In partnership with nine States, the Department piloted a monitoring protocol on two related resource equity provisions under Title I, Part A (Title I) of the Elementary and Secondary Education Act of 1965 (ESEA)--(1) the requirement for States to periodically review resource allocation in LEAs serving a significant number of schools identified for comprehensive support and improvement (CSI), targeted support and improvement (TSI), and additional targeted support and improvement (ATSI) and (2) the requirement that CSI and ATSI plans both identify and address local resource inequities. This targeted monitoring effort helped the Department understand current practices, opportunities, and challenges when implementing these provisions. This letter outlines recommendations based on the Department's pilot and provides additional resources, tied to each recommendation, that may be helpful to States now that ESEA school improvement designations have resumed after most States received a waiver of accountability and school identification requirements for the 2020-2021 school year due to the COVID-19 pandemic.
