Study technology, or study tech, is a methodology for learning developed by L. Ron Hubbard, founder of the Church of Scientology. Hubbard's "Study Tech" is used by Church of Scientology members as part of their training, and is also promoted outside the church by a church-affiliated corporation known as Applied Scholastics, which presents study tech as a universally applicable method to enhance the comprehension of any student, studying any topic.

Study tech primarily describes and addresses what it calls "the three barriers to study"; misunderstood words (MUs), lack of mass, and too steep a gradient. These "barriers" are addressed in study tech by finding and "clearing" (i.e. fully understanding) misunderstood words as they are encountered, obtaining the actual physical presence ("mass") of subject, and by making sure the student is not proceeding through course materials too quickly (without full understanding of the previous concepts).

Though both Applied Scholastics and the Church of Scientology say that Hubbard's study tech is tremendously effective, practically no supporting data has appeared in educational journals or other third-party publications. The study tech materials have gained little acceptance among public school administrators or scholars of educational theory.

Hubbard wrote that study tech is part of the "Tech of Scientology ," and stated in a policy letter the "Study Tech is our primary bridge to Society."
