The major purposes of the CSP are to expand opportunities for all students, particularly traditionally underserved students, to attend high-quality charter schools and meet challenging State academic standards; provide financial assistance for the planning, program design, and initial implementation of public charter schools; increase the number of high-quality charter schools available to students across the United States; evaluate the impact of charter schools on student achievement, families, and communities; share best practices between charter schools and other public schools; encourage States to provide facilities support to charter schools; and support efforts to strengthen the charter school authorizing process. CSP—Grants to Charter School Developers for the Replication and Expansion of High-Quality Charter Schools (Developer Grants) are intended to support charter schools that serve early childhood, elementary school, or secondary school students by providing grant funds to eligible applicants for the  replication and expansion of high-quality charter schools (CFDA number 84.282E).

States that are not eligible to apply for Replication grants are: Florida, Georgia, Illinois, Louisiana, South Carolina, and Tennessee. However, they may apply for Expansion grants.
