The Parent Leadership Institute (PLI) of Children's Aid (CA), funded via a 2013 Investing in Innovation (i3) development grant operated between the 2014-15 through 2018-19 school years. Key goals of the PLI included: (1) improving the capacity of parents to effectively engage in the school community in support of their child; and (2) increasing the capacity of school staff to create and support environments which are welcoming to and supportive of the active engagement of parents as key members of the school community. Through implementation of the PLI, CA expanded its partnership with six schools located in the South Bronx community of Morrisania, an area characterized by high levels of poverty, health disparities, and crime, and low levels of academic achievement and attainment among both children and adults. This report serves as the final report on this phase of the PLI and includes an exploration of implementation during year 4 (2016-17 school year) and analyses of quantitative data on student academic performance.
