Evidence. Kindergarten 24% lower risk reading below grade level
Evidence. Elementary School 50% fewer mental health problems




Strong evidence of ParentCorps’ impact on children, families and teachers comes from two randomized controlled trials with more than 1,200 Black and brown children in low-income neighborhoods in NYC.

ParentCorps' full model has meaningful and sustained impacts on children's academic achievement, mental health and physical health, one of very few early childhood programs with demonstrated impact on all three critical areas of development. In elementary school, children showed a 24% lower risk of reading below grade level; were 50% less likely to develop mental health problems; and were 50% less likely to be obese, through second grade. In middle school, children were 44% less likely to be chronically absent (e.g. more than 10% of days in the school year), through sixth grade. 

In addition, ParentCorps has meaningful impacts on parenting and teacher practices, strengthening teachers and parents' capacities to create safe, nurturing and predictable environments both in the classroom and at home. Parents showed greater involvement in their children’s learning, increased parenting knowledge, and increased use of evidence-based practices (such as positive reinforcement), while teachers demonstrated more nurturing teacher-student interactions and effective behavior management in the classroom.  

In a cost-effectiveness analysis, ParentCorps was found to have a 4:1 return on investment over and above the well-documented benefits of pre-K.

“Anyone who knows anything about early childhood education
and health and development is familiar with the pioneering research
that Dr. Brotman has led and the ParentCorps program...
This will be a game-changer for many of our students here in New York City."

Richard Carranza, New York City Department of Education Chancellor (2018-2021)
