"The most successful teachers in low-income communities operate like successful leaders. They establish a vision of where their students will be performing at the end of the year that many believe to be unrealistic. They invest their students in working harder than they ever have to reach that vision, maximise their classroom time in a goal-oriented manner through purposeful planning and effective execution, reflect constantly on their progress to improve their performance over time, and do whatever it takes to overcome the many challenges they face."
