In this study, we aimed to discover the meanings of parental involvement and the factors influencing parental involvement in high school, in Turkey. We conducted the study with 12 participants and applied phenomenological research design. After collecting the data with a semi-structured interview form, we applied descriptive analysis to it. The results of the study show that parental involvement carries multiple meanings that can be classified as home-based and school-based involvement. Several parent-family, child, school, teacher, and social factors influence parental involvement in high school. The practitioners should be aware of the plural meanings of parental involvement and run practices beyond the one-size-fits-all approach and enact policies to handle the possible barriers.
