Classroom Ratios + Conversational Turns 

Teacher-child ratios — the number of teachers vs. children in a classroom — are a major factor in classroom quality. Lower ratios allow educators to provide more individualized supports, safer settings, and efficient classroom management. In this report, we examine the role teacher-child ratios may play in the number of conversational turns children experience in early learning classrooms.
