An Extended School Year (ESY) job involves working with students who require special education services beyond the regular school year to prevent regression in critical skills. ESY staff, including teachers, paraprofessionals, and therapists, provide instruction and support based on individual student needs, often following an IEP (Individualized Education Program). These positions are typically temporary, lasting for a few weeks during the summer. Responsibilities may include assisting with academics, life skills, and behavioral support in a structured setting.
