One of the unfortunate consequences of the COVID-19 pandemic is that the sharp downturn in tax revenues, in the absence of a federal bailout, likely foretells unprecedented cuts in state and local budgets. This will in turn mean large cuts in teaching positions across the country; indeed, some projections suggest that the number of teacher layoffs in public schools could be in the hundreds of thousands.
There is little doubt that this will have significant impacts on students. But we’ve also learned some lessons from the Great Recession, the last time that layoffs (and the threat of layoffs) were a prominent feature of the education landscape. These lessons won’t allow policymakers to eliminate the educational harm associated with layoffs, but they do suggest concrete ways to mitigate the harm to students associated with painful cuts to educational budgets. Below we describe some of the research on the effects of teacher layoffs, and what it suggests about impacts on students.
Research on teacher layoffs (and potential layoffs) during the Great Recession quite definitively shows that considering teacher performance when making layoff decisions is important if the paramount issue is minimizing the harm to student achievement. At the time, layoff decisions in most districts and states were largely determined by teacher seniority, because of either state laws or provisions in collective bargaining agreements (CBAs). On the face of it, this makes some sense, not only because teachers tend to view this system as equitable and valid, but also because there is good evidence that teachers tend to improve their performance or effectiveness as they gain experience.
However, teaching experience is not determinative of performance; for example, many first-year teachers are more effective than the average experienced teacher, and vice versa. Thus, it’s not rocket science to conclude that a layoff system that relies only on seniority will necessitate letting go of many effective teachers. This is borne out by research:
The above literature paints a pretty clear picture of the student achievement impacts of relying exclusively on seniority for making layoff decisions. But there are several other important considerations to take into account when determining the layoff process:
Decisions about how to deal with an unfortunate need to reduce teaching positions are challenging. Using a seniority-based approach to determine which teachers receive pink slips has some advantages in terms of transparency and administrative ease. But the existing empirical research is quite clear that this is not the best approach for mitigating the harmful effects of layoffs on student achievement. And while we cannot say with any precision how layoffs would be distributed in specific school systems (as the distribution of teacher seniority can differ substantially by context), the evidence on the distribution of teachers across schools and students strongly suggests that layoffs based on seniority alone will tend to fall mostly heavily on higher-poverty students and students of color. These are the very students that many observers believe will be most harmed by the pandemic. All of this suggests the importance of careful consideration about the consequences to students of the processes that are used to determine layoffs.
 The 2019–20 version of the California Teachers Association Organizational Handbook states, “The seniority system should be encouraged. The seniority system has demonstrated its equity and validity in protecting the rights of all employees. All personnel begin vesting in the system from the first day of service, and modification of the seniority system imperils job security for all employees” (p. 243).
 “Performance” generally refers to a formalized evaluation rating, whereas “effectiveness” implies the estimated impact of teachers on student test achievement. Henceforth we use “performance” to encompass both, except in describing the findings from specific research studies, where we distinguish between the two.
 Our more recent research has shown that the policy landscape around layoffs in Washington is largely unchanged since the Great Recession; over 90% of district CBAs in the state still specify seniority as the primary factor in determining the order of layoff notices. But there has been a much larger shift across the largest districts in the country, as tracked by the National Council on Teacher Quality’s (NCTQ’s) TR3 database. In fact, as reported by NCTQ, more of these large districts now use performance as the primary factor in layoff notices than use seniority.
 A second distributional concern is related to the subject areas of teachers who are laid off. A prime example is special education; districts tend to have a more difficult time staffing special education classrooms, largely because attrition rates from these classrooms tend to be higher than from other classrooms, and as a result there tend to be more novice special education teachers than in other fields.
