This research brief is Part 4 of a four-part study of decentralization in Houston Independent School District (ISD). This part examines the impact of decentralization on funding equity. It looks at the general fund budgeting strategy in Houston ISD from 1999-2000 through 2015-16 to see how much money schools got and use human resource data from 2013-14 through 2015-16 to see how they were using it. The study found that: (1) Middle schools and high schools had larger total general fund budgets and more per student spending than elementary schools; (2) Small schools had higher per student spending than non-small schools, even though their total general fund budgets were not different; (3) Schools with a higher proportion of economically disadvantaged students had larger total general fund budgets, while having slightly lower per student spending; and (4) Enrollment size was the best predictor of key personnel at a school, with larger schools being more likely to have assistant principals, counselors, nurses, and librarians.
