tilden prep is a unique, wasc-accredited, college-preparatory school for grades 6-12 that teaches u.c.-approved courses one-to-one and in small groups. we also use mastery learning, teaching students to 80% (b) or higher level of mastery before moving forward. this allows us to individualize the pace and teaching method to address a wide range of learning needs. from highly gifted students who find a regular classroom setting too limiting to students with learning differences who need a specialized teaching approach to shine academically, we are working with students to maximize both their learning and their self-confidence. our graduates are accepted at colleges throughout the country (see our college acceptances list), and the vast majority are able to maintain their ability to reach 80% or higher mastery in their college classes. we offer full-time enrollment, individual courses and tutoring services.
