Hiring Local vs. Nonlocal Teachers: What the Evidence Shows

Hiring a teacher who graduated from a local high school versus recruiting from out of state presents a genuine trade-off. A July 2026 study from the University of Maryland, College Park tracked 35,246 novice public school teachers over more than a decade and found that local hires were 17 percentage points more likely to still be teaching in their home district after five years. Retention, however, did not translate into stronger student outcomes. Growing up locally had no statistically significant effect on math or ELA achievement.

For aspiring teachers weighing certification routes, and for M.Ed. students evaluating grow-your-own or residency options, the distinction matters. The preparation pathway a teacher completes predicted early-career effectiveness far more reliably than hometown roots.

What the Latest Research Actually Shows About Local Teachers

Local teacher hiring sounds like a straightforward teacher retention strategy, but the latest research separates two questions: who stays in a district and who improves student learning. A July 2026 study by Dominguez-Mel, Morris, Montana, and Blazar, reported in a FutureEd research note, uses Maryland Longitudinal Data System records from 2012-13 through 2023-24 to track 35,246 novice public school teachers.

Retention favors local hires

Teachers who graduated from a high school in the district where they later taught were 12 percentage points more likely to still be teaching there after three years, and 17 percentage points more likely after five years, compared with peers who did not. That is a meaningful stability advantage for districts looking to reduce early-career churn.

Effectiveness tells a different story

When researchers linked more than 12,000 elementary and middle school teachers to student test records, growing up locally had no statistically significant effect on student achievement. Math and ELA scores showed a small uptick, but the difference was not large enough to rule out chance. In other words, hiring local may keep classrooms staffed, but it does not by itself make those teachers more effective.

Why the distinction matters

Retention and effectiveness are separate outcomes. A hiring policy can win on one and lose on the other. National patterns reinforce this caution. In Colorado, Missouri, Nebraska, and South Dakota from 2015-16 to 2016-17, 82% of teachers stayed in the same school, 8% moved, and 10% left, with rural and nonrural rates nearly identical, but substantial variation across districts and only a one-year window.¹ National data for 2020-21 show 84% stayers, 8% movers, and 8% leavers, with cities slightly lower at 82% stayers.² Among novice teachers in urban districts across several states, about 55% leave their district and 70% leave their school within five years.³ So the local retention edge is real but context-dependent, and it should not be mistaken for proof of teaching quality.

Why Teacher Preparation Pathway Predicts Student Gains More Than Hometown

The debate over teacher quality has shifted from hometown loyalty to preparation quality, with early-career effectiveness now anchored to how teachers are trained rather than where they grew up. In the Maryland study of 35,246 novice teachers, the preparation pathway proved to be the stronger predictor of student math gains during teachers' first two years.

Where the local advantage fades

Teachers who completed the Teacher Academy of Maryland, a Maryland university teacher-preparation program, or a residency program such as Teach for America or Baltimore City Teacher Residency all produced statistically significant math gains. Residency-trained teachers showed the largest improvement, roughly double the gain of university-prepared teachers. Out-of-state trained teachers posted even higher math gains than any other pathway, but researchers attribute that result to hiring selectivity, not program superiority, so districts should not over-interpret those numbers. Conditionally certified teachers and those who entered through a classroom-aide-to-teacher pathway produced similar, more modest gains. The aide pathway is notable for retention: those teachers were more likely to remain in Maryland's teaching workforce long-term. Residency programs, by contrast, had similar retention to conditionally certified teachers through year three but were significantly more likely to have left by year five.

National research echoes a small, uneven signal

Across national studies and meta-analyses, differences in student achievement by preparation pathway are small, typically between 0.02 and 0.05 standard deviations¹, and concentrated in the first year or two. Some alternative programs show a tiny overall advantage of about 0.03 standard deviations², but that finding is not consistent across subjects or grade levels. Not all alternative routes outperform traditional ones: teachers with reduced coursework posted initial gaps of 2 to 5 percent of a standard deviation¹, differences that largely disappeared after the first year. Boston Teacher Residency graduates, for example, started no more effective than other novices in math but improved rapidly, surpassing veteran teachers by years four and five with gains up to 7 percent of a standard deviation³. Urban Teacher Residency students outperformed peers in 8 of 9 statistically significant comparisons⁴, though many residency studies do not report standardized effect sizes.

