Last updated 3 days ago. Our resources are updated regularly but please keep in mind that links, programs, policies, and contact information do change.

Charter schools have become an increasing part of the U.S. educational landscape. The number of these schools has grown substantially, increasing from approximately 5,300 in the 2010-11 school year to 7,800 in the 2021-22 school year. During this same period, student enrollment more than doubled from 1.8 million to 3.7 million students.

What Are Charter Schools?

Definition and Basic Structure

The U.S. Department of Education defines a public charter school as a publicly funded school that operates under a legislative contract, known as a charter, with the state, district, or another authorized entity.

This contractual agreement grants charter schools flexibility and autonomy, exempting them from certain state or local rules that govern traditional public schools. In return for this operational freedom, charter schools are held accountable to specific educational objectives and performance standards outlined in their charter.

Charter schools function as schools of choice, meaning students apply to enroll. They cannot charge tuition or be affiliated with any religious institution, adhering to regulations applicable to all public schools.

Key Principles and Development Process

Accountability and autonomy are the foundational principles that distinguish charter schools:

• Their accountability is demonstrated through their reliance on families choosing to enroll their children and through their performance contract with an authorized chartering agency.
• Their autonomy provides them with greater flexibility in operations and management compared to traditional public schools, allowing for innovation in educational approaches, curriculum development, and resource allocation.

The journey of a charter school typically involves several stages:

1. Design and Planning: An individual or group identifies an unmet educational need and develops the school’s mission, governance structure, budget, and funding sources.
2. Authorizing Period: The prospective charter school operator submits a detailed application to a charter school authorizer for approval.
3. Preparing to Open: The process includes hiring staff, creating curriculum, defining policies, planning activities, and securing a suitable facility.
4. Enrollment and Operations: Charter schools accept students through an application process, using lottery systems when applications exceed capacity.
5. Achieving and Sustaining Success: Authorizers regularly review performance against charter terms.
6. Replication and Expansion: Successful charter schools may expand their model to serve more students.

History and Growth

Origins and Legislation

The charter school movement traces its origins to the alternative schools reform models of the 1960s. The first legislative framework allowing for public charter schools was enacted in Minnesota in 1991.

Since then, the concept has spread across the nation, with 45 states and the District of Columbia having passed public charter legislation as of fall 2021. The states without such legislation were Montana, Nebraska, North Dakota, South Dakota, and Vermont. While Kentucky and West Virginia had passed charter legislation, they had no operating charter schools in 2021.

Expansion Trends

Charter schools have experienced substantial growth since their inception:

• In the 2002-03 school year, there were approximately 2,575 charter schools operating in 35 states and the District of Columbia, serving about 1.4% of all U.S. public school students.
• By the 2006-07 school year, this number increased to 4,132 charter schools across 40 states and the District of Columbia, serving roughly 2% of public school students.
• Between the 2010-11 and 2021-22 school years, the number of public charter schools rose from approximately 5,300 to 7,800.
• During this same period, student enrollment more than doubled from 1.8 million to 3.7 million.

Geographic Distribution

The prevalence of charter school enrollment varies considerably by state:

• As of fall 2021, the District of Columbia had the highest percentage of public school students enrolled in charter schools (45%), followed by Arizona (20%).
• Eight additional states – Colorado, Nevada, Florida, Louisiana, Delaware, California, Utah, and Michigan – had between 10% and 15% of public school students enrolled in charter schools.
• Seven states had less than 1% of their public school students in charter schools.

This growth occurred alongside a decrease in the number of traditional public schools, which declined from 93,500 to 91,400 between 2010-11 and 2021-22. Consequently, the percentage of all public schools that were charter schools increased from 5% to 8% during this period.

Federal Government’s Role

Support and Oversight

The federal government supports and oversees charter schools through the U.S. Department of Education, particularly via the Office of Elementary and Secondary Education (OESE) and its Charter School Programs (CSP) Division.

The CSP Division provides funding for key activities:

• Supporting the creation of new public charter schools
• Facilitating the replication and expansion of existing high-quality public charter schools
• Disseminating information about effective practices identified within charter schools

To ensure funds are directed toward high-quality initiatives, the Department employs a discretionary grants peer review process involving non-federal, independent individuals with diverse backgrounds and expertise in education.

