Inexperience is an asset. Embrace it.

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.

The evidence would suggest that there are some great alternative certification programmes and some lousy ones. There are some wonderful traditional education schools, and some that aren't so effective. What's important is less the pathway than the impact on students.

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.

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 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.

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.
