Collective teacher efficacy significantly influences student academic performance through shared goals and beliefs among educators. When teachers work collaboratively, they develop a unified approach to teaching, enhancing instructional quality. Their belief in their collective capability fosters a positive learning environment where students feel supported. Research shows that schools with high collective efficacy often achieve better student outcomes, as teachers share strategies and insights that benefit all learners. This collaborative effort strengthens pedagogy and addresses diverse learning needs, ultimately contributing to improved academic results and creating an environment that prioritizes student growth and achievement.
