Creating a high-functioning education system requires all the strategies involved in building high-functioning organisations anywhere. It requires a deliberate and aggressive strategy to ensure extraordinary talent at every level of the system, from the superintendentcy to district offices to principalships to classrooms. It requires building systems for accountability; offering parents the ability to choose their public schools is the ultimate form of this. It requires building a strong culture at the system and school levels based on high expectations for student achievement.

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.

I often hear from new graduates that it's better to wait until you have more experience.... But I'm a big believer in the power of inexperience.... The world needs you before you stop asking naive questions and while you have the time to understand the true nature of the complex problems we face and take them on.

The most reliable way to be certain of their classroom impact is through independent studies conducted by third-party organisations which compare the student growth in our corps members' classrooms to that of other teachers in similar situations.

Education is the most powerful tool countries have for boosting economic growth, increasing prosperity and forging more just, peaceful and equitable societies. Where educational deprivation exists, it breeds conflict and enables repression.

I have not seen that standardised tests make the profession less attractive, though some principals respond to them in a way that drives the best teachers out of their schools (by over-emphasising test prep in the school curriculum for example). On the other hand, great teachers want benchmarks to measure progress and tests can help with that.

Inexperience is an asset. Embrace it.
