This doctoral dissertation explored communication between school principals and teachers and how those types of communication impact school culture. The information also investigated how much teachers communicate with each other. Communication breakdown has become one of the issues most affecting organizations, which has caused slow improvement among institutions (Bucata & Rizescu, 2017). This study aimed at gaining an in-depth understanding of how communication is handled in various schools and how school principals achieve schools' objectives through communication with teachers. Furthermore, in-depth interviews as opposed to short-answer quantitative questions were used in this qualitative study. The adopted study design, a qualitative approach, guaranteed efficiency in data collection and analysis. For this reason, the design enhanced the research validity and reliability, prompting primary stakeholders in the educational setting to adopt and implement suggested recommendations. A qualitative case study was used to provide clear answers to the study as well as a better understanding of the participants' perceptions, feelings, experiences, recommendations, and thoughts. A case study suited this research because of the need to explore the similarities and differences in the educational environment.
