Kaplan

Kaplan Test Prep is one of the oldest standardized-test preparation companies in the United States, founded in 1938 by Stanley H. Kaplan. It is a division of Kaplan, Inc., a wholly owned subsidiary of Graham Holdings Company since 1984, and sells courses, practice tests, and tutoring across more than 90 standardized exams, with affiliated brands including Manhattan Prep and Barron’s.

Kaplan offers prep in multiple formats: self-paced "On Demand" courses, scheduled "Live Online" classes, short intensive "Bootcamps," and one-on-one private tutoring. It covers major admissions and professional exams including the SAT, ACT, GRE, GMAT, LSAT, MCAT, TOEFL, and NCLEX. Courses bundle question banks, full-length practice tests, prep books, and analytics, taught by Kaplan’s own instructors.

Pricing varies widely by exam and format — for the SAT, On Demand is around $200, Live Online and Bootcamp around $800, and premium "Unlimited Prep" around $3,500 at full retail, with discounts common. Kaplan backs eligible programs with a "Higher Score Guarantee" and offers free practice tests and webinars. It suits students who want a long-established, structured brand with broad exam coverage and a score guarantee.
