ASTI was planned and conceived as a small high school providing a college preparatory curriculum to students living in the San Francisco Bay Area.

ASTI ensures all students are involved in challenging learning experiences through its deliberate focus on rigorous and accelerated instruction in a well-defined academic course of study.

Through its concentration on writing and speaking, ASTI prepares its students with the skills necessary to promote college-level language production and content presentation.

Students are involved in a strand of interdisciplinary projects that align disparate subject areas: in this manner, ASTI teachers scaffold and structure student learning experiences to consciously aim at individual assignments and group projects of increasing difficulty and progressing complexity.

In 2016, ASTI was awarded its second consecutive six-year accreditation term from the Western Association of Schools and Colleges.
