A Growing Movement
Since 1991 when Minnesota enacted the first state law permitting charter schools, the idea of chartering has meant educational choice and opportunity. Today, 44 states, D.C., and the territories of Guam and Puerto Rico offer this educational option to students, families and communities.

Introduction
Charter Public Schools: Transforming Public Education
The American idea—the idea that a self-governing society of free and equal people who are “endowed by their creator with the right to life, liberty, and the pursuit of happiness" can flourish—continues to inspire hope in people around the world.
The success of the American idea rests upon the education and civic virtue of America’s citizens. Public schools were founded to prepare a rising generation for citizenship. These schools began in a democratized and decentralized way, first in the Northeast, then spreading westward as our nation grew. Over time, local public schools formed into state-led school systems intended to provide a common experience to unite a diverse nation.
As school systems became more well-established, they became rigid in design, inequitable in outcomes, and unable to meet the increasingly diverse expectations of people in post-war American society.
Pioneering educators, though, offered a better way. They began harnessing the power of autonomy for site-based management to better respond to student needs and empowering parents with choice. These early efforts showed that liberating public education from “the system”—what we today call “charter schools”—was not only possible, but would transform public education to advance the American idea.
Charter schools were first enacted into law in Minnesota in 1991, put into action by authorizers and school founders, and are now embraced by families throughout the nation for the better outcomes achieved for their kids.
This timeline explores the history of charter schools: from idea to action, to today. It is the history of a movement that continues to transform public education by inviting new people and organizations with good ideas on how to get better results for kids to try them. It is a study in how the people in this movement contribute to the success of the American idea by preparing the rising generation for the pursuit of happiness.

A Nation at Risk: The Report that Changed the Arc of Education

Special commissions on education are common, but none have had the same transformational impact as the 18-member National Commission on Excellence in Education. The Commission’s 1983 report, A Nation at Risk: The Imperative for Educational Reform, showed how complacent public education was jeopardizing America’s global competitiveness. This report sparked a new era of reform — an era in which the charter schools idea took shape.

The Launch of an Idea

A Nation at Risk created a new sense of urgency for improving education. One champion of this was the president of the American Federation of Teachers, Al Shanker. In a 1988 speech, Shanker proposed a bottom-up solution that empowered teachers with new, professional opportunities to best educate their students. The Minnesota Citizens League, led by Ted Kolderie, began building on the "charter idea"and how to put it into effect.

America’s First Charter Schools Law

Minnesota’s October 1988 Itasca Seminar brought AFT President Al Shanker and others together with state leaders and policymakers. Minnesotans in attendance included the Citizens League’s Ted Kolderie and the sponsor of the state’s open enrollment legislation, state Sen. Ember Reichgott. There, Reichgott became interested in introducing a charter schools bill. This bill failed in 1989 and 1990. A compromise was passed in 1991 that allowed up to eight “outcomes-based” schools to be created.

Chartering Spreads Throughout the Nation

In 1992, California became the second state to enact a charter schools law. Sponsored by state Sen. Gary K. Hart, this law was pivotal for the national advancement of chartering because it signaled that this emerging policy could take hold in large, diverse states. The following year, legislatures in five states — Colorado, Massachusetts, Michigan, New Mexico, and Wisconsin — enacted charter laws.

The Business Sector Enters Public Education

Another idea to improve education was emerging alongside the idea of charter schools: bringing business-based principles to public education via a new type of company called an educational management organization (EMO). The first of these was the Edison Project in 1992. Though EMOs have largely yielded to their nonprofit counterparts, National Heritage Academies and Charter Schools USA remain exemplars of quality at scale.

Advocates and Implementers Join the Movement

Leaders in the nascent charter schools movement were developing the institutions necessary for sustainability. By 1995, state and national organizations had begun to emerge. These included the Center for Education Reform, the Michigan Resource Center for Charter Schools, and, later, the Charter Friends National Network. Today, the Michigan Resource Center serves the national community as the National Charter Schools Institute.

A Presidential Call for Growth

When Arkansas’ democratic Governor Bill Clinton ran for president in 1992, part of his education agenda was charter schools. He advanced this policy in 1994 by helping create a federal Charter Schools Program that funded states to develop new schools. Clinton’s 1997 State of the Union address included a bold goal of creating 3,000 charters by 2000. His support of charters set a precedent that other presidents have followed.

Scaling What Works Through CMOs

Revisions to California’s charter schools law created the opportunity for a new kind of charter organization — multi-school networks now known as Charter Management Organizations (CMOs). These new organizations had some advantages: they brought scale, shared resources, and strategic support to the schools they operated. The nation’s first major CMO, Aspire Public Schools, launched the same year.

One Voice, Many Advocates: The National Alliance for Public Charter Schools

In 2005, the National Alliance for Public Charter Schools was founded to unify a growing patchwork of state and local advocates. As more charter schools opened, the need for coordinated policy, research, and messaging became urgent. The Alliance gave the movement a central voice — shaping debates, defending gains, and building coalitions.

Charter Enrollment Tops One Million Students

When the total enrollment for charter schools reached more than one million students in 3,600 schools across 40 states, chartering proved to be both scalable and sustainable. It also represented a pivot in the charter strategy: new schools were opening to replicate success, rather than to solely try new ways to educate students. This was most evident in New Orleans, where national networks were invited to transform the city’s system of schools in the wake of Hurricane Katrina.

Chartering in the National Spotlight

The release of Waiting for “Superman” culminated a period of increasingly popular support for charter schools' growth. Support for this was a moment of bipartisan unity in the 2008 presidential campaign. In 2009, President Barack Obama’s Race to the Top grant program prompted many state legislatures to lift caps that limited charter growth. In 2010, Facebook founder Mark Zuckerberg made an unprecedented $100 million pledge to transform Newark’s public schools, much of it tied to charter growth.

A Changing Political Climate

By 2016, political and public support for charters began to wane. A high-profile Massachusetts ballot initiative to allow for charter growth decisively failed. Teachers’ unions sharpened their opposition, launching campaigns like “Kids Not Profits.” Support from Democratic leaders cooled — most notably during the 2020 presidential race, when candidate Joe Biden aligned closely with union leaders. Though political support was declining, charter enrollment grew to more than 3.7 million students nationally by the fall of 2021.

Resilience, Protest, and Policy Renewal

The COVID era proved charter schools’ value to many families, especially those needing flexible and responsive learning. Enrollment grew — but the Biden Administration proposed regulations to the federal Charter Schools Program that threatened to limit access. In response, thousands of charter parents rallied at the White House in protest. Meanwhile, new data showed strong academic gains, and policy breakthroughs occurred in many states.

St. Isidore of Seville Catholic Virtual School v. Drummond

In April 2025, the U.S. Supreme Court heard arguments in the first case it has taken up about charter schools. Originating from Oklahoma, St. Isidore of Seville Catholic Virtual School v. Drummond raised important questions about chartering and the First Amendment. In a 4-4 split, the Court preserved the Oklahoma Supreme Court's decision that prevents religiously affiliated charters from opening in that state.
