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:
“Teaching Lab was one of the best PD’s I’ve had in my 31 years of teaching. It presented systemic changes that could be made in mathematics instruction that work. It wasn’t focused on quick fixes or cute lesson ideas.”
Teacher in Strive/Cincinatti Public Schools
“One of the reasons we went with Teaching Lab is because of its emphasis on content specificity, curriculum specificity, as well as equity. So we were looking to promote a coaching model that was transformational. The Head, Hearts, and Habits really spoke to us and said that this is ultimately what we needed.”
Amy Baker-Sheridan, Associate, Secondary English Language Arts & Literacy, Delaware Dept of Ed
“This learning community is, by far, the most beneficial I have ever been involved with. I’m very thankful for my PD time with Teaching Lab.”
Teacher in Washington Parish, LA
“Relay has consistently delivered high-quality adult learning that simultaneously holds our educators’ full-selves, anchors on a rigorous and belonging student experience, and results in tangibly better-empowered teachers.”
Caitlin Butler, Deputy Chief of Talent, KIPP Texas
“Our relationship with Dr. Soto [of Teaching Lab] has made all of the difference in the success of our professional development. She has been outstanding, and my principals and leaders ask for her specifically by name.”
District Leader in Calcasieu Parish, LA
“This learning community is, by far, the most beneficial I have ever been involved with. I’m very thankful for my PD time with Teaching Lab.”
Teacher in Washington Parish, LA
“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.”
Tamara Leachman, a CPS 3–5 math teacher
“I’m really excited about all of it to be honest but specifically our problem of practice has been rigor so it will be exciting to see high expectations for ALL students with this program.”
