Empowering Educators. Impacting Students. Strengthening Communities.

At SimpleK12, we believe that when teachers grow, their students thrive. For over 40 years, we’ve been on a mission to make professional learning accessible, flexible, and truly impactful—for every educator, in every type of learning environment. 

We’re more than just a modern professional development platform. We’re a trusted partner to teachers, schools, and districts across the country—delivering expert-led, self-paced professional learning designed for real classrooms and real challenges. Our course library includes over 1,000 on-demand courses across 40+ relevant, researched-based categories, each built to support growth, confidence, and instructional excellence. 

Every educator we serve helps shape stronger, more resilient school communities. Whether you’re a first-year teacher navigating the classroom for the first time, a small private school principal, or a seasoned district leader seeking scalable solutions for a large school district, SimpleK12 meets you where you are, and helps educators move forward with purpose.  

We’re proud to be backed by The Rise Fund, a global impact investment firm. That means our goals go beyond revenue—we're focused on driving measurable educational outcomes, expanding equity, and creating lasting social good. 

Join us. This isn’t just professional development. It’s a movement to uplift educators and transform classrooms—because when you grow, your students do too.

Welcome from our director

Dear Educator, 

At SimpleK12, our purpose is to support teachers with professional learning that’s accessible, flexible, and designed to make a difference—both in the classroom and throughout a career in education. 

For over 40 years, we’ve helped educators grow their skills, explore new strategies, and stay current in a profession that is always evolving. Our platform offers on-demand access to research-based courses that reflect the real challenges and opportunities teachers face every day—and new content is added weekly to keep learning fresh and relevant. 

Whether you’re just beginning your journey as an educator or continuing to expand your expertise, SimpleK12 is here to support you. We believe that learning should be practical, inspiring, and built around your goals—not a one-size-fits-all experience. 

We’re honored to be part of your professional learning story, and we can’t wait to see where it takes you.

Warmly,

Caitlyn Luberger
Director of Professional Development
