The fact is Baltimore City charter schools receive about $9,300 per student, while Baltimore's traditional schools receive about $7,300 per student. In exchange for more cash, charters pay for or opt out of district services including professional development. Charters have fewer network staff supporting their work. Charter budgets also cover costs that traditional school budgets do not, including principal salaries and student transportation. Do the additional services that traditional schools receive make up the difference in their lower per pupil funding? In our experience the answer is no, but we want the facts.
