In South Carolina, a charter school can be established in one of the 86 county-based school districts or in the South Carolina Public Charter School District (SCPCSD). PSA is part of the SCPCSD. As such, PSA can enroll students from any county.
Charter schools are simply another form of public schools.
Like public schools, charter schools are:
Required to meet state and federal laws
Within a public school district and accountable to its board
Required to participate in SC standardized testing
Charter schools are different in several important ways:
Are governed by a board of school-elected parents, teachers, and community members
Can solicit and accept donations and gifts as a non-profit corporation
Have control over their class size, curriculum, discipline code, and employment practices
Are accountable to meet the objectives set forth in their charter
