Our Mission

A dynamic community of independent schools in the Greater Delaware Valley and beyond, ADVIS enriches and sustains schools through advocacy, thought leadership, professional development, and networking opportunities. 

Operational Principles

  • Advocate for the unique and exceptional value of member schools and promote public awareness, understanding of and respect for independent education.
  • Provide thought leadership on significant issues and developments in education and how they impact leading excellent schools.
  • Provide exemplary professional growth opportunities and visionary leadership development programs for independent school leaders.
  • Inform and counsel leaders of member schools about administrative professional best practices.
  • Foster communication, positive collegial relationships and collaborative projects through forums for networking and the exchange of ideas among members.
  • Serve as the central resource for families to learn about the diverse options of our excellent member schools.
  • Establish positive relationships with local, regional and national independent school associations and other relevant organizations, colleges and universities.

Our Member Schools

  • Have varied missions and educational approaches.
  • All nurture strengths and interests, develop character, foster life-long learning and prepare your child not just for college, but for life. 

Our Website

  • Can assist you in choosing an independent private school that will match your child’s individual strengths and needs, and your family’s values, with the school’s learning environment and mission.


  • Accreditation is earned through a rigorous peer evaluation process, usually with one or more of the following agencies: PAIS (Pennsylvania Association of Independent Schools), NJAIS (New Jersey Association of Independent Schools), or MSAC&S (Middle States Association of Colleges and Schools). ADVIS policy dictates that member schools must be state licensed and, in most cases, accredited by one or more of the above organizations.

ADVIS Statement of Commitment to Social Justice, Diversity, Equity and Inclusion

  • ADVIS has an institutional commitment to the principles of social justice, diversity, equity and inclusion. In the conduct of its official business, ADVIS does not discriminate on the basis of race, religion, creed, ancestry, gender, sexual orientation, age, physical challenge, national origin, or any other characteristic.
