Testimonials
Teachers are the engine behind the success of our work to shift the paradigm of teacher professional learning. At Teaching Lab, educators’ voices matter – and we are honored to share those voices here:
“Our literacy scores at the elementary were higher than they have been in years. I feel the inquiry cycles that were facilitated by our instructional coaches (trained by Teaching Lab) were very influential in this growth.”
Teacher in Ft Dodge, IA
“I feel like I’m more confident and comfortable when I’m talking with other educators, knowing what I can support them with. The work we’ve done has given me the ability to recognize my strengths and how I can use those to support the other teachers I work with.”
