U.S. public schools

Free to attend and paid for with public money.

Public School

A free public school run by the local school district, teaching the regular academic program. It doesn't focus mainly on special education, career training, alternative education or a magnet theme. Most children go to the public school assigned to their home address, though many districts also allow transfers.

Charter School

A free public school that runs independently of the school district under a charter, a contract granted by the state or another authorized body. Charter schools have more freedom over curriculum, staffing and schedule, and must meet the goals in their charter to stay open. There's no tuition; when more students apply than there are seats, they usually admit by lottery.

Magnet School

A public school or program built around a special theme, such as science and math, the performing arts, gifted education or a foreign language, and designed to attract students from across the district. Many magnet schools were created to bring together students of different racial and ethnic backgrounds. Admission may be by lottery, application or test, depending on the school.

Career & Technical School

A public school that mainly prepares high-school-age students for skilled, technical and professional jobs, such as health care, construction, IT or culinary arts, often alongside a regular diploma. Some students attend full time; at regional centers they may split the day with their home high school. Government data calls these vocational schools.

Alternative School

A public school for students whose needs a regular school typically can't meet, offering nontraditional education. Examples include students catching up on credits, returning after a suspension or expulsion, or needing a smaller, more flexible setting. Some work as an extension of a regular school. Schola doesn't grade alternative schools: states judge them under separate rules, and ranking them against regular schools would mislead.

Special Education School

A public school focused mainly on students with disabilities, such as autism, intellectual disabilities, or hearing or visual impairments. It adapts its curriculum, materials and teaching for the students it serves. Students are usually placed there by their IEP team. Schola doesn't grade special-education schools, because their results can't be fairly compared with regular schools.

Run independently of government and mostly paid for by tuition.

Private School

A school run independently of the government and paid for mostly by tuition and donations. Private schools set their own admissions, curriculum and calendar, and can be religious or secular. They usually don't report state test results, so they don't get a Schola Grade.

Private Special Education School

A private school that mainly serves students with disabilities or learning differences. When a public school district can't provide the program a student needs, it sometimes places the student at a private special-education school and pays for it.

Why some schools have no grade

A Schola Grade needs official test results. Private schools usually don't report them. Alternative and special-education schools aren't graded on purpose: they serve students in very different circumstances, and ranking them against regular schools would mislead. How Schola Grades work.
