“The effect of homelessness on a child’s schooling can be devastating. Nearly 40 percent of homeless students missed at least a month of school during the 2014-15 school year, according to the Institute for Children, Poverty and Homelessness. And even students in stable housing who have been homeless in the past tend to perform far worse than their peers. The Institute found that the math-proficiency rate for third through eighth graders was just 21 percent among formerly homeless students, 13 percentage points behind other children who are poor, but have always had a place to live.”
