What if you could triple the speed of student learning? According to findings by Professor John Hattie, a strong sense of Collective Teacher Efficacy can yield over three years of student growth over one school year. Now ranked the most powerful influence on achievement in the Visible Learning research, Collective Teacher Efficacy is a belief that together teachers can positively impact student learning.
