Overview
Learnosity Build is an embeddable assessment engine for product and engineering teams building learning products. Its APIs handle the full assessment lifecycle (authoring, delivery, scoring, and reporting) inside your own product: you embed the engine rather than redirecting learners to a standalone testing portal. Build comes from Learnosity, the assessment infrastructure behind the world's leading learning platforms and educational publishers, serving more than 47 million learners worldwide. Teams that build assessment in-house typically spend 9 to 14 months and 5 to 8 engineers reaching a first production deploy; Build customers start authoring within an hour, reach a proof of concept in 1 to 3 weeks, and go live in 2 to 5 months, usually with one integration engineer alongside their existing product team. Stop waiting, start innovating. Authoring and content: Learnosity Build's AI-assisted authoring generates draft items from your source material and criteria for authors to review, edit, and approve, lifting content productivity up to 10x, and supports creating and managing assessment items in bulk. Engage learners with 50+ prebuilt question types, including drag-and-drop, hotspot, audio-response, advanced technology-enhanced items, and open-ended math, or build, configure, and style your own. A purpose-built math engine covers K-12 fractions through higher-ed calculus, with syntax-aware autoscoring and multimodal input that converts written responses into digital math. Item Bank Health Check audits your existing item bank in bulk: surfacing quality and accessibility issues, proposing fixes like AI-generated alt text for authors to approve, and mapping content to your chosen standards frameworks with automated coverage reporting. Delivery: every format, every device, fully yours. Render adaptive, branched, or linear assessments on any device and browser, with autosave, resume, and accessibility built into the assessment experience. Computer-adaptive testing (CAT) and rule-based branching are supported out of the box, with no player rebuild. White-label delivery keeps assessments inside your product and your brand, with feedback, hints, and a wide range of in-test tools. Grading and scoring: autoscoring comes standard across question types, from selected response to syntax-aware math. For written responses, Feedback Aide, Learnosity's embeddable agentic AI grading engine available with Build, scores short answers through extended essays with human-level accuracy and consistency, validated across subjects and levels, and returns rubric-aligned feedback for graders to review, revise, and approve. Analytics: turn every assessment interaction into an insight. 20+ out-of-the-box reports cover live progress, response analysis, and item analysis at any scale, from individual learners to international programs, or pull raw data through the Data API into your own warehouse. Enterprise trust comes standard. Learnosity delivers billions of questions and over a billion assessments a year on burst-ready, autoscaling AWS infrastructure with SLA-backed uptime, ready for opening weeks, exam weeks, every week. The platform is ISO 27001-certified and CSA STAR-registered; complies with GDPR, FERPA, and COPPA; and delivers WCAG 2.2 AA-accessible assessment experiences per item type, with accommodations engineered in, not bolted on. A VPAT is available on request. New releases ship every few weeks, so the engine stays current without your team maintaining it. Integration and developer experience: official SDKs for Node.js, PHP, Python, .NET, and Java drop straight into your stack, backed by documentation your engineers will actually want to use, a developer sandbox with live demos, and solution engineers paired with your team from first call to first ship. Integrate directly via API, support LTI 1.3 (Assignment and Grade Services) and LTI 1.1 grade passback with your LMS, and convert legacy QTI 2.1 item banks with Learnosity's open-source conversion library. Publishers, edtech companies, and institutions across K12, higher education, language learning, certification, and corporate training choose Build to ship assessment-rich products faster; audio playback and recorded-response question types support listening and speaking assessment. Standard (under 100K learners), Scale (under 350K), and Enterprise licenses include the option to add users as you grow, with AI authoring and scoring available as add-ons.

Robust Assessments, Best-in-Class Support, and Powerful Auto-Scoring
Reviewed on Oct 14, 2026
Review provided by G2
What do you like best about the product?
In our over 10 years of working with Learnosity, they have consistently been our absolute favorite organizational partner.
The assessment is extremely robust and feature filled. Our favorite features is the auto-scoring engine that can handle complex algebra and chemistry formulas.
Documentation is excellent, it's pretty much unheard of that we have to contact support to clarify or answer a question about normal usage.
When we do have to contact support about things like bugs or feature requests, our experience has been top-notch. Support is extremely responsive and knowledgeable. It's uncommon that we have to be referred to a higher level of support, usually the first person to respond is able to resolve our issue.
Overall, working with Learnosity has been an ideal experience for us.

What do you dislike about the product?
The authoring experience can be difficult to grasp for non-technical users. This is particularly true of math/chemistry auto-scoring, but even simpler question types like multiple-choice have a bewildering array of options available, and it's not always clear to non-technical users what they all do.
You can ameliorate this to some extent by limiting what options appear to your authors (and we do this), but that has its own downsides: If you remove a lot of options, sometimes authors will hit situations that they don't have the tools to resolve because those tools have been hidden.
So it's a tradeoff, simplicity vs. power. A pretty common tradeoff, but a real one nonetheless.

What problems is the product solving and how is that benefiting you?
We are a distance-learning organization. We use Learnosity for all of our online testing. It allows us to focus on test content without having to worry about how it's delivered, and reduces teacher workload by auto-scoring as much as possible.

White-Label, API-Driven Assessments with a Rock-Solid Item Bank
Reviewed on Jul 16, 2026
Review provided by G2
What do you like best about the product?
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.

What do you dislike about the product?
- Multi-environment content management is on you. There is no first-class promotion workflow between sandbox and production item banks, so we built our own sync and backfill tooling. It works, but it is custom code we have to own.
- Credential/environment wiring is easy to get wrong when you have multiple consumers across services - content that exists in one item bank but not another fails quietly at fetch time, and debugging that is on your side of the fence.
- The learning curve for the tagging and item/activity data model is real. Once it clicks it is powerful, but new engineers need time before they are productive.
- Documentation is generally good, but some Data API edge cases required trial and error.

What do you like best about the product?
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.
What do you dislike about the product?
Not much! We've had a few feature requests over the years (we've been working with Learnosity for 6-7 years), but they've been able to provide most of the features for us.
What problems is the product solving and how is that benefiting you?
We initially looked into developing our own test-taking platform for our LMS product but quickly realized how complicated it could become. After some quick research, we found Learnosity and were very impressed by the depth of their API. We quickly integrated it within our software suite and have been building with it ever since.
