SIL’s tuition structure and philosophy.

Tuition Structure

At SIL, tuition reflects the personalized and flexible nature of our program. Because every student’s needs are unique, we structure tuition around instructional time to ensure you’re only paying for the education you need. We offer a base flat-rate tuition, payable in installments, which covers a set amount of instruction each semester; additional hourly tuition applies only if a student requires more time beyond that base. Unlike other 1:1 schools in the Bay Area, our mastery-learning model does not impose minimum course hours. Once a student demonstrates understanding and mastery of the material through formal assessment, the course is considered complete. This approach makes it possible to tailor the pace, depth, and duration of instruction to each learner.

Our tuition rates support the high-quality instruction provided by our faculty, whose average tenure exceeds eight years. Since every student’s path is individualized, overall tuition varies from semester to semester.

While most of our classes are one-to-one, we also offer small group sessions at a reduced tuition rate per student. These groups typically form when students enroll with a friend or classmate pursuing the same course. Because of our rolling admissions and highly flexible scheduling, group class arrangements require additional coordination.

In addition to year-round one-to-one and small group classes, SIL also offers Summer Programs—both for-credit and fun enrichment courses.

Annual Tuition Ranges

We understand that families value clarity around long-term costs. While tuition is based on instructional hours, we provide estimated yearly ranges to help with planning. Because each student’s educational journey is unique, total tuition varies depending on grade level, course load, and pace of learning. Many students progress more quickly through material in our individualized model, though some may benefit from additional instructional support.

For example, a senior transferring to SIL with most graduation requirements already fulfilled will incur significantly lower tuition than a freshman entering full-time high school. A dually enrolled junior splitting time between SIL and another school, or a 7th/8th grader accelerating into high school coursework, will likewise have reduced tuition compared to a full-time sophomore completing a broad course load for college applications.
