E-TEACH is a U.S. Department of Education grant to the Learning & Performance Support Laboratory (LPSL) at The University of Georgia (UGA). Evidence-based practices involve the systematic and purposeful use of performance data in differentiated decision-making, such as using LoTi profile progress of teacher educators to determine professional development, integration, and support needs, using pre-to-post indicators of the same profiles as evidence of the effectiveness of the support provided, and using state or local tests to establish evidence of learning needs and the effects of programmatic interventions to improve student learning.
