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.

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.

As a country [USA], we can attract more talented people to teaching by raising awareness of educational inequity and getting the public to understand from individual classrooms, schools, and cities that this is an issue that can be solved.

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.

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.

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.
