Unless the private school has a majority of its student body classed as economically disadvantaged, I don't see getting credit for teaching financial education. Or are you thinking primarily parochial schools in the inner city?
Now there are plenty of charter schools established in LMI geographies and/or have a majority of students that are economically disadvantaged to get service credit for teaching financial education.
