These leaders show just how much it will take to make a meaningful difference for the most-marginalized children. Success will require more than single interventions like giving children tablets, or providing teachers with better curriculums -- these steps may be part of the solution, but they are just one piece of what must be a holistic approach.
If the world is to have a chance of achieving this ambitious education goal, we know that domestic and donor funding needs to be in place; that it is state systems -- not private systems -- which ensure equitable access to quality education; that there is no quality education without trained teachers; and that targeted interventions to support the most disadvantaged across our societies are vital to ensure no-one is left behind.
I had the idea that when I went to college, I would major in math. I did well another couple of years. However, in the 7th grade I had a dull older professor who perpetuated the "girls can't do math" myth. Once I had questions, it was decided that I couldn't "do math." I didn't "get it" immediately because I'm a girl. End of math career.
