Teachers Development Group

What Teachers Development Group does

Teachers Development Group (TDG) is a 501(c)(3) nonprofit founded in 1998 and headquartered in Portland, Oregon, that delivers professional learning services to PreK-12 schools and districts nationwide, with an exclusive focus on equity-oriented mathematics instruction. Its service portfolio comprises five core offerings: Math Teaching Studios (real-time classroom-based learning for teachers and leaders), Math Coaching Studios (hands-on practice for coaches and teacher leaders), Math Content & Pedagogy Seminars (research-based content series), Instructional Leadership in Math Seminars (training for principals and district leaders), and one-on-one/small-group Coaching. The portfolio is unified by TDG's proprietary Math Habits Tool, a research-informed framework that codifies student habits and teacher routines/actions; the framework is also offered as a stand-alone iPad application on the Apple App Store.

TDG's underlying technology is a content- and pedagogy-led methodology rather than a software platform, with the Math Habits Tool serving as the unifying intellectual property across all engagements. Services are delivered by a national network of Math Professional Learning Specialists who hold Masters or PhDs in Mathematics Education and have prior PreK-12 teaching experience. Distribution is direct: TDG partners with school and district leaders to design tailored professional learning plans and delivers them on-site. Revenue is generated primarily through professional services contracts with districts and through foundation and federal grant funding, including multi-year Research-Practice Partnerships with the National Science Foundation, Heising-Simons Foundation, and Philanthropic Ventures; minor revenue comes from the Math Habits Tool app. Pricing is not publicly disclosed and is established via custom quotes per engagement. The organization is governed by a board of national leaders in mathematics education and has been led by CEO Ruth Heaton, Ph.D., since August 2017.

Broad incumbents

• WestEd: WestEd is a nonpartisan, nonprofit research and development agency that works on K-12 math and science improvement, teacher professional learning, and district capacity building. It is a broader incumbent that overlaps with TDG in math PD and NSF-funded research-practice partnerships.
• Education Development Center (EDC): EDC is a global nonprofit that designs, implements, and evaluates programs in education including STEM/math professional development. It competes for the same NSF and foundation grants as TDG and offers K-12 math PD at scale.

Direct peers

• Math Solutions: Math Solutions provides on-site professional development, coaching, and seminars for K-12 math educators, often delivered by former classroom teachers. It is a direct competitor in the math PD services space with a similar custom-engagement model.
• Carnegie Learning: Carnegie Learning combines MATHia software with embedded professional development and coaching for math teachers. It competes with TDG for district PD dollars and bundles services with curriculum, giving it stronger commercial leverage.
• CPM Educational Program: CPM provides K-12 math curriculum plus teacher professional development and coaching, including on-site workshops. Its focus on collaborative learning and teacher capacity building is comparable to TDG's Math Teaching Studios model.
• Illustrative Mathematics: Illustrative Mathematics develops open-source K-12 math curriculum paired with teacher professional learning, lesson study resources, and certification programs. It overlaps with TDG in math content, equity-oriented pedagogy, and teacher PD delivery.

Emerging players

• Student Achievement Partners: Student Achievement Partners supports implementation of college- and career-ready standards in math and ELA, with tools, professional learning, and classroom resources. It is comparable in its standards-aligned math teacher support mission, though broader in subject coverage.
• Math for America: Math for America is a nonprofit that builds communities of K-12 math teachers through fellowships, coaching, and professional development. It overlaps with TDG's mission of elevating math teaching and uses similar teacher-network and equity frames.
• TeachingWorks: TeachingWorks (housed at University of Michigan) works on the practice of teaching, including elementary mathematics, and is led by TDG board member Deborah Ball. It is a peer in the high-pedagogical-content math teacher development space and shares research-practice orientation.

Others

• National Council of Teachers of Mathematics (NCTM): NCTM is the national professional association for math educators, publishing standards, journals, and conferences. It is not a direct PD vendor but sets the agenda and network through which TDG's specialists and board members operate.
