This case study focused on middle school and high school teachers in an independent school to explore their perceptions of how overparenting influenced them in the classroom. A qualitative case study was conducted within an independent school in the southeast United States. Eleven middle school and high school teachers, which represented 52% of the full-time faculty at the school, participated in an online questionnaire and follow-up interviews regarding their experiences with overparenting. Findings revealed three themes: (a) teachers overwhelmingly associated parent--teacher interactions with conflict and confrontation, (b) teachers perceived overparenting influences teacher autonomy by forcing teachers to set boundaries, and (c) teachers experienced increased workloads. This study provides insight into how overparenting influences teachers, which may help teachers, administrators, and future educators prepare for this type of parent--teacher interaction.
