School districts are evaluated by ratings agencies to determine creditworthiness. Humble ISD in 2021 received an AA bond rating from Standard & Poor’s (S&P) and an Aa1 rating from Moody’s Investors Service in 2021. This bond rating is equal to or higher than 98 percent of Texas public school districts.

“The Aa1 issuer rating reflects the district's growing economy in the Houston metropolitan area, with favorable resident income indices and a growing enrollment base even during the ongoing pandemic. The district's stable finances have resulted in the build-up of healthy liquidity and reserves," Moody's news release stated. "The stable outlook reflects our expectation that the district will continue to exhibit sound financial management and maintain healthy general reserves.”
