TMW Center: By the Numbers

At the TMW Center, our work is fueled by the belief that science is the basis for real social change, and it leads to thousands more parents and caregivers in this country having access to information and tools that help them optimize the foundational brain development of their children. See below for a quantitative look at our work and our impact over the years.


  • 3Ts at the heart of all TMW Center programs and interventions. These easy-to-apply, evidence-based strategies remind parents to “Tune In and respond to what your child is communicating; Talk More and build your child’s vocabulary with descriptive language; and Take Turns to engage your child in conversation and foster curiosity and knowledge”
  • 3 languages (English, Spanish, and Haitian Creole) in which TMW Center materials are available
  • 5 books written or edited by our Center Co-Directors Dr. Dana Suskind & John List
  • 8 evidence-based interventions developed for parents & caregivers, each designed to be embedded within existing systems and tailored to a specific setting and phase of life
  • 8 communities with sites that implement TMW Center programs (Akron, Chicago, Dallas, Houston, Lexington, Palm Beach, Phoenix, St. Louis)
  • 11 years since Dr. Dana Suskind launched the precursor to our Center, the Thirty Million Words Initiative, in 2010
  • 12 randomized control, quasi-experimental and implementation trials of TMW Center interventions completed, with results indicating that these interventions lead to an increase in parent and caregiver knowledge of brain development and richer early language environments for children
