Substitute Services

The Columbia County School District is dedicated to employing a substitute workforce capable of continuing the commitment to excellence and serving our students during times of employee absence.

We are only accepting substitute applications from certified teachers at this time. We will begin accepting applications from non-certified substitutes beginning July 1, 2024 for the 2024-2025 school year. Thank you for your interest in the Columbia County School District.
