Study Details
Setting
The study takes place in 10 public elementary schools with 26 pre-K classes in two disadvantaged urban school districts in New York City.
Study sample
The student sample includes kindergarten students (who were in pre-K at the start of the intervention) at 10 public schools in New York City. Study schools were located within two districts in disadvantaged New York City neighborhoods. The districts had less than half of their students graduate from high school and had more than two thirds of students eligible for free lunch. Almost half of the students in the elementary schools in the districts were performing below grade level in reading and math.
Intervention Group
ParentCorps has two main components. First, parents of pre-K students participate in a series of 13 2-hour after school group classes led by a pre-K teacher. Second, pre-K and kindergarten teachers receive additional professional development support, consisting of 7 days of classes over 2 years and 6 hours per year of consultation. Through these two components, the program aims to increase positive behavior support, behavior management, and parent involvement in education.
Comparison Group
Pre-k and Kindergarten programming as usual (according to New York City Department of Education guidelines) was provided in the control schools.
Support for implementation
All intervention procedures were described in manuals. Teachers who led the children group sessions were provided additional training.
