Equal Protection and Public Education Access for Immigrant Students: A 50-State Review

Introduction to Plyler v. Doe

Immigration has long been a complex issue in this country, consistently ranking as a concern for voters and appearing in political debates in the nation’s capital and in statehouses across the country. President Donald Trump’s 2024 campaign focused heavily on immigration. Once elected, Trump made several immigration-related changes, including withdrawing long-standing guidance discouraging immigration enforcement in “sensitive locations,” such as schools.¹ The issue became more visible — and more divisive — later in 2025 with the increased presence of federal immigration enforcement officers in American cities.

The focus on immigrant students and their families dates back more than four decades to the landmark U.S. Supreme Court case Plyler v. Doe (1982), which determined that undocumented immigrant students are entitled to the equal protection of laws that allow other children to attend K-12 public schools free of charge. Since 1982, there has been opposition to Plyler, with at least three states directly challenging the decision. This legal precedent is increasingly under threat. In the most recent legislative session (2025-26), five states introduced measures to restrict access protected by this decision, setting up a legal confrontation.² In February 2026, the Heritage Foundation, an influential conservative think tank, encouraged more states to take steps to challenge the decision.³ And in March 2026, Congress held a hearing to examine arguments against Plyler.⁴

This resource introduces the Plyler case and its related principles, and it provides an overview of the Court’s decision and its reasoning. It summarizes the current state of legislation and other public signals of potential state action, using maps that illustrate the current national landscape of activity advancing or challenging the principles of Plyler. It also summarizes research on expanding and restricting access to public schools — a proxy for the potential impacts of overturning Plyler.

History and Holding of the Case

In Plyler v. Doe (1982),⁵ the U.S. Supreme Court confronted the question, “Does the Constitution protect access to free public K-12 education for all immigrant students, even those who are undocumented?”⁶ The case involved a challenge to a Texas law barring the use of state funds to educate children who were not “legally admitted” into the United States.⁷ In practice, that policy allowed school districts to charge tuition for undocumented students — and to deny enrollment to those who could not pay. 

Texas’ defense of the law relied on three arguments:¹¹

1. Denying access to public education would discourage undocumented immigration into Texas.
2. Educating undocumented students placed undue financial strain on school districts.
3. The state should be relieved of the obligation to educate children who might not remain in Texas.

The Supreme Court rejected each of those arguments as not amounting to sufficient state interests to overcome the guarantees of the Constitution. As a result, the Court concluded that the Texas statute violated the Equal Protection Clause of the 14th Amendment by denying children access to public education based on their immigration status. The Court reasoned that denying undocumented children access to education would impose a “lifetime hardship” on children who were not responsible for their immigration status and were powerless to change it.¹²

Although the Plyler decision focused specifically on tuition, its reasoning establishes broader principles that guide how public education systems should serve immigrant students:¹⁴

• Undocumented children are “persons” and are entitled to the protections of the 14th Amendment. 
• An otherwise free public K-12 education system cannot deny enrollment or charge tuition to students based on their immigration status. 
• Public education plays a unique role in American life. Beyond academic education, public schools prepare children to participate in civic life and help sustain the nation’s “political and cultural inheritance.” The fiscal savings that Texas argued might result from preventing undocumented children from enrolling in a public school were not sufficient to justify the exclusion of those students from school. 

In addition, some interpretations extend Plyler’s reasoning to other educational programs and services as well as additional, nonmonetary barriers to access.

The Plyler decision established a clear constitutional principle: Children living in the United States cannot be denied access to public education on the basis of their immigration status.

In order to change the law, the U.S. Supreme Court would need to overturn Plyler v. Doe. Procedurally, this would require a state to first pass legislation similar to the laws originally challenged in Texas. If such a law were passed, that would kick off a sequence of legal challenges and appeals until it eventually worked its way up to final review at the Supreme Court. If the Supreme Court did then accept the case and revisit Plyler, federal law could change nationwide —– but states would retain the power to update their own laws, if and as they chose to. 

