The five-year grant will be disbursed New Schools for New Orleans and the Charter School Growth Fund and is aimed at improving educational opportunities for 15,000 kids. It follows the Houston-based Arnold Foundation’s $15-million gift in September to 10 schools and education-reform organizations in New Orleans.
