Infant Toddler Temperament Tool (IT3)

The Infant Toddler Temperament Tool (IT3) was developed for the Center for Early Childhood Mental Health Consultation, an Innovation and Support Project funded by the Office of Head Start.

I am completing the IT3 for myself and (child's name) 

Directions for completing the IT3 for you and the infant:

Please rate yourself and the infant on the following 9 traits. Check the box for each trait that comes closest to describing each of your regular behaviors. Remember, you can use the chart of Temperament Traits for definitions of each trait.

While individuals' temperaments fall along a continuum, choose the typical behavior that describes how you and the infant regularly behave.

There are no “good” or “bad” temperamental traits; every infant is born with unique personalities that make them special.

The IT3 takes approximately 5-10 minutes to complete.

Read the following statement as you rate each trait for you and the infant. More often than not, you and the infant behave in a way that can be described as:
