These scales are designed to measure the nature of educators' interactions with children as this is key to the quality of the early learning experience:

• Classroom Assessment Scoring System (CLASS) - a system for observing and assessing the quality of interactions between ECEs and teachers and their students.
• Caregiver Interaction Scale (CIS) - a reliable measure of the interactions
  between child care providers and the children they care for in both centre‐based and home child care settings.
