Moody’s Investors Service has assigned Cobb County schools its Triple A rating — the highest credit rating available for a government entity and the first time in Cobb’s history it has earned the rating.

The Triple A rating "reflects the district's sizable and diverse tax base, sound reserve position characterized by conservative budgeting and formal financial policies, and an above average pension burden, mitigated by the absence of any long-term debt," according to a released statement from the Cobb school district.

Credit ratings represent the credit worthiness of corporations and government bodies. Ratings help determine borrowing costs and the amount of interest paid on debt.

The Cobb district is the second-largest school system in Georgia, with close to 113,000 students.
