Among the challenges complicating Mississippi’s progress toward achieving its long-term education goals may be an unusually high rate of teacher turnover in the very subjects for which it conducts standardized assessments. Results from the 2022 Mississippi Teacher Survey demonstrate that teachers in state-tested subject areas are significantly more likely to report plans to leave their teaching position by the end of the school year than their colleagues in non-state-tested subjects.

To be sure, Mississippi has enjoyed some good news on the state testing front recently: results from the 2021-2022 school year indicate that teachers and their students overcame two years of pandemic-related challenges to report scores comparable to pre-pandemic levels. This is undoubtedly a testament to the resilience and determination of everyone involved. But as Mississippi looks to move past the pandemic and toward its long-term goals—in particular its goal for 70% of students to reach proficiency in ELA and math by 2025—it is worth examining what barriers remain to further progress. 

One obvious barrier is Mississippi’s ongoing teacher shortage. Statewide, 104 out of 148 school districts are classified as “critical shortage areas” due to their challenges in hiring teachers in any subject. However, teachers in state-tested areas are in charge of delivering instruction in some of the most foundational subjects—math, ELA, science, and history—and the progress of their students plays an outsize role in metrics used by the Mississippi Statewide Accountability System. Unusually high attrition risk in these areas threatens progress at all levels, from individual student growth to meeting statewide proficiency goals. What explains the higher attrition risk for teachers in state-tested subjects, and what does it mean for Mississippi students?

Insights from the 2022 Mississippi Teacher Survey

In November 2021, we surveyed 6,496 teachers across Mississippi to better understand teachers’ experiences and perspectives on the educator pipeline. Among other analyses (to be released in a forthcoming report), the resulting data allows us to examine differences in attrition risk between state-tested and non-state-tested teachers. For the purposes of this post, we chose to focus our analyses on teachers in grades 3-8, narrowing our sample to 3,220 respondents. The group of state-tested teachers includes those who teach 3rd-8th grade math or ELA, 5th grade science, or 8th grade science. The group of non-state-tested teachers includes those who teach any other subject in grades 3-8. 

To measure attrition risk, we looked at the proportion of teachers in each group whose survey responses indicate that they are “somewhat likely” or “very likely” to exit their classroom position (as of November 2021) within the next year to teach in another state, obtain a different role in education, or exit the education field entirely. We refer to these individuals as “likely leavers.” We measure a group’s attrition risk by determining its percentage of likely leavers. 

We find that the attrition risk of state-tested teachers is almost 6 percentage points higher than the attrition risk of their peers: 58.9% of teachers in state-tested subjects are likely leavers, compared to 53.1% of teachers in non-state-tested subjects. The difference in these rates is statistically significant, meaning that it cannot be attributed to chance.

We have observed elsewhere in our survey data that attrition risk is related to the length of one’s teaching experience: there appears to be an increase in attrition risk in the early stages of a teacher’s career, followed by a decrease in the middle stages of their career that continues until they reach retirement age. Considering this trend, we were interested to see how attrition risk varies between state-tested and non-state-tested teachers within different career stages. As the graph below demonstrates, attrition risk appears to be higher among teachers in state-tested subjects across all levels of experience; however, these differences are only statistically significant for teachers with 0-5 years of experience, and for teachers with 18-23 years of experience.

This finding leads us to predict teachers are most likely to teach in state-tested subjects in the first years of their career and least likely in the last years of their career. Our data appear to verify this pattern. The graph below demonstrates that the group of early career teachers (0-5 years of experience) has the highest proportion of teachers in state-tested subjects. This proportion decreases with each successive experience level. In other words, the least-experienced teachers within a school have the highest probability of teaching state-tested subjects, while the most-experienced teachers have the lowest probability of teaching these subjects.

What do these trends mean for Mississippi schools?

We cannot definitively conclude that teaching a state-tested subject is a direct cause of attrition, but it is nonetheless associated with a desire to exit the classroom. Based on past research, this could be due to factors such as decreased flexibility, increased pressure from school and district leaders, and the resulting burnout. But regardless of the specific reasons for this pattern, increased attrition risk for state-tested teachers is troubling, particularly if the desire to leave translates to a higher turnover rate for these teachers.  Increased turnover has been shown to negatively impact student achievement in ELA and math, and it can be particularly detrimental in schools that have large populations of low-performing students and Black students. Unfortunately, we already see the highest rates of turnover at these types of schools.

There are multiple avenues through which high turnover can impact student achievement. To name one, teachers who quit are often replaced with new, inexperienced teachers. This pattern holds relevance for our analyses, as we observe that state-tested teachers’ high attrition risk has likely contributed to a workforce in which early-career educators are most likely to teach state-tested subjects. Experience is an important element of teacher quality, and there is a particularly large learning curve in the first several years of a teacher’s career. Numerous studies have found that the experience of ELA and math teachers is positively correlated with student achievement on standardized tests. The experience level of teachers in these subjects has also been demonstrated to impact non-test-related outcomes, such as student absenteeism. Students are at a disadvantage if teachers with the least experience are placed in these subjects at the highest rates. 

This brings us to a larger point: the consequences of teacher shortages fall most heavily on our students. We owe it to them to work towards solving this issue. Teaching a state-tested subject is one among many forces that is connected to a teacher’s risk of attrition. At Mississippi First, we are in the process of disentangling more of these factors and using our analyses to develop targeted policy solutions. We look forward to sharing more of this work in the coming months.
