Evidence Based Funding Model (EBM)

During the 2017 legislative session, the Illinois General Assembly passed a new funding formula for school districts in the state of Illinois, called the Evidence-Based Funding model. Based on the concept of adequacy, the model uses research as well as cost calculations by locale to determine what the adequate number of dollars flowing to each district should be. It is a fairly complicated formula, with at least 26 markers to be considered. 

As of the last posting, the Illinois State Board of Education has asked for $7.2 billion more from the legislature to reach the adequacy funding marks noted in the formula. In the 2017 legislative session, the legislature appropriated $300,000,000 more than in 2016 to address funding concerns raised in the EBM, but ISBE has clearly noted this is not nearly enough.

At some level, whether schools are funded adequately becomes a political battle over taxes and allocation of dollars. However, now that the legislature has passed the EBM, the ISBE is calling on the legislature to fund their own formula. How this will play out over the next few years is unknown, and should make for a sometimes entertaining, sometimes frustrating state of play in Springfield as the EBM and issues surrounding the state budget continue.

Here are a few documents which can be used to better understand the concepts in the EBM formula. They are not provided by ISBE, and therefore may not be 100% accurate to what is finally produced by ISBE, when that time comes. It will, however, give the studied reader a better grasp of what the formula aims to do. 

A caution when reading these documents: the number of teachers per grade level is from research across many school districts in several states. As with any average, not everything fits each and every district. These documents do not create a required staffing level in any area, but only uses the averages to determine funding for each district. How dollars are used from there is at the discretion of each school district, at least for now.





Again, please note these are for the purposes of understanding the EBM and may or may not exactly represent ISBEs final EBM and rules which accompany their EBM.
