The document presents the Teaching Pyramid Infant-Toddler Observation Scale (TPITOS), a tool designed to measure and enhance social and emotional competence in infant and toddler classrooms. TPITOS allows for classroom observations and feedback on adult behaviors, helping to guide professional development and coaching efforts in early childhood settings. It provides structured indicators and scoring criteria to evaluate teaching practices and supports the implementation of the Pyramid Model across various practices in infant-toddler environments.
