What types of subject-area teacher shortages do states experience? Are there major trends across states in chronic subject-area teacher shortages? How different are subject-area teacher shortages between states?
These were some of the questions my colleague Justin Trinidad and I sought to answer in our new report “Nuance in the Noise: The Complex Reality of Teacher Shortages.” We dove into a national data set on teacher shortage areas submitted by states and territories to the U.S. Department of Education. This data set is one of the best sources we have to analyze trends in subject-area shortages across the country and for each particular state.
Given this fact, were were shocked by just how messy the data were. We quickly found that there is no standard reporting framework that states must use. This means each state defines their own subject areas as they see fit. For example, Colorado reports its science shortages under the multiple categories of “Science,” “Natural Science, “Natural Sciences (Grades 7-12),” and “Natural Sciences (Kindergarten-Grade 12),” while Georgia uses the categories of “Sciences,” “Sciences (K-Grade 6),” and “Sciences – Secondary.”
This lack of standardization meant we had to create our own methodology in order to analyze the data, and even then, cross-state comparisons were difficult! That was annoying and a ton of work, yes, but it also spoke to a larger trend we see in teacher supply and demand data: they are hard to understand and often tell an incomplete story. What states report to the feds is often not the same thing they list on their state education websites.
However, frustrations with data didn’t stop us from finding some interesting and important information in our analysis. In fact, what we found challenges a widely held belief: that there is a generic, national teacher shortage. It turns out that teacher shortage needs vary widely across states. States even have varying experiences with the more chronic shortage areas like mathematics.
As the below map shows, California reported mathematics shortages less than 20 percent of the time of our analysis, while four states — Louisiana, Maine, North Carolina, and Texas — reported mathematics shortages all 20 years of our analysis.
