James Madison High School Teachers

Certified Teachers Help Students Succeed

All James Madison High School teachers are state-certified. The certification process requires specific coursework, a minimum of a bachelor's degree, teaching experience, and passing an approved, state-mandated teaching examination. Certification can only be attained once this rigorous criteria is met.
