We run a fully white-label online homeschooling platform, and Learnosity is the assessment and content engine underneath it. Our students and parents never see Learnosity - quizzes, lessons and interactive activities render natively inside our own LMS with our branding, our navigation and our design system. That white-label capability was the deciding factor for us: it behaves like infrastructure, not a bolted-on third-party product. The item bank is the other standout. We manage thousands of lessons and quiz items tagged by grade, term, subject and week, and that tagging model maps cleanly onto a structured curriculum. Our content team authors and publishes items, our internal admin tools drive publish/republish and versioning workflows on top of the APIs, and we sync content between sandbox and production item banks as part of our release process. For a curriculum with a large, constantly-edited content surface, that authoring-to-publish pipeline has held up well. Everything we do with it is API-driven. The Data API covers items, questions, activities, tags and sessions, so we have been able to automate almost everything: entitlement-aware quiz eligibility, session save/complete flows, score retrieval for parent reporting, automated quiz generation from item pools, and even fetching lesson content programmatically to power downstream features (we build text-to-speech audio from lesson content pulled via the API). The signed request model (consumer key/secret + domain) is simple to implement, the regional endpoints keep latency low for us in Australia, and the LTS versioning scheme means upgrades are predictable rather than surprise breakages. Reliability has been strong. Assessment sessions, answer persistence and completion events are the parts of our platform we can least afford to lose, and Learnosity has been a stable layer there.

Their API is truly impressive. The UI is simple enough that classroom teachers can build great tests for their students, but advanced enough to build district wide benchmarks.
