CodeHSvsKhan Academy

CodeHS offers a complete ecosystem for teaching computer science, featuring flexible courses, professional development, and robust student progress tracking tools.

Khan Academy is a globally renowned, non-profit educational organization created with the singular mission of providing a free, world-class education for anyone, anywhere. Originally starting as a series of simple math tutorials uploaded to YouTube by founder Sal Khan, it has evolved into a massive, heavily structured learning platform utilized by millions of students, teachers, and parents worldwide. It is widely considered an essential supplementary tool for K-12 education, standardizing the way complex subjects are taught across different school districts. The platform is most famous for its incredible depth in mathematics, guiding students from fundamental early-childhood counting all the way through advanced college-level multivariable calculus and differential equations. However, it also features comprehensive courses in grammar, science, history, macroeconomics, and computer programming. The system utilizes highly effective "mastery learning," where students must score perfectly on short quizzes to prove they truly understand a concept before the software allows them to advance to the next level. **Pricing:** True to its founding mission, Khan Academy is 100% free. There are no subscription fees, no paywalled "premium" courses, and no advertisements anywhere on the site. The organization is funded entirely by philanthropic donations from individuals, massive grants from foundations (like the Bill & Melinda Gates Foundation), and corporate sponsorships.
