• Assessment & Feedback: Proctor assessments, review daily student work, and leave clear, constructive progress notes for returning classroom teachers.
• Campus Life & Supervision: Conduct essential daily supervisory duties (recess, lunch, library, theater, morning/afternoon duty) to maintain student safety across campus.

Qualifications & Skills

• Education: Bachelor’s degree in Education or a related academic discipline (Master’s preferred).
