Upper School at St. Joseph Catholic School encompasses 5-8 grades. Subjects are taught in a departmentalized system. Students are provided a diverse curriculum, which uses the Archdiocese of New York "Essential Learnings" for overall guidance.

Learning objectives are a culmination of the Essential Learnings and the assessment provided by each Upper School teacher. The I.T.B.S. standardized test scores indicate this is a successful approach to the St. Joseph School curriculum development and implementation.
