Born in the classroom. Built for the classroom.
The Center for Teacher Effectiveness was founded in 1993 by Rick Dahlgren — not in a university, not in a policy office, but in response to what educators kept saying they needed: real strategies, from people who had been in the room, that worked with today's students in today's schools.
What started as an answer to that question has grown into one of the most trusted professional development organizations in K-12 education. The content has always been the heart of it. When educators see and hear what we teach — the five core components, the research behind each one, the specific language and strategies — it sells itself. Not because it's clever marketing, but because it works.
Nearly all of our business is repeat and referral. School leaders tell colleagues. Teachers share with other teachers. Districts come back year after year. That's not an accident — it's the result of content that delivers measurable results, delivered by trainers who come from the profession they're serving.
"During my first two years as principal, we had over 300 office referrals and 150 out-of-school suspensions. After fully implementing these strategies — only two office referrals in six weeks."
"29 of our 35 schools were trained, affecting more than 11,000 children. We experienced a 16% decrease in suspensions and 9% increase in test scores."
