Free online peer tutoring for middle school, high school, and college-prep students. Founded by Sal Khan (Khan Academy) as a separate nonprofit. Live small-group and 1:1 sessions over Zoom, run by volunteer tutors who pass a certification process. 100% free, no payment info collected.
Best for
- Students prepping for the SAT® (4-week bootcamps, official College Board partner as of 2026)
- Middle/high schoolers stuck on math homework (Pre-Algebra through Calculus and Statistics)
- Self-paced learners who want to catch up or get ahead in math over a school break
- Students who want a portfolio of math mastery certifications to show colleges
- Teen tutors who want volunteer hours and leadership experience — high schoolers can apply to tutor
How it works
- Sign up at schoolhouse.world — email and a username, no phone, no payment.
- Browse open sessions or bootcamps and reserve a spot. Sessions are live on Zoom, usually 5–10 learners with one trained peer tutor.
- For homework help, use Live Help for on-demand 1:1 sessions with a math-certified tutor.
- Optional: take a Schoolhouse Certification to prove mastery of a Khan Academy math unit. Passing certs unlocks the ability to tutor.
What to skip
- Don't expect a self-paced video course — Schoolhouse is live tutoring, not a Khan-Academy-style content library. Use Khan Academy itself for the lessons, then Schoolhouse for help.
- It's not a homework-answers service; tutors walk you through problems, they don't hand over solutions.
Cost and eligibility
Free worldwide. No age cap published, but the content and tutors are aimed at middle school through early college. Tutors must pass a certification + background process before running sessions.
