Funding

How South Dakota funds schools

South Dakota funds districts through a General State Aid formula built on a target teacher salary model rather than a flat per-pupil amount: the state divides each district’s enrollment by a target student-to-teacher ratio, multiplies the resulting teacher count by the statewide target salary ($62,821 for FY2026) plus benefits and overhead, subtracts the district’s local effort from the general-fund property levy, and pays the remainder as state aid.

District-level per-pupil spending and the local/state/federal revenue split for Castlewood School District 28-1 are published in the federal school-finance files — see the full-data links below for the current figures.

Accountability

Report card & state results

South Dakota publishes the ESSA-based South Dakota Report Card, reporting the School Performance Index along with proficiency, growth, English-learner progress, graduation and attendance. Look up Castlewood School District 28-1 on the South Dakota Report Card portal.

Accreditation

Accreditation status

South Dakota accredits public districts itself through the Department of Education on a five-year review cycle under Administrative Rule 24:43, separate from any voluntary Cognia accreditation a district may also hold. See the South Dakota DOE accreditation pages.
