Role of Educational Administrative Support in Strengthening Teachers' Professional Development Trends and Classroom Instructional Performance

Abstract. Effective school leadership and administrative support play a key role in teacher growth and instructional quality. With ongoing educational reforms, it is important to understand how administrative practices influence teacher participation in professional development and classroom performance. This study examined the relationships among school administrative support, teacher engagement in professional development, and instructional performance. Specifically, it tested whether leadership practices, resource provision, and policy implementation relate to how often teachers join professional development activities and how effective their instruction is. A descriptive-correlational design was used. Data were collected from 83 public school teachers through a validated questionnaire and analyzed using weighted mean, standard deviation, and Spearman’s rho. Results showed that teachers reported very high levels of administrative support (M = 4.44), participation in professional development (M = 4.49), and instructional performance (M = 4.64). Correlation analysis revealed that administrative support had a significant positive relationship with both professional development participation (ρ = .517, p < .001) and instructional performance (ρ = .468, p < .001). This suggests that when school leaders provide consistent support, teachers are more likely to engage in development activities and deliver stronger instruction. The findings affirm that robust administrative support systems are essential for sustaining teacher development and high instructional standards. School leaders should maintain effective leadership practices, ensure adequate resources, and uphold supportive policies that promote continuous learning. Because the observed relationships are stable, preserving current practices can help maintain these high outcomes in similar school contexts. The study provides practical implications for administrators who aim to improve school effectiveness through targeted leadership and support. Future research may explore these relationships in other divisions and include additional variables such as teacher motivation and school climate.
