School Reviews
2 10/10/2025
Academics in the district are poor. Due largely to a too old, tired staff and administration. Extracurricular is largely sports and farming activities. Music and fine arts are suffering. Parent involvement would be better if central office administration would encourage them to do so. Current superintendent has no regard for public input.
