Headlands Preparatory School (formerly Tilden Prep Marin) 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.
