The Hartford Board of Education is considering whether to grant another charter to the charter chain called Achievement First.

AF is a political powerhouse. Stefan Pryor, the state commissioner of education, was a co-founder.

AF is noted for high test scores but also for the highest suspension rates in the state. It has been criticized for its harsh disciplinary policies and its very low enrollment of English language learners and children with disabilities.

Another AF charter will skim off the best students and leave the majority of students in Hartford worse off.

But it will be very good for AF.
