This qualitative cross-case study aimed to explore effective communication in suburban and urban schools. The study investigated K-12 leaders' perceptions of effective communication with parents in suburban and urban school districts. Three open-ended questions guided the research: 1) What are principals' perceptions of effective communication with parents?, 2) What are principals' perceptions of effective strategies of school-home communication?, and 3) What are the barriers that may obstruct effective communication between principals and families? This cross-case study is unique as it focused on school leaders' perspectives to define effective communication. Strategies, methods, and barriers were identified by participant school leaders. The findings of this study resulted in four primary themes: the definition of effective communication, strategies of effective communication, methods and ways of effective communication, and barriers to effective communication. These themes provide valuable insights that can be applied to professional practice by K-12 school leaders.
