Private vs. Public Schools: What's the Difference?
Cost
Public schools cannot charge tuition. They are funded through federal, state and local taxes. When you pay your taxes, you are paying for your child's education and the education of other children in your community.
Private schools cost money. Private schools do not receive tax revenues, but instead are funded through tuition, fundraising, donations and private grants. According to the National Association of Independent Schools (NAIS), the median tuition for their member private day schools in 2005-2006 in the United States was close to $14,000 for grades 1 to 3, $15,000 for grades 6 to 8 and $16,600 for grades 9 to 12. The median tuition for their member boarding schools was close to $29,000 for grades 1 to 3, $32,000 for grades 6 to 12. Note that of the 28,384 private schools in the United States, about 1,058 are affiliated with NAIS. The Digest of Education Statistics 2005 from the National Center for Education Statistics (NCES) reports that for the 1999-2000 school year, the average private school tuition was about $4,700.
Public or Private? The Debate Rages
Private school students typically score higher than public school students on standardized tests, but a study by the National Center for Education Statistics released in 2006 that took into account students' backgrounds told a different story.
Public school students in fourth and eighth grade scored almost as well or better in reading and math, except that private school students excelled in eighth-grade reading. (Downloading the PDF file of the study requires Adobe Acrobat Reader, which you can download for free if you click here.)
A Harvard University study challenged the results, using the same data but different methods. Researchers found that private schools came out ahead in 11 of 12 comparisons of students.
Earlier in 2006, an analysis of math scores by two University of Illinois researchers found similar results to the NCES study. The authors of Charter, Private, Public Schools and Academic Achievement found that "after accounting for the fact that private schools serve more advantaged populations, public schools perform remarkably well, often outscoring private and charter schools."
But as this dissenting view from the Thomas B. Fordham Foundation's Education Gadfly newsletter shows, the debate over which schools do a better job is far from settled.
Parochial schools generally charge less. According to the National Catholic Educational Association, in their annual statistical report in 2005-2006, the average elementary school tuition for Catholic schools (in 2005) was $2,607; the average freshman tuition (for 2002-2003) was $5,870. Catholic Schools enroll more students (49%) than any other segment of private schools.
Admissions
Public schools admit all children. By law, public schools must educate all children, including students with special needs. To enroll in a public school you simply register your child by filling out the necessary paperwork.
Private schools are selective. They are not obligated to accept every child, and in many private schools admission is very competitive.
Governance
Public schools must follow all federal, state and local laws in educating children. Such laws usually include specifics about funding, program development and curriculum.
Private schools are not subject to as many state and federal regulations as public schools. Since private schools are funded independently, they are not subject to the limitations of state education budgets and have more freedom in designing curriculum and instruction.
Curriculum
Public schools offer a general program, designed for all children, which usually includes math, English, reading, writing, science, history and physical education. In addition to these key subjects, many public schools offer programs in music and art. In a public school, the substance of what children learn is mandated by the state and learning is measured through state standardized tests.
NOTE: The charter school movement is picking up momentum in many states; these schools are public, but many offer specialized programs and smaller classes.
Private schools have the flexibility to create a specialized program for students. For example, private schools may use art or science in all classes, or take children on extended outdoor trips that blend lessons across the curriculum. Private schools can create their own curriculum and assessment systems, although many also choose to use standardized tests.
