This fourth and final brief about the Fresno-Long Beach Learning Partnership looks at the ways that two districts push one another to deepen the culture of data use within and across districts, address infrastructure challenges and provide support as they navigate public conversations about student outcomes. This example of collaboration can inform schools and districts across the country as they develop tools and processes to access and use data for decision making. The brief demonstrates how two districts are building their collective capacity to look at student outcomes and leading indicators such as course transcripts and formative assessment scores to uncover root causes for achievement patterns and develop solutions to common challenges. This brief concludes the series documenting the Fresno-Long Beach Learning Partnership. For an overview of the series and a summary of key themes and implications, please visit the link below.
