Brightworks: Parent Guide to a Project-Based, Maker-Centered K-12 School

Brightworks is a private, nonprofit K-12 independent school in San Francisco, founded in 2011 by Gever Tulley as an outgrowth of Tinkering School, a summer camp he started in 2005 ³¹⁴. The school serves students from kindergarten through 12th grade at a single campus in the Presidio of San Francisco, a national park site, under a partnership with the Presidio Trust¹⁷. Brightworks is operated by the Institute for Applied Tinkering (IAT), a nonprofit that also runs Tinkering School, the Curious Educators Division (CED), and an Innovation Lab¹⁵.

The school departs from conventional schooling in several key respects. It replaces traditional grades and tests with a project-based framework called "The Arc," organizes students into mixed-age "bands" rather than single-grade classrooms, and calls its teachers "collaborators" ²⁴¹⁶. Students use real tools to pursue interest-driven projects, and the high school program, Studio Brightworks, uses competency-based assessment through the Mastery Transcript Consortium instead of letter-grade transcripts ⁵¹⁹.

What it is

Brightworks is a single-campus, in-person K-12 independent school operated by the Institute for Applied Tinkering, a nonprofit organization¹⁴. The school opened in 2011 with 19 students in a warehouse space, growing out of the tinkering philosophy that Gever Tulley developed through Tinkering School, which he founded in 2005 ³¹⁴. Tulley, a self-taught computer scientist with no formal education background, has spoken at TED twice and authored the book "Fifty Dangerous Things (You Should Let Your Children Do)" ¹⁵. A 2011 KQED article identified Bryan Welch, director of A Curious Summer workshops, as a co-founder ¹³.

The school currently operates within the Presidio of San Francisco under a partnership with the Presidio Trust¹⁷. It previously operated at 360 9th Avenue in San Francisco before relocating to the Presidio. The California Department of Education lists the school as active with an open date of October 3, 2011 ¹¹. The school has been featured in publications including The New York Times, NPR, and The Atlantic, and was the subject of a 2017 NAIS case study, according to the school's own press page ²²¹. The school also claims to have been named one of the "13 Most Innovative Schools in the World," though the originating publication is not specified on its website ².

Educational model

Brightworks' central pedagogical framework is "The Arc," a cycle of two to three immersive thematic explorations per school year ²⁴. Each arc progresses through three phases: Exploration, in which students collectively investigate a central theme; Expression, in which students design and execute individual or small-group projects; and Exposition, in which students present their work to the community and external audiences ⁴⁵. The school describes this approach as emphasizing depth over breadth, integrating skill development within real-world contexts rather than through discrete subject-area instruction ²⁵.

Teachers are called "collaborators," reflecting the school's philosophy that educators work alongside students rather than transmit knowledge to them ²¹⁸. Students are organized into mixed-age groups called "bands" rather than traditional single-grade classrooms ¹⁶. The school states that it draws inspiration from the Common Core, Next Generation Science Standards, Learning for Justice, and ISTE standards when designing its competency framework, though it does not use traditional grading ⁵. Social-emotional learning, restorative justice practices, and an explicitly antiracist and inclusive community orientation are described as central to the program ¹².

Student experience

The school day combines group project work, independent study, outdoor exploration in the Presidio, field trips throughout San Francisco, and interactions with visiting experts and community partners ¹². Students use real tools and materials to engage with authentic problems rather than simulated exercises ²¹⁸. The Presidio location provides access to redwoods, creeks, and natural spaces that extend the classroom outdoors ¹.

For high school students, the program operates as "Studio Brightworks," a small, personalized program where students pursue individualized pathways that may include internships, concurrent college enrollment, and interdisciplinary project work ⁵¹⁹. The high school day includes group subject study, independent project time, community service, outdoor experiences, and field trips ⁵.

Enrollment figures vary across sources and years. The NCES Private School Universe Survey reported 112 students for 2021-2022 with 15.6 full-time-equivalent teachers and a student-teacher ratio of 7.2 ¹⁰. NAIS lists enrollment in the 0-100 range ⁹.

Curriculum, assessment, and progression

Brightworks does not use traditional letter grades or standardized tests ⁵¹⁶. Students build portfolios of project work, and the high school partners with the Mastery Transcript Consortium to produce competency- and portfolio-based transcripts ⁵. The school identifies three graduate competency areas: Communication and Self-Expression, Social-Emotional and Community Awareness, and Self-Directed Learning ⁵. Students earn competency credits for interdisciplinary work compiled into portfolio transcripts that are designed to be understood by college admissions offices ⁵.

