How school funding problems affect students, taxpayers

Wealth-based inequities persist after first year of evidence-based funding

SPRINGFIELD — Education officials in Illinois say the state is making solid progress under its new evidence-based funding program in narrowing the wealth-based disparities among school districts, but an analysis of the first year of that program shows just how far the state still has to go.

During the 2017-2018 academic year, new data from the Illinois State Board of Education shows, school districts with large amounts of property wealth were better funded than their property-poor counterparts, enabling them to spend more money per-pupil. That in turn translated into higher student test scores in math and English language arts.

Meanwhile, residents of property-poor school districts generally paid higher property tax rates than people in wealthy districts, while their school districts continued to be underfunded and fewer students in those districts were able to meet state expectations on standardized tests.

Those are the conclusions of an analysis by Capitol News Illinois that examined financial information from 850 public school districts, combined with school performance data from the Illinois Report Card during the 2017-2018 academic year, the most recent year for which all data is available. 

“None of that surprises me,” state Sen. Andy Manar, D-Bunker Hill, said in an interview. “None of what the state board released is shocking to me because the compromise at the end was an incremental step.” He is the chief architect of the evidence-based funding system.

Evidence-Based Funding

State lawmakers adopted the evidence-based funding system in 2017.

The idea was to determine each school district’s “adequacy target” — the amount of money it needs to provide the educational services required by the state. That target is based on factors unique to each district, such as the district’s size, and the number of low-income students, English language learners and students with special education needs.

The 2017 law also calls for the state to increase school funding by at least $350 million each year, with districts furthest below their adequacy target getting first priority for new money. The stated goal is to bring all districts up to at least 90 percent of adequacy by 2027.

According to data released at ISBE’s June meeting, however, the increased annual investment in the formula would need to be closer to $660 million in order to bring all districts to 90 percent adequacy during that span.

According to ISBE, it would have cost the state an additional $7.4 billion in fiscal year 2018 to bring all districts up to at least 100 percent of adequacy. For the current fiscal year, that figure stands at $7.1 billion.

The evidence-based funding system went into effect in the 2017-2018 school year, and final numbers for that year from the Illinois State Board of Education were just released in August.

Those numbers show that total funding for 850 school districts — including local, state and federal funds — ranged from 47 percent of adequacy in the J.S. Morton High School District in Cook County to 288 percent of adequacy in the Rondout School District, an elementary district in Lake County.

All told, 652 districts received less than 90 percent of their adequacy target, including 144 that received less than 60 percent of their adequacy. The average across all districts was 79.5 percent of adequacy.

Bruce Baker, an education professor at Rutgers University in New Jersey who studies school finance systems, said Illinois for many years had one of the most inequitable funding systems in the country.

“I think Illinois is as big an outlier as it is, in part because the city of Chicago is such a large district with such concentrated poverty and has been poorly funded for decades now, and it’s a very expensive problem to fix,” Baker said in a phone interview. “It costs billions of dollars to dig the city of Chicago out of its hole, and that means within a statewide budget, finding that much money to target into one area of the state, which is always a very difficult political problem to solve.”

Wealth determines adequacy

Chicago Public Schools, with just over 372,000 students, is the third-largest school district in the nation, and in terms of property value, it’s a district of great wealth. In the 2017-2018 year, it reported just over $74 billion in taxable property value.

But the Chicago district also has a relatively low property tax rate, levying just 3.36 percent of equalized assessed value, far below the statewide average of 4.3 percent. Revenue from local taxes, at just under $3.5 billion, made up 56.3 percent of the district’s total revenue. The state of Illinois paid in just under $2 billion, or 31.9 percent.

Elsewhere in the state, however, property wealth was the single biggest determinant of how adequately funded a district is.

Taxable property value during the 2017-2018 year ranged from a low of $19,332.45 per-pupil in the DePue district to a high of more than $2.5 million per-pupil in the Rondout district. The average among the 850 districts was $252,070.55.

According to ISBE data, there was a clear correlation between property wealth and funding adequacy: Poorer districts tended to be the least adequately funded, while wealthier districts enjoyed the greatest funding.

During the 2017-2018 academic year, the data shows that, generally, a $10,000 increase in a district’s per-pupil taxable property value translated to a 0.9 percentage point increase in the district’s funding adequacy.

That is primarily due to local resources, largely property taxes, accounting for two-thirds of all education spending in Illinois.

“Student background is a big deal, and adequate funding providing smaller classes and more qualified teachers can offset some of that,” Rutgers University’s Baker said. “However, inadequate and inequitable funding will only serve to reinforce it. So you’ve got everything self-reinforcing here. You’ve got the neediest kids in the poorest districts with the least resources.”

The 2017-2018 data also shows that wealthier districts pay substantially lower property tax rates. In fact, many of the poorest districts in the state, in terms of property wealth, paid the highest property tax rates while the wealthiest districts paid the lowest tax rates.

The poor districts were led by the Ford Heights School District 169, in Cook County, which reported a per-pupil property value of just under $79,000, less than one-third the statewide average, where property owners paid a school tax rate of nearly 21 percent, nearly five times the state average.

At the other end of the spectrum was the wealthiest district on a per-pupil basis, Rondout, with per-pupil property value at more than $2.5 million and where residents paid a tax rate to the district of just 1.57 percent, the eighth-lowest rate of any school district in the state.
