When were public schools started? The first free, tax-supported public school in the United States opened in 1639 in Dorchester, Massachusetts. However, the widespread system of public education we know today began to take shape in the early 1800s, led by reformers like Horace Mann.
Understanding this history helps parents and students appreciate why education is free and available to all children in America.
The First Public School in America
The very first public school in what would become the United States was established in 1639 in Dorchester, Massachusetts. This school was funded by local taxes and open to all children in the community, not just the wealthy.
Before this, most education happened at home or in private tutoring sessions. Only families who could afford to pay teachers sent their children to school.
Early Colonial Schools
In the New England colonies, towns were required by law to set up schools. The Massachusetts Bay Colony passed a law in 1647 called the “Old Deluder Satan Act.” This law required every town with 50 or more families to hire a teacher.
These early schools taught basic reading, writing, and religion. They were not like modern schools with grades and multiple subjects.
The Common School Movement (1830s–1850s)
The real answer to “when were public schools started” lies in the Common School Movement. This movement began in the 1830s, led by Horace Mann, who is often called the “Father of American Public Education.”
Mann believed that education should be free, universal, and non-sectarian. He argued that public schools would create better citizens and reduce crime.
By 1850, most northern states had established free public elementary schools. These schools were funded by local property taxes and open to all white children.
Key Reforms by Horace Mann
- Established the first state board of education in Massachusetts in 1837
- Created professional training for teachers through normal schools
- Lengthened the school year to at least six months
- Standardized curriculum including reading, writing, arithmetic, and geography
Expansion After the Civil War (1865–1900)
After the Civil War, public education expanded rapidly across the United States. The 14th Amendment, ratified in 1868, guaranteed equal protection under the law, which eventually helped support equal access to education.
By 1900, 34 states had compulsory attendance laws requiring children to attend school. Most children attended at least elementary school, though high school was still rare.
Southern states were slower to establish public schools due to resistance to educating African American children. It took many more decades to achieve truly integrated public schools.

Modern Public School System (1900–Today)
By the early 1900s, the structure of public schools looked similar to today. Students attended elementary school for grades 1 through 8, then high school for grades 9 through 12.
The federal government became more involved in education with the Elementary and Secondary Education Act of 1965. This law provided funding for schools with low-income students.
Today, public schools serve over 50 million students across the United States. They are funded by a combination of local property taxes, state funds, and federal grants.
Key Milestones Since 1900
- 1918: All states have compulsory attendance laws
- 1954: Supreme Court rules school segregation unconstitutional in Brown v. Board of Education
- 1965: Elementary and Secondary Education Act provides federal funding for disadvantaged students
- 1975: Education for All Handicapped Children Act guarantees education for students with disabilities
Why Knowing This History Matters Today
Understanding when public schools started helps parents advocate for their children’s education. Knowing that public schools were created to provide equal opportunity reminds us of their original purpose.
If you are a parent, you can use this history to talk with your child about the value of free education. Encourage them to appreciate the opportunities earlier generations fought to provide.
Public schools continue to evolve. As of July 2026, debates continue about school funding, curriculum standards, and technology in classrooms. But the core mission remains the same: to provide a free, quality education for every child.
In summary, public schools in the United States started with a single school in 1639, but the system we know today began with the Common School Movement in the 1830s. From colonial times to modern classrooms, public education has grown to serve millions of students and remains a cornerstone of American democracy.
