This report presents data on students in the United States attending kindergarten through grade 12. The main focus of the report is on parent and family involvement in the students' education during the 2011-12 school year as reported by the students' parents. It also includes the percentage of students who participated in selected family activities. Demographic information about students and families is presented, including students' poverty status and parents' education and language spoken at home, as well as school characteristics, such as school size and school type. The data for this report come from the National Household Education Surveys Program of 2012 (NHES:2012), Parent and Family Involvement in Education (PFI) Survey. The PFI survey is designed for students who are enrolled in kindergarten through grade 12 or are homeschooled for equivalent grades and asks questions about various aspects of parent involvement in education, such as help with homework, family activities, and parent involvement at school. For homeschooled students, the survey asks questions related to the student's homeschooling experiences, the sources of the curriculum, and the reasons for homeschooling. This report (NCES 2013-028.REV2) is revised from an earlier version (NCES 2013-028.REV) that was released in May 2015. This updated version corrects an error in the standard error estimates presented in table C-1. The correction was made to the standard errors reported for the estimated total number of students in kindergarten through grade 12 by school, student, and family characteristics. All other estimates and findings presented in the report remain unchanged.
