Alison is a global online learning platform offering more than 6,000 free courses, certificates, and diplomas across categories ranging from business and IT to health, language, and personal development, serving more than 50 million learners worldwide. Courses are built by subject matter experts and partner institutions, broken into manageable modules with assessments at the end, and learners must score at least 80% to pass and unlock a certificate or diploma for the course they've completed. All course content itself is free to access and study at your own pace, while learners who want a downloadable or physical proof of completion, such as a digital, printed, or framed certificate, can purchase one once they finish a course. Alison's certificate courses are typically designed to be completed in under three hours, making them a fast way to fill a specific skills gap, while longer diploma tracks combine multiple certificate-level courses into more comprehensive learning paths for topics like IT administration, cloud computing, or healthcare training. The platform is CPD UK accredited, meaning many Alison certificates can count toward continuing professional development requirements, and learners can build a free, ATS-friendly resume directly on the platform using Alison's built-in resume builder. Alison also offers a Premium subscription that removes ads, unlocks certificate discounts, and adds priority support for frequent learners, along with a mobile app that supports offline course downloads for learning without an internet connection. Since its founding in 2007, more than 3.4 million learners have graduated from Alison's free courses, making it one of the most widely used free certification platforms for career upskilling.
