E3 Alliance is a regional, data-driven education collaborative based in Austin, Texas. They are helping to build the strongest educational pipeline in the country to drive regional economic prosperity. They are focused on educational systems change, and use data to inform those efforts. Given that their approach to supporting educational improvement is fundamentally 'data driven', data from the University of Texas Education Research Center (ERC) plays a key role in their ability to provide objective, actionable data to practitioners in the region. E3 Alliance has developed a comprehensive set of education and related workforce statistics over the past decade that provide the region with critical information necessary to understand the education and related workforce issues facing the region, to develop well-grounded strategies in response, to change instructional policies and practices, and to allow the assessment of progress over time. Each year, E3 Alliance produces the Annual Central Texas Education Profile, the most comprehensive regional view of educational trends and outcomes in Texas. A key priority of their work has always focused on early learners. E3 Alliance's early childhood research includes (1) creation of "Ready, Set, K!," a Kindergarten Readiness Assessment designed to measure children's Kindergarten Readiness across the Social-Emotional Development, Emerging Literacy, Language and Communication, and Early Numeracy domains; (2) the Kindergarten Readiness Study, launched in 2010 to determine what portion of Central Texas children enter kindergarten ready for school using the "Ready, Set, K!" Assessment as well as factors associated with readiness (e.g. full-day, low-ratio Pre-K); (3) Longitudinal correlation of readiness with later outcomes including 3rd grade reading and math proficiency, and (4) annual updates to the Central Texas Profile, which tracks various early childhood education metrics.
