This is awesome! While working as a student-teacher in a public school in India, correctly incentivizing students to attend school daily was a hard thing to do. Free lunch went a long way, but still fell short of getting an average of 50% attendance from the students because their parents often chose to engage them on their busy days as helping hands (not really sure how much help they were as an 8-yr old!). Rewarding school education with direct transfer after attendance is a great way of going about this.
I've made my first donation :). Good luck!!
