Schools and school districts are data-rich environments, with heaps of data on student demographics, achievement, outcomes, and perceptions. With so much data available, it can be easy to get caught up in the sheer enormity of the data sets. A cohesive data analysis and decision-making process can help schools, districts, and additional stakeholders to ask good questions, sort through the available data, identify which figures are needed to answer the questions at hand, analyze the data and, ultimately, use the information gained from the analysis to make good decisions and carry out meaningful action for school improvement. Before a school or district begins to organize data around identified questions, it is important to designate a group of individuals within the organization who will hold primary responsibility for organizing, analyzing, and coordinating responses informed by the data. This group becomes the data team. At least one week prior to beginning their work together, all members of the data team should receive and review a copy of the guidebook to ensure that all members share a basic understanding of the process they will follow during the ensuing meetings. Every multi-member data team should have a facilitator to guide the team through the process and to keep the team on task. This Facilitator's Guide provides suggestions, instructions, and tips for a team facilitator to lead a group through the completion of each stage of the data analysis and decision-making process. The guide corresponds with the "Using Data to Guide Action for School Improvement" guidebook. The following appendices are included: (1) Data Team Roles & Responsibilities; (2) Common Education Data Sources; (3) Methods of Calculation; (4) Facilitator Reflection Questions; and (5) Organizational Tools.