Federal Definition and Policy Goals

The federal definition of a charter school, outlined in the Elementary and Secondary Education Act (ESEA), includes key characteristics such as:

• Being established under a specific state statute authorizing charters
• Being exempt from significant state or local rules that inhibit flexible operation
• Operating under public supervision
• Pursuing specific educational objectives
• Providing elementary or secondary education
• Being nonsectarian
• Admitting students through parental choice and lottery if oversubscribed
• Complying with federal and state audit requirements
• Meeting health and safety standards
• Operating in accordance with state law
• Having a written performance contract with an authorized public chartering agency

The primary federal policy goals related to charter schools are:

• Expanding the number of high-quality options available to students nationwide
• Enhancing parent and student choices within the public education system

State Authority

While the federal government provides funding and sets certain guidelines, the establishment, regulation, and overall framework for charter schools are largely determined at the state level.

Recent policy shifts have emphasized respect for state autonomy. The Department of Education has taken steps to reduce federal overreach in Charter School Program grant awards, returning educational authority to the states, reducing bureaucratic processes, and expanding school choice options for students and families.

Enrollment, Demographics, and Academic Outcomes

Enrollment Trends

Charter school enrollment has seen a significant upward trajectory:

• Between fall 2010 and fall 2021, charter school enrollment more than doubled, increasing from 1.8 million to 3.7 million students.
• This growth contrasts with traditional public schools, which decreased by 4% during the same period.
• During the initial phase of the COVID-19 pandemic (between fall 2019 and fall 2020), traditional public school enrollment declined by 4%, while public charter school enrollment increased by 7%.

Demographics

The demographic composition of public charter school students has shifted over time:

• Between fall 2010 and fall 2021, the percentages of students who were Hispanic, of Two or more races, and Asian increased, while the percentages of White and Black students decreased.

When comparing charter schools to traditional public schools (data from fall 2016):

• A higher percentage of charter school students were Black (26% vs. 15%) and Hispanic (33% vs. 26%)
• A higher percentage of traditional public school students were White (49% vs. 32%) and Asian/Pacific Islander (6% vs. 4%)

Socioeconomically, in fall 2021, 31% of public charter school students attended high-poverty schools (where more than 75% of students are eligible for free or reduced-price lunch), compared to 21% of traditional public school students.

Academic Outcomes

Academic performance comparisons between charter and traditional public schools show mixed results:

• In 2017, National Assessment of Educational Progress (NAEP) data showed no measurable differences in average reading and mathematics scores of 8th-grade students in traditional public and public charter schools.
• Similarly, no measurable differences were observed in 4th-grade reading scores between the two school types.

Research on the broader impact of charter schools has yielded varied findings:

• A study on charter middle schools found that admission did not significantly affect students’ college enrollment or degree attainment on average.
• Other research suggests that charter entry can lead to increases in high school graduation rates and test scores at the district level.

The effectiveness of charter schools can vary significantly depending on factors such as location, the specific model implemented, and the characteristics of the student population served.

Resources for Parents and Families

The U.S. Department of Education provides various resources to help parents understand charter schools and make informed decisions about their children’s education.

The School Choice section on the Department’s website serves as a central hub for guidance related to various school choice options, including charter schools. Within this section, parents can find detailed information about Charter School Programs, which encompass federal grant initiatives.

For parents interested in understanding their role in charter schools, the Department’s resources highlight the potential for greater parent involvement and innovative engagement strategies within these schools. Many charter schools, particularly those in urban areas serving diverse student populations, actively foster strong partnerships with families. Some schools even use parent contracts to encourage active participation.

The Education Statistics section offers valuable data and research about public school settings, including comprehensive information on charter schools. Parents can also explore resources from national school choice education organizations, a list of which is available on the Department’s website.

What Parents Should Consider

When considering charter schools, parents often prioritize factors such as:

• Quality of teachers and staff
• Safety and disciplinary environment
• Focus of curriculum and academic performance
• Class sizes

For parents contemplating enrolling their child in a charter school, actionable advice includes:

• Inquiring about the school’s approach to parent involvement
• Checking the availability of support for basic family needs
• Understanding the methods of communication employed by the school
• Learning about the specific mission and values that guide the school’s operation

Accountability Measures and Performance Standards

Charter schools operate under a framework of accountability that is central to their unique status within the public education system. They are primarily accountable to the authorizing agency that granted their charter and must adhere to specific standards and expectations outlined in this legislative contract.

These authorizing agencies, which can include states, local education agencies, colleges, or independent non-profit organizations, set the academic and operational expectations for charter schools and oversee their performance.

