The Learning Institute The Learning Institute (TLI) is an organization based in Hot Springs, Arkansas that helps districts use data to establish processes in order to improve student achievement and design formative assessments. These assessments measure the growth of students toward a long-term objective. In so doing, these assessments have allowed us to create a scope and sequence for current curriculum, discover holes in this curriculum, designate areas where supplementation is required, identify appropriate supplementary materials and methods, and adjust instructional plan and curriculum processes.
