CHICAGO (S&P Global Ratings) Jan. 14, 2021--S&P Global Ratings revised its outlook on Cook County School District No. 88 (Bellwood), Ill.'s general obligation (GO) debt to positive from stable. At the same time, we affirmed our 'A-' long-term rating on the GO debt. We also assigned our 'A-' rating, with a positive outlook, to the district's $5.7 million series 2021A GO limited-tax school bonds and $18.9 million series 2021B taxable GO limited-tax bonds. "We revised the outlook because the district's new management has dramatically improved its budgetary performance with the help of a favorable change in state funding, resulting in a recent history of positive operations and growth in available reserves to a strong level," said S&P Global Ratings credit