Performance Evaluation

Charter schools are evaluated through performance contracts, which stipulate academic, financial, and organizational benchmarks. Decisions regarding renewal, revocation, or non-renewal of a charter are heavily influenced by the school’s ability to demonstrate satisfactory progress toward these goals.

Federal guidelines emphasize:

• Establishing measurable academic and operational performance expectations
• Providing annual public reports on the performance of charter schools
• Using student academic achievement increases as a key factor in renewal decisions

The federal government is concerned with ensuring continued accountability of charter schools, particularly during transitions to new state assessments or accountability systems. Charter schools are expected to be monitored at least annually, with in-depth reviews conducted periodically.

Recent federal regulations have aimed to enhance transparency and accountability within the charter school sector, especially for schools receiving funding through Charter School Programs. These regulations include requirements for grantees to disclose management contracts with for-profit entities and to provide clear information about their enrollment policies.

Comparing Charter Schools with Traditional Public Schools

While both charter schools and traditional public schools are publicly funded institutions with the shared goal of educating students, they exhibit several key differences and similarities.

Governance and Autonomy

One of the most significant distinctions lies in governance and autonomy:

• Charter schools typically operate under the oversight of a group or organization through a charter agreement, which often exempts them from certain state and local regulations.
• Traditional public schools are generally governed by local school districts and are subject to a broader range of state and local rules.

Shared Characteristics

Despite these differences, both types of schools share fundamental characteristics:

• Both are publicly funded
• Both are held accountable for performance, although through different mechanisms

Enrollment and Demographics

Enrollment trends have shown a divergence:

• Between fall 2010 and fall 2021, public charter school enrollment increased significantly
• Traditional public school enrollment decreased over the same period

The demographic composition has shown similar overall trends, with increases in Hispanic and Asian student populations and decreases in White and Black student populations. However, charter schools tend to have a higher percentage of Black and Hispanic students compared to traditional public schools.

Academic Performance

Findings from academic performance assessments have not shown a consistent advantage for either charter or traditional public schools. In 2017, there were no measurable differences in average 8th-grade reading and mathematics scores between students in both types of schools.

District Impact

The growth of the charter school sector can affect traditional public school districts in various ways:

• Some districts report budgetary effects
• Districts often respond by implementing new educational programs
• Many districts increase their focus on parent involvement and public relations

This suggests that the presence of charter schools can create both competitive pressures and opportunities for innovation within the broader public education system.

Innovation and Successful Models

The operational flexibility afforded to charter schools often fosters diverse innovative educational models and practices. This autonomy allows them to be more creative and responsive to specific student needs.

Diverse Approaches

Notable examples of innovation include:

• Intentionally diverse charter schools: Designed to attract and serve a student body that reflects broad community diversity in terms of race, ethnicity, socioeconomic status, and other factors
• Specialized programs: Many charter schools focus on specific needs or populations, offering programs tailored to particular learning styles or academic interests
• Enhanced parent involvement: Charter schools often implement stronger parent involvement policies compared to traditional public schools
• Technology integration: Some charter schools lead in utilizing technology and online learning models to expand access and personalize education

Serving Diverse Student Populations

Charter schools increasingly serve diverse student populations, including English Language Learners (ELLs) and students with disabilities:

• For ELLs, charter schools can offer instructional models tailored to linguistic and academic development. Some research suggests ELL students in charter schools may experience stronger academic gains in reading and math compared to peers in traditional public schools.
• Charter schools are obligated to provide meaningful access and quality education to students with disabilities, ensuring they receive the same rights and protections as students in other public schools.

While charter schools enroll growing numbers of students with disabilities, the proportion often remains lower than in traditional public schools, and some charter schools face challenges providing adequate resources for students with severe disabilities.

Conclusion

Charter schools have become a significant part of the U.S. education system. Their growth in number and enrollment over the past three decades indicates sustained interest from parents and educators in exploring diverse educational options within the public sphere.

Federal policy provides a framework of support and oversight, but the specific characteristics and regulations governing charter schools are largely determined at the state level, leading to a varied landscape across the country.

Statistical data reveal trends in enrollment and demographics that often mirror broader societal shifts but also highlight distinct differences between charter and traditional public school populations. Academic outcome studies present a nuanced picture, with effectiveness often depending on various school-level and student-level factors.

Resources are available to help parents navigate the charter school landscape, and accountability measures ensure these schools meet the expectations set in their charters. The innovative practices and models emerging from charter schools offer potential insights for the wider educational community.

As the charter school sector continues to evolve, relying on credible, data-driven sources remains crucial for understanding their impact and potential within the U.S. educational landscape.
