About the School

  • Saint Aidan, a Roman Catholic elementary school, serves our parish and the surrounding communities by educating students from nursery school through eighth grade.
  • We offer a quality program of instruction in a Christ-centered environment to encourage and guide children to become lifelong learners and committed members of both our society and of our Catholic Christian community.
  • Education at Saint Aidan School focuses on the development of the whole student.
  • The academic program is based on standards established by the New York State Board of Regents and by the Education Department of the Diocese of Rockville Centre.
  • Faculty, staff, and administration strive to develop, to examine, and to implement sound educational practices that afford students opportunities to master content to the best of their abilities.
  • Teachers recognize and honor the varied aptitudes and talents of our students, and endeavor to adapt the standards to accommodate a range of learning styles and student needs.
  • Beyond the standards, students are encouraged to think critically and creatively as they look toward their academic advancement, their vocations, and their avocations.
  • The faculty of Saint Aidan School consistently infuses the curriculum with Gospel values.
  • Acknowledging a parochial school's unique opportunity “to teach as Jesus did,” we encourage growth in faith and spirituality throughout all grade levels and disciplines.
  • Saint Aidan's faculty, staff, administration, pastoral staff, and families collaborate to provide and to sustain an environment where children can learn about, practice, and live their faith openly.
