Headlands Preparatory School

What makes this school special

Every academic class is one teacher and one student, on a mastery model: 80% or better before moving on, reteach and reassess until it sticks
The Marin sibling of Tilden Prep (it began as Tilden Prep Marin), now its own school on Bridgeway in downtown Sausalito — a ferry ride from the Ferry Building
A deep catalog for a tiny school: UC-approved courses and seven languages, from American Sign Language to Japanese
Serves the students other schools schedule around: gifted and twice-exceptional students, learning differences, athletes and performers, and students who need school to flex around health
Part-time enrollment lets a student stay at their own school and take one or two courses here

The application

Enrollment is year-round: an informational call, a tour, and an interview with the Director or Head of School, then registration materials and a scheduling meeting that designs the student's actual program. Tuition follows the schedule that meeting builds — the school publishes no sticker price and prices each student's plan, so cost questions go straight to the school.

Application requirements

Informational call, campus tour, and an interview with the Director or Head of School
Registration materials — transcripts, immunizations, any IEP/504 or evaluations
Registration deposit, then a scheduling meeting to build the student's program
