Welcome to the East Rochester Union Free School District. We are proud of all that we offer in ER. From excellent academics to diverse extra-curricular offerings, we provide a supportive, enriching environment that allows all students to thrive. Our single UPK-12 campus allows for cross-grade activities and our community partnerships add to the ER Family atmosphere. With small class sizes and a consistently high graduation rate, ER students enjoy many opportunities to achieve their goals. We are...ER.
