all children. The American camps developed from a very different cultural root. Educational camps In the United States, there are numerous models of camp with an educational focus that cater to students of differing ages and academic interest. College credit courses Some camps offer students the opportunity to explore a pre-college experience. Typically, students entering grades 10 through 12 stay in the college dormitories and attend summer classes run by college faculty. At the successful completion of a summer program, course credits are awarded, which in turn are accepted by most tertiary institutions. Typically, colleges in the United States and Canada offer these programs, as it serves as an introduction to students to entice them to attend the college as full-time students based upon a memorable summer experience. Non-college credit courses Some camps, such as CTY and Duke TIP, are focused primarily on education or on educational-related activities, such as debate, history, or journalism. These camps are often run by colleges or universities, and are usually for children in junior or senior high school. Instruction in debate and speech is also available for middle school students and incoming high school students all over the country. Educational summer camps are different from summer schools as the summer camps often are not offered for school credit, and often have a significant focus on non-academic activities. Students for these programs are often invited or recruited. Many of these camps, such as Canada/USA Mathcamp and SSP, focus on a specific subject, such as mathematics or astronomy. These camps tend to have selective application processes involving problem solving or an essay about the applicant's interest in the subject. Academic adventure camps These provide high school students with the opportunity to study academic topics on a summer adventure travel program, typically in the wilderness or a foreign country. Many include community service as a component of the course. Others also offer college credit with the successful completion of the program.

These camp programs often outsource their SAT component from test preparation companies like The Princeton Review or Kaplan who provide the teachers and resources.
