The Texas Academy of Mathematics and Science (TAMS) is a publicly financed, residential early college entrance institute at the University of North Texas at Denton. Created in 1987, TAMS enables high-achieving students planning STEM careers to complete their last 2 years of high school simultaneously with their first 2 years of college. Admission is selective, and students pay no tuition or book costs. Students must complete a rigorous curriculum of biology, chemistry, physics, mathematics, and humanities. The academy offers intramural athletics, a variety of clubs and organizations, and mentor-guided research opportunities that can lead to prestigious awards and scholarships. Graduates earn a high school diploma and at least 57 transferable college credits--enough to enter many universities 2 years advanced. Now in its third decade, the academy continues to help expand the supply of skilled domestic mathematicians, engineers, and scientists. (Contains 2 figures and 6 tables.)
