Year-round school is the organization of days within a school calendar year to provide students with regular breaks and instructional blocks. This study surveyed 502 parents to identify factors influencing parental support for, or opposition to, year-round school. Three themes were constructed based on parent responses: children need educational enrichment in the summer, summertime provides essential opportunities for personal restoration, and summertime strengthens family relationships. The study findings illustrated the complexity of factors influencing parental perceptions of year-round school; parents both for and against year-round school identified similar factors, yet for different reasons. Implications and limitations are explored.