Maps: An Interactive 50-State Landscape

A majority of American parents support providing public education regardless of status. In a recent National Parents Union poll of over 1,500 parents of public school children, 66% strongly or somewhat support “continuing to allow undocumented immigrant children who are living in the U.S. to attend K-12 public schools in the U.S., as is required by law.”¹⁵

Given the evidence of myriad educational, social, civic, and economic benefits created by the long-standing policy established by Plyler v. Doe, its legacy should be carefully reviewed and considered by organizations and states interested in disrupting or overturning its protection of access to public education for immigrant students, regardless of status.

Over the past year, many states have considered or enacted legislation aimed at protecting or challenging the holding of Plyler. This analysis maps the activity occurring in each state with respect to Plyler (Maps 1-5; Appendix).

Table: Comprehensive Legislative Scan

As shown in Map 3, 43 states have introduced, advanced, enacted, or failed legislation in 2025 or 2026 that affects access to education for immigrant students in some way. This includes direct attempts to codify or challenge the holding of Plyler at the state level, or other legislation intending to change a state’s current policies around immigration enforcement in schools, data collection on students’ and/or families’ immigration status, funding structures for undocumented students, or access to vouchers. These legislative groupings are categorized as “principles of Plyler” in this analysis, defined as any actions that — although not formal components of the Plyler holding — establish or restrict access to the full range of programs, supports, and services that enable students to learn and participate in school.

The Table below provides a detailed overview of all 2025 and 2026 state legislation directly attempting to codify or challenge the holding of Plyler as well as indirect actions related to the principles of Plyler.

Note: This tracking is accurate as of April 30, 2026. Due to the rapidly evolving nature of the legislative process, some of the information presented in the Table may not be fully up to date.

Effect on Public Education

Plyler has been federal law for more than 40 years, and no studies directly forecast the consequences of overturning it. However, research and data on related issues — such as attendance, school closures, and early childhood programming — help to illustrate the benefits of school access regardless of immigration status. This protection, currently guaranteed by the Court’s holding in Plyler, would be at risk if the decision were overturned.

Access to K-12 Public Education, as Protected Under Plyler, Benefits Society 

Access to public education is good for children

Chief Justice Warren Burger opened the Plyler dissent by stating that he “would agree without hesitation that it is senseless for an enlightened society to deprive any children … of an elementary education.”¹⁶ Even in disagreement over constitutional doctrine, the Court recognized that education serves children’s basic developmental and social needs. In addition to academic learning, school-based programming provides social-emotional learning to students, shown to improve student “academic achievement, school functioning, social and emotional skills, attitudes, behaviors, and perceptions of school climate and safety.”¹⁷ Regularly attending school “is important to students’ learning, well-being, and development.”¹⁸ Students who regularly miss school experience lower academic performance and social alienation.¹⁹ School attendance research indicates “each additional year of compulsory schooling produces about 7.3–8.2% increase in adulthood weekly income.”²⁰

Access to public education is good for the country

Public education improves democracy, creates broad economic returns, and reduces crime. Specifically, public education contributes to a “stable and effective democracy,” with increased educational opportunities “instilling in students a sense of civic responsibility.”²¹ Providing public education to all children benefits society as a whole by generating economic returns that extend well beyond the individual student. The strongest causal evidence shows that increases in school funding raise educational attainment and earnings and lower the incidence of adult poverty.²² Education also creates broader social savings by improving public safety, with high school graduation shown to reduce crime and criminal incarceration.²³

Education builds civil society

Civil society benefits from public education because it fosters community cohesion, provides a safe and reliable daytime setting for children, and offers social and civic benefits to students and families. 

Researchers describe schools as “adaptive ecosystems … that span social, cultural, political, and economic dimensions.”²⁴ Public schools support both individual well-being and collective stability. Families rely on schools as embedded institutions whose purpose and role are molded by their connections with families, teachers, communities, governing structures, and historical contexts.²⁵ 

Public education also provides sociocultural adaptation, civic socialization, and a sense of belonging for children. Research on language development shows that young children can learn and use two languages fluently, which can ease their transition into a new society while preserving ties to home and family.²⁶ Immigrant students and their families often build the knowledge, skills, and sense of responsibility needed for civic engagement through involvement in school activities, social networks, and other opportunities. In this way, public schools can serve as important spaces where children and youth find connection and a sense of belonging.²⁷

Public schools primarily focus on educating children, but they also play a significant role in providing parents with a safe, supervised place for their children during the day.²⁸ That function matters for family stability as much as it matters for children’s daily well-being. Families rely on safe, dependable schools for their children, freeing them to work, care for others, or fulfill educational obligations. 

