The purpose of this quantitative study was to examine the opinions and views of teachers on parental involvement in elementary and high school education in the United States. This study utilizes secondary data acquired from the RAND American Teacher Panel (ATP), which is a nationally representative sample of K-12 school teachers. The specific study sample consisted of 10,529 teachers from RAND ATP across 22 states in the United States and was designed to sufficiently facilitate national analyses. The May 2017 Measurement Learning and Improvement (MLI) survey was the instrument of application and was administered online. Over 20,900 invitation emails were sent out. The findings of the study indicate that the percentage of white students, the percentage of students in the free or reduced-price lunch program, the size of the school, and the urbanicity of the school are predictors of both home-school communication and parental involvement. The study is significant for all educators and especially for principals seeking to understand and improve parental involvement in their schools.
