CHICAGO (AP) – The state of Illinois will distribute $87.5 million to hundreds of school districts that were underpaid because of a “coding error” — while seeking repayment from Chicago Public Schools, which mistakenly got the funds.

The appropriation is part of the $46.5 billion spending plan lawmakers passed Saturday.

The Illinois State Board of Education (ISBE) said a contractor made a “coding error” in the spring of 2018 during the initial implementation of a new state school funding formula.

As a result, 14 school systems are owed between $1 million and $5 million, while 565 are due up to $100,000 according to ISBE.

In total, 762 school systems were underpaid over the past four years.

Meanwhile, the state is trying to recoup the $87 million it mistakenly paid CPS, its largest school district.

ISBE said 52 other school systems were overpaid by a total of $3,396 during the affected period, and it will try to recover funds from districts that received at least $10 more than they should have.
