The Texas Academy of Mathematics and Science (TAMS) is a two-year residential early entrance college program serving approximately 375 high school juniors and seniors at the University of North Texas. Students are admitted from every region of the state through a selective admissions process. TAMS is a member of the National Consortium for Specialized Secondary Schools of Mathematics, Science and Technology.

Early entrance to college, sometimes called early admission or early enrollment, is the practice of allowing high school students to be accelerated into college, one or more years before the traditional age of college entrance, and without obtaining a high school diploma. In some cases this is done individually. Often, however, it is done as part of a cohort acceleration program, in which many such students are accelerated into college together at the same time. These programs are usually targeted to gifted students, and may provide the students with a social support network and help in dealing with the adjustment.
