## CHAPTER 1: Introduction to the Teaching Pyramid Infant–Toddler Observation Scale

The Teaching Pyramid Infant–Toddler Observation Scale (TPITOS) is an assessment instrument designed to measure the fidelity of implementation of practices associated with the Pyramid Model in center-based infant and toddler care settings. The TPITOS provides a classroom snapshot of the adult behaviors and classroom-environment variables associated with supporting and promoting the social-emotional development of infants and toddlers. The Pyramid Model includes universal, secondary, and tertiary teaching practices.

### THE IMPORTANCE OF SOCIAL-EMOTIONAL DEVELOPMENT
In the United States today, growing numbers of children are attending quality pre-kindergarten programs, which greatly enhances children’s likelihood of success when they enter primary school. Unfortunately, thousands of preschoolers are suspended or expelled from preschool each year and miss the opportunity to benefit from preschool.

### ORGANIZATION OF THE TPITOS
The TPITOS Scoring Form includes three types of items: Observational Items, Interview Items, and Red Flags. Each Item includes two to nine Indicators that describe a specific aspect of teacher behavior. Observers score each Indicator based on their observation of the teacher demonstrating the practice during the 2-hour observation or from the teacher’s interview responses.

### ADMINISTRATION OF THE TPITOS
An observer carrying out a TPITOS observation will follow and record the behavior of one specific teacher on the practice items within four different routines for a 2-hour period: free play, structured group activity, care routines, and outdoor activities.

## POTENTIAL USES OF THE TPITOS
The TPITOS data may be used to identify and make explicit the specific competencies that promote social-emotional development and to monitor growth relevant to teacher competencies or quality-improvement initiatives. The TPITOS can also be used in research studies to measure implementation fidelity and change over time.

## RESEARCH BACKGROUND OF THE TPITOS
The first few years of a child’s life are a critical time. Approximately 10%–15% of children between birth and 5 years of age experience social-emotional difficulties that negatively affect their functioning and school readiness. Interventions focused on children’s early caregiving interactions can alleviate or reverse adverse effects of poverty on children’s social-emotional development.