What this means for aspiring educators

The central takeaway is that the rigor and structure of your preparation program matter more for student outcomes than where you grew up. If you are choosing between a local connection and a stronger training pathway, the research points toward the training pathway. Grow-your-own and residency models can support retention, but they should be evaluated on student achievement, not just local hiring.

Preparation Pathway Comparison: Retention Vs. Effectiveness at a Glance

The Maryland Longitudinal Data System study tracked over 35,000 novice teachers from 2012-13 through 2023-24, revealing a core tension: the pathways that produce the strongest early-career student achievement gains are not always the ones that keep teachers in the classroom longest. This comparison draws on findings for five preparation routes. Note that the out-of-state pathway's strong math results likely reflect selective hiring, not transferable program quality.

Do Grow-Your-Own Programs Actually Improve Student Achievement?

Grow-your-own (GYO) programs are structured pipelines: high school teaching academies, paraprofessional or aide-to-teacher routes, and community college teacher certification pathways designed to move local residents into the classroom. The usual case for GYO rests on hiring locally and keeping teachers longer. The harder question is whether those locally sourced teachers improve student learning.

The evaluation gap is real

Published GYO evaluations rarely measure K-12 student achievement. A 2025 REL Northwest scan did not identify any GYO programs that rigorously evaluate long-term impact such as changes in student achievement. A 2023 NPR synthesis of GYO research found that studies link GYO to higher retention, teacher diversity, and broadly described "better student outcomes," but none provide a counterfactual for causal attribution. An Illinois evaluation similarly notes that consortia do not show evidence that their evaluation process examines educational outcomes in partner schools.¹ A South Texas university GYO program reported that all 24 participants in one cohort were employed as teachers and felt better prepared in classroom management and community engagement, but it did not report student test-score outcomes.²

What Maryland's GYO program shows

Teacher Academy of Maryland offers one of the stronger published evaluations. Attending a TAM high school increased the likelihood of later teaching in Maryland public schools by 0.6 percentage points, a 47 percent relative increase.³ The effect was concentrated among White girls and Black girls.³ The program also raised high school graduation slightly and increased average wages by about 5 percent, with an 18 percent gain for Black girls.³ These are real pipeline and labor-market results, but the evaluation does not report test-score effects for the students those teachers later serve.

The aide-to-teacher route is a closer match

In the Maryland teacher localness data, teachers who had worked as classroom aides before entering the classroom produced academic gains similar to conditionally certified teachers and were more likely to remain in Maryland's teaching workforce long term. That suggests a GYO-adjacent pathway can combine classroom effectiveness with strong retention, but even here the achievement evidence is tied to a specific state dataset and should not be generalized too far.

Build outcome tracking in from the start

The 2026 Maryland study recommends evaluating GYO programs on student achievement impact, not just local hiring. For districts, that means designing achievement outcome tracking into the program's data plan from day one, rather than retrofitting it later. Without that, GYO programs may prove they hire locally and retain teachers without ever showing whether student learning improves.

Teacher Salaries and Career Context for Local and Non-Local Hires

More than two million elementary and middle school teachers work in U.S. public and private schools, making this one of the largest professional workforces in the country. The table below presents 2024 national salary benchmarks from the Bureau of Labor Statistics. For aspiring teachers and M.Ed. students weighing preparation pathways, these figures provide a concrete earnings baseline. Notably, current salary structures rarely differentiate pay by preparation route or measured effectiveness, a gap that may undercut the very policy goals the Maryland study recommends. BLS projects a negative two percent employment change for elementary and middle school teachers from 2024 to 2034, though roughly 131,500 combined annual openings (91,000 elementary and 40,500 middle school) are still expected due to retirements and turnover. Keep in mind that salaries vary substantially by state and metro area, so educators should research local pay scales when planning their careers.
