Using Data to Better Understand the Educator Workforce

The Illinois State Board of Education (ISBE) has been sharing a snapshot of the supply, demand, and educator shortages in Illinois for roughly twenty years. This past December, they released their latest version of the triennial Educator and Supply Report, featuring an ambitious and expanded scope. The report analyzes a wide set of metrics, using employment data from teachers, administrators, and support staff. 

There’s a great deal to dig into. For my part, having released a report this past fall on how the state has been doing in growing, preparing and retaining its educator workforce, especially amidst COVID, I found certain data points of particular interest. This included updated educator retention data from SY22-23, which suggest that teacher and principal retention has largely returned to pre-pandemic levels after a temporary 'boost' during the early pandemic years (though what these trends look like can depend on how you define ‘retention’). Interestingly, ISBE’s analysis also shows that the number of former educators returning to the profession, which decreased in the first year of the pandemic, still hasn’t bounced back. 

While these overall numbers are important, anyone who lives in Illinois knows that there are significant differences in educator supply and demand across communities and schools throughout the state. The most recent report embraces this geographic diversity, demonstrating how retention varies from region to region. 

There are real regional disparities across certain metrics. Yet ISBE’s analysis also makes clear that some challenges are consistent across the state. While the racial composition of public school students varies from place to place, every region in the state sees a profound gap between the percentage of students of color and percentage of teachers of color. It is both intuitive and substantially research-backed that a racially and ethnically diverse teacher workforce matters. Still, no matter where in Illinois you look, you’ll see a workforce that is far from representative of local students. 

Finally, the report reminds us that reality does not always reflect our expectations. For example, we know that there is high demand for bilingual and foreign language teachers. That said, data from the last three years show that rates at which completers of educator preparation programs were hired into Illinois public schools within one year of completion were lower for educators with bilingual and foreign language endorsements compared to educators endorsed in most other areas. 

To me, this exemplifies why reports—and data—like this matter; our assumptions about trends and challenges may not align with reality. On its own, data cannot fix what ails Illinois’ educator workforce. But it’s a critical tool for understanding where the real challenges actually are, how they manifest, and what it will take to address them. If we don’t accurately understand the problem, we may propose or invest in misguided solutions. ISBE’s report, in combination with other recent or upcoming research and analyses, is not only illuminating and important, but should help guide efforts to build out and support the educator workforce this coming legislative session and beyond.