By providing a safe environment for children, public education offers additional benefits to society, including increased workforce participation, which in turn leads to broader economic benefits for individuals and communities.

As an analogy, early childhood education (ECE) studies indicate that caring for children makes it easier for parents to join the labor force, where reduced costs and “increased availability of public ECE increases ECE attendance among young children, and has positive impacts on mothers’ labor force participation and work hours.”²⁹ Moreover, when children lack access to school, one study found that both men and women experience disruptions to their work, including reduced hours and a lower likelihood of full-time employment. Women were more likely to leave the job market entirely. Overall, these disruptions led to declines in earnings for the parents of school-age children.³⁰

Education builds a stronger economy and a better workforce for the future 

Public education not only enhances labor force participation by family members of children, but it also helps build a stronger workforce over time. One researcher noted that ”the existing evidence makes a strong prima facie case that changing the skills of the population [through education] will lead to higher [economic] growth rates.”³¹ Data from the U.S. Department of Labor Statistics in 2024 show that high school graduates earn roughly $200 more weekly and are unemployed at a rate 2% lower than those who do not complete high school.³²

Policy research on families who benefited from Plyler v. Doe found several economic benefits for their communities, their family members, and the country. These include:³³

• State and local taxes paid by Plyler beneficiaries exceed the cost of educating these children by over $600 billion.
• Plyler beneficiaries will contribute an estimated $2.71 trillion to U.S. GDP over their lifetimes.
• Plyler helps keep children out of poverty.
• Nearly one-fifth of more than 350,000 adult beneficiaries “work in industries that typically require many college-educated workers, with 45,000 Plyler beneficiaries working in elementary and secondary schools and 42,000 in hospitals.”
  

Public K-12 districts benefit from student funding

Discouraging immigrants from attending public schools may tighten school budgets. Many districts receive state funding based on enrollment or attendance formulas; if students are blocked from education or are afraid to attend, districts could lose those per-pupil dollars. These additional enrollment and attendance effects, along with the current declining enrollment forecasts and the expiration of federal COVID-era funding, could put impacted districts in a financially tenuous position.³⁴ States also receive federal funding to support English learners and immigrant students through Title III grants that may be proportionally reduced if students avoid, or are banned from, public schools.³⁵

Interfering With Access Complicates the Public Good Associated With K-12 Education

Attempts to curtail immigrant access to education have negative effects. Studies on the effects of increased immigration enforcement — the best available proxy for what the U.S. could expect if enrollment were to be inhibited — indicate that such activities undermine the individual and collective benefits generally associated with public education. One can infer that changing the laws that protect enrollment would have similar effects on these student populations.

Inhibiting K-12 access decreases school enrollment and attendance for both immigrant and U.S.-born students

Threats to education access can depress enrollment and attendance for all students. Efforts to enact public education policy even indirectly counter to Plyler show the detrimental effects of rolling back access for undocumented families and students. For example, researchers studied a 2011 measure adopted by Alabama’s legislature, subsequently overturned, that required schools to determine the immigration status of new students — and then compile and report that information to the state.³⁶ They found that this law led to a significant increase in absenteeism among Latino students and created fear and confusion for the school community.³⁷ Additional studies show that heightened interior immigration attention in early 2025 was linked to a sharp rise in school absences, with one study finding a 22% increase in daily absences following enforcement actions — especially among younger students.³⁸ This research indicates that when immigration arrests increase, the result is “substantial declines in enrollment among Hispanic youth, including U.S.-born, foreign-born, and individuals in mixed-status families.”³⁹

Limiting, restricting, or inhibiting K-12 access for some students can reduce academic performance for all students

A large body of research shows that increases in student absenteeism contribute to declining academic outcomes and can affect all students, not just those who are absent. One study found that as more classmates are absent, individual students’ performance declines, with consistent negative effects on both academic achievement and executive functioning skills.⁴⁰ In addition, immigration enforcement itself has also been shown to result in decreased academic outcomes for immigrant and U.S.-born students, particularly at the middle and high school levels: Researchers found evidence that increases in immigration activity reduced test scores for both U.S.-born and foreign-born Spanish-speaking students.⁴¹
