Khan Lab School
by Khan Lab School (website )
An innovative, mastery-based private school founded by Sal Khan, offering both physical and full-time online enrollment options.
Best Fit For
Self-driven students who want to move through curriculum at their own pace and prefer project-based learning over traditional testing.
Not Recommended For
Families looking for a low-cost homeschool supplement or students who require a highly rigid, traditional classroom structure to stay focused.
What Reviewers Say
Reviewers consistently describe Khan Lab School as a transformative environment for self-motivated students who thrive on autonomy. The mastery-based approach—where students must demonstrate competency before moving on—is the most praised feature (Niche, Private School Review). However, the school's 'lab' nature means it is constantly iterating, which some parents find leads to organizational flux and a lack of traditional structure (GreatSchools, Yelp). While the online program is highly rigorous and community-focused, the primary trade-off discussed is the high tuition cost, which positions it as a premium private school rather than a budget-friendly homeschool resource. Critics occasionally note that the transition from a 'playful lab' to the academic pressures of high school can be abrupt.
How It Works
For families using the online program, the student's day is split between independent 'Mastery' time and live, group 'Inquiry' sessions. The child spends roughly 90 to 120 minutes each morning working through personalized goals on the Khan Academy platform, while the parent acts as a facilitator who monitors a digital dashboard to ensure progress. Afternoons involve live, teacher-led seminars or collaborative projects where the child interacts with peers over a video call to solve real-world problems. The parent does not need to grade assignments or prep lessons, as the school provides the curriculum and the platform handles the tracking of competencies.
Switching to This?
Khan Lab School does not use a traditional grade-level placement test; instead, they utilize Khan Academy’s internal diagnostics and teacher assessments to place students based on their actual skill level in each subject. Families should be prepared for an intake process that includes a student interview and a review of previous work to ensure the child is a good fit for a self-directed environment. While students can technically start at any time if there is an opening, most families find it easier to join at the beginning of a term to align with the start of new collaborative projects. If you are switching from a traditional textbook-based program, expect an adjustment period where the student learns to manage their own time and set daily goals without a rigid hourly bell schedule.

Reviews We Consulted
Applauds the mastery-based curriculum for producing exceptionally strong math students but notes the "experimental" atmosphere can feel unstructured to some families.
"Khan Lab School K–12 stands out for its EXTREMELY ACADEMIC environment and mastery-based learning. Students don't just learn math—we are CRAZY GOOD AT MATH... Many advance far beyond grade level, building deep understanding and real problem-solving skills."
Criticizes the school's lack of transparency regarding daily student progress and warns that many staff members lack traditional teaching experience.
"I recently learned that about half of KLS teachers have no prior teaching experience; compared to only 4% of Landels teachers with 3 years or less. Imagine being a new teacher at a school where half your peers are just as new AND are trying to invent a new curriculum!"
A critical perspective suggesting the school has abandoned many of its founding "lab" concepts in favor of a more traditional, age-based instructional model for most subjects.
"One important thing for prospective families to know is that of the ideas presented in Sal Khan’s 'The One World Schoolhouse,' very few are still practiced at KLS... At this time KLS operates much more like a good traditional school than it does as a reflection of its founding ideals."
A student perspective highlighting a shift toward a more conventional education model, claiming the school's current reality no longer matches its "revolutionary" marketing.
"For the past 2 years, new leadership has been pushing a more conventional education model for ease and convenience. Khan Lab School was once revolutionary, but now it is overrated."
Profiles a parent who values the school for providing an independent, experience-based learning path that escapes the "chunked" programming of traditional institutions.
"I hate the term home schooling because it’s based on location. It’s not really about having them at home. What we’re trying to do is build an independent path. It’s not about the schooling, it’s about experiences."
Provides an academic observation of how the school replaces traditional grade levels with "Independence Levels" and uses digital trackers to manage student progress.
"Because KLS groups children by how well they demonstrate knowledge and skills in various areas–Independence Levels 1-6–rather than being first or third graders, the staff has developed rubrics or ways of knowing how well students are doing in a subject or skill."
Commends the school's ability to rethink the educational system and its high level of preparedness for digital and remote learning transitions.
"They haven’t missed a beat with the transition to remote learning, but given Khan’s attempts to rethink our whole educational system, you’d hope that’d be the case."

How This Compares
Parents frequently compare Khan Lab School to Sora Schools, as both offer a full-time virtual experience, but KLS is more strictly built around the Khan Academy 'Mastery' software while Sora is more fluid and student-led. When weighed against Prisma, KLS provides a more data-driven academic map of progress, whereas Prisma focuses more on badges and workshop-style learning. Compared to using the free Khan Academy platform alone, the Lab School adds the critical human elements of live teachers, peer seminars, and a social community that many homeschoolers find missing in self-paced digital tools. Families looking at Time4Learning often find KLS to be the higher-rigor, more expensive 'premium' choice that offers real-time interaction, whereas Time4Learning is a largely automated, pre-recorded experience. Finally, when compared to Moving Beyond the Page, KLS is significantly more screen-dependent and digital-first, making it better for tech-savvy students who prefer online feedback over physical, paper-based project kits.
