documents in a binder. It is most effective when schools organize the requested documents by standard and provide a direct link to the document within the Document Review Checklist.
