Sero! is an award-winning, next-generation knowledge assessment platform based in concept mapping.

Many of today’s e-assessment systems don’t tackle the hard problems – they simply bring them online.

Item banks still rely on the same old assessment types, which are easy to grade but hard to write well. They also reward guessing and mostly just test the recognition or recall of discrete facts.

Writing assignments are only supported by uploading documents written in other systems. They take significant effort to score and require advanced writing skills for any diagnostic benefit.

The options have been limited: efficiency or deep assessment?

It’s time for deeper knowledge assessment, accelerated.


Sero! assesses knowledge and thinking by revealing the conceptual linkages that form the foundations of human knowledge and understanding.


Sero! enables rapid discovery of where and how a person’s knowledge is out-of-step or misconceived, making it useful for diagnosing, evaluating, and selecting.


While based in concept mapping, Sero! provides advanced capabilities that realize the benefits of the approach and enable broad-scale application and efficient deployment.

Concept mapping tasks tap cognitive abilities that are difficult to measure by other means.


Sero! provides automated support that accelerates the authoring, scoring, and analytics processes.


Sero! analytics enable quick and easy comparison of knowledge across time and peers.


Cloud deployment, xAPI readiness, and concept map importing ensure integration.

  • If my district subscribed, I’d definitely use Sero! | I’ve not seen anything like this. | Ingenious. As cool as I thought it would be. | Nifty - better holistic way to do assessment.

  • I liked it. I haven’t seen anything like this format. Usually just paper and pencil. I’d like to use it as an education officer. I can see this being really useful for testing someone’s knowledge. But as a learner, I’d probably do better on a Multiple Choice.

  • I just wanted to give some feedback on the concept map program! I really loved the program and thought it was easy to use and very self-explanatory. I think future students would have no problem figuring out the program, especially after the first time working through a map.
