Our History

CT3, founded as The Center for Transformative Teacher Training, was established in 2009 by acclaimed educators Lee Canter and Kristyn Klei Borrero. The company was formed in response to the countless requests they received from educators around the country to provide training in their breakthrough model of professional development.

CT3 is redefining what constitutes highly effective professional development with its unique training model that delivers feedback at the point of instruction, Real Time Teacher Coaching®, and with its research-validated method for classroom management, the No-Nonsense Nurturer® Program.

Our Mission

CT3 transforms the quality and culture of education for youth, especially those in traditionally disenfranchised communities.

Our Vision

Become the MOST EFFECTIVE professional learning organization: building capacity WITH our partners to implement anti-racist practices and dismantle the systemic structures that have historically impeded self-confidence and academic outcomes among historically disenfranchised youth.

At CT3, we believe…

… every child deserves a world-class education from teachers who are dedicated to student well-being and success.

… teachers who learn about, honor, and leverage the cultural knowledge, experiences, and frames of reference of their students—and their students’ communities—make learning more relevant and effective.

… all students are capable of engaging with challenging curriculum and can meet or exceed rigorous expectations.

… building positive relationships, culturally relevant practices, and empowering mindsets are essential when serving youth.

… students thrive in classrooms where they feel safe, valued, cared for, and have a sense of membership and investment.

… an asset-based school culture where feedback is transparent and in real time supports high levels of achievement for educators and students.

… every teacher can be a positive role model and change agent in students’ lives and has the ability to become a No-Nonsense Nurturer.

… a successful school leader is THE agent of change for a school.
