The CMSE Middle Math Institutes were designed and proposed to the Mississippi Department of Education to serve as an alternative pathway to obtain a Middle Level Mathematics Endorsement (901). This pathway is available to any educator who holds a valid Mississippi teaching license regardless of current endorsements. For many years, the Mississippi Department of Education issued grants to fund math and science professional development institutes through the Math Science Partnership (MSP) funding that was appropriated through the No Child Left Behind federal legislation. MSP projects throughout the state provided an opportunity for elementary and special education teachers to add supplemental endorsements in middle level mathematics or science by completing project components. These programs ended in 2018, leaving Praxis and mathematics coursework as the only pathways for educators to add a supplemental endorsement in middle level mathematics (901).
