The purpose of this Request for Proposals (RFP) is to select a third-party contractor to deliver equitable supplementary educational services (ESES) in the areas of reading, mathematics or science, to Title I eligible students enrolled in non-public schools, as well as professional development and parental involvement activities in support of these students, their teachers, and families. These services must comply with all federal and state program requirements and must take place during the school day (unless otherwise requested by the participating non-public school and approved by MDCPS) throughout the school year. The provider(s) selected must be able to customize the instructional services, professional development and parental involvement activities to meet the needs of eligible students, their teachers and families, respectively. These contracted equitable supplemental educational services are not NCLB Supplemental Educational Services (SES), which are individualized tutorial services that occur beyond the regular school day/week, and are funded under separate grant funds, and do not require professional development and parental involvement activities. No additional specifications were given.
