Our History

Our History

On March 8, 1911, a vision for inclusive excellence in education took root at the University of Illinois. Dr. William Bagley and a small group of forward-thinking educators founded Kappa Delta Pi (KDP), an honor society that would change the landscape of education forever.

In a time when other educational societies, like Phi Delta Kappa, explicitly excluded women, stating “There will never be the opportunity for the admission of women,” KDP chose a different path. From day one, we embraced diversity and celebrated excellence in all its forms.

Our founding principle was simple yet revolutionary: to honor and support all exceptional educators, regardless of gender, race, or background. This commitment to inclusivity has been our guiding star for over a century.

Key milestones in our journey:

  • March 8, 1911: KDP founded at the University of Illinois
  • June 8, 1911: KDP officially incorporated as an honor society in education
  • Today: KDP stands as the largest national honor society dedicated solely to educators

Our community now boasts:

  • 20,000+ active teacher members
  • 650 university and college chapters
  • Over 1 million distinguished alumni

Each year on March 8, we come together virtually to celebrate our Founder’s Day. It’s a time to honor our roots and recognize the outstanding leaders who embody the visionary spirit of our founders. Want to be part of this inspiring event? Email ceo@kdp.org to join us!
