Education Pioneer School Improvement Network Invented the On-Demand Professional Development Industry, and 20 Years Later Still Leads It

We’ve spent many years now producing hundreds of instructional videos for educators. We didn’t know it at the time, but what we were doing was absolutely re-inventing the professional development industry.

What started in 1991 as a science teacher’s pet project has now become the biggest online library of professional development videos for educators in the world.

That science teacher, School Improvement Network co-founder John Linton, began his teaching career frustrated by the lack of guidance he received from his leaders and colleagues. Linton spent much of his first year wandering the halls of the school, eavesdropping on other teachers. “I just wanted to hear what was going on in other classrooms. I even felt a little guilty, ” he says.

Linton’s experience, though, ended up being more positive than he anticipated, as he learned how to improve his own class by watching other teachers in action. His colleagues quickly took notice of the new science teacher wandering the halls, and soon, Linton was allowed into their classrooms to film what he had only watched before. As interest grew in Linton’s project, his wife Blanch Linton, also a teacher, joined with him to establish the Video Journal of Education, now known as School Improvement Network.

“We began traveling, filming teachers all over the US in their classrooms,” says Linton. “Soon, we had enough footage to complete several programs, and these launched us into the business. We’ve spent many years now producing hundreds of instructional videos for educators. We didn’t know it at the time, but what we were doing was absolutely re-inventing the professional development industry.”

In 2007, School Improvement Network placed its video offerings online, becoming the first company in the world to offer on-demand professional development. Today, School Improvement Network has taken their ever-growing array of videos, their online community, and stable of education experts, and built a comprehensive online professional development platform called PD 360.

And in April of 2012, celebrating 21 years since John and Blanch founded the company, School Improvement Network announced that by the end of the year, PD 360 would grow to include more than 2,000 videos—over 300 hours of footage.

“What started with my parents has grown into the largest online PD video library for teachers in the world,” says Chet Linton, current CEO of School Improvement Network, and John and Blanch’s son. “We now have dozens of hours of video training on classroom management, differentiation, and the Common Core State Standards, among other topics. Our community of educators is 822,000 strong and growing, and is committed along with us to getting 100% of students college and career ready.”