The school states that its graduates have transitioned to traditional San Francisco independent high schools such as Urban, Bay, Drew, Lick, and SOTA, as well as specialized programs like the Culinary Institute, and four-year universities ¹. These outcomes are school-reported.

Public, charter, private, nonprofit, program, network, or platform status

Brightworks is a private, nonprofit, nonsectarian independent school registered with the California Department of Education¹¹. It is operated by the Institute for Applied Tinkering (IAT), which the verified block identifies as the parent organization. IAT also operates three sibling programs: Tinkering School, the Curious Educators Division (CED), and the Innovation Lab¹⁵. The school holds a membership with the National Association of Independent Schools (NAIS) and was the subject of a 2017 NAIS case study⁹²¹. No formal accreditation is listed in the verified block, and a 2014 news article described the school as "not-yet accredited" ¹⁶.

A disputed leadership matter exists. A Summer 2024 board post named Sean Hamer as the new Head of School, while the current staff page and a subsequent announcement name Michlene Cotter as Head of School²⁰²³²⁴. The school's staff page lists Michlene Cotter as Head of School and Gever Tulley as Founder ²⁰.

Regarding funding, the verified block identifies the school's funding stage as nonprofit with no verified outside equity investors. A Tracxn aggregator profile claims institutional investors and funding rounds, but no tier-1 source corroborates outside equity investors; this claim is unverified.

Locations and availability

Brightworks operates a single campus at 682 Schofield Road in the Presidio of San Francisco, CA 94129¹⁷. The school offers no virtual or online programming. It previously operated at 360 9th Avenue in San Francisco before relocating to the Presidio. No additional, planned, paused, or closed campuses are listed on the school's website.

Tuition, admissions, and eligibility

Tuition for the 2025-26 school year is $43,853, which the school states includes all school and project supplies, field trips, expert visits, technology, yearbooks, and community meals⁶. The school reports that it assists approximately 47% of families with need-based tuition grants ranging from 10% to 100% of total tuition ⁶. Tuition assistance applications are processed through the third-party platform Clarity, and the school partners with the BASIC Fund to support K-8 applicants from lower-income families⁶⁸. A ten-payment plan is available and includes tuition insurance ⁶.

Admissions are application-based, conducted through the Ravenna platform ⁷⁸. Applications for priority consideration are due in January, with rolling admissions afterward until spots are filled ⁷⁸. The process includes a family application, teacher evaluations, transcript requests, a parent conversation via Zoom, and a student visit ⁷. For K-8 admission, students must be at least 5 years old by September 1 ⁸.

Credits, transcripts, diplomas, and accreditation

• Brightworks does not issue traditional letter-grade transcripts.
• High school students build Mastery Transcripts through the Mastery Transcript Consortium, which presents competency-based evidence of learning to colleges and employers ⁵.
• The school states that these transcripts are designed to be understood by college admissions offices and that graduates have been accepted to four-year universities ⁵¹.
• No formal accreditation is listed in the verified block.
• The school holds NAIS membership, which is distinct from NAIS accreditation⁹.
• Families should note that the absence of formal accreditation may affect transcript recognition at some institutions.

Evidence and outcomes

Outcome data for Brightworks is primarily school-reported. The school states that graduates have gone on to independent high schools, specialized programs, and four-year universities ¹. Niche, a third-party school review platform, reports a 100% graduation rate and states that 55% of graduates attend four-year colleges, but these figures are based on user-submitted data and the school's small enrollment makes such statistics volatile ²². The NCES reports enrollment and staffing data from the 2021-2022 Private School Universe Survey, showing 112 students and 15.6 FTE teachers ¹⁰. No standardized test score data is available, as the school does not administer standardized tests.

Best fit

Brightworks may be a fit for families seeking a small, project-based learning environment where students drive their own inquiry and use real tools to create tangible work. The mixed-age, collaborative structure and emphasis on social-emotional learning may suit children who thrive with autonomy and hands-on engagement. The high school's Mastery Transcript approach may appeal to families looking for an alternative to traditional GPA-based assessment. Families should consider whether their child is comfortable with unstructured project work, limited formal assessment, and a small school community, and whether the tuition cost and the absence of formal accreditation align with their long-term educational goals.

Questions parents should ask

• How does the school document and communicate academic progress in the absence of grades and standardized tests, and how do receiving schools and colleges evaluate Brightworks transcripts?
• What is the current leadership structure, given the disputed Head of School identification, and how does leadership turnover affect program continuity?
• What specific college and post-graduation outcomes can the school document for recent graduates, and how does the Mastery Transcript perform in college admissions?
• How does the school support students who may need additional academic structure or specialized learning support?
• What is the current enrollment and class size, and how does the small school community affect peer social dynamics across age groups?
