The limitations of federal laws are able to create real progress at the local level. Ultimately, to effect not just incremental progress but progress that is transformational for students, we need committed leadership - people who believe deeply that their students can achieve at the highest levels and who know how to create the conditions at the classroom, school and system level to give them the opportunities they deserve.

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 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.

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.

When school district officials literally laughed at the notion that the Me Generation — this was the label for my generation — would jump at the chance to teach in urban and rural communities, their concerns, too, went unheard. My very greatest asset was that I simply did not understand what was impossible.

People are attracted to teaching because they want to make a real impact. The teachers who are making the greatest difference go far beyond meeting standardised test measures. They aspire to truly level the playing field for their students, which means inspiring a love of learning, fostering the highest levels of critical thinking, building perseverance in working towards academic excellence, and so on.

Standardised tests cannot capture all, but on the other hand, students who are not capable of doing well on standardised tests are not well-equipped to thrive in today's world and so it's important for teachers to ensure that students gain the foundation necessary to meet the baseline educational standards these tests represent.
