School culture significantly affects teacher retention rates by influencing job satisfaction and professional development. A positive school culture fosters collaboration and support among staff, which enhances teachers' sense of belonging and commitment. Conversely, a negative culture characterized by low morale and lack of support can lead to increased turnover rates. Factors such as administration support, recognition of achievements, opportunities for growth, and a shared vision contribute to the overall culture. Schools that prioritize a positive work environment are more likely to retain talented educators, ultimately benefiting student outcomes.
