Findings revealed that all two principals’ innovative practices (teamwork and delegation of responsibilities) had a significant positive correlation with instructional effectiveness. The paper suggested that principals should institutionalise teamwork practices, such as peer mentoring and team teaching, to promote knowledge sharing and innovation, and set a transparent expectations, outline specific roles, and implement feedback mechanisms to ensure tasks are understood and monitored.
