Concerto 5 is the newest version of the Concerto open source R-based Computer-Adaptive Testing platform, which is currently used in educational testing and in clinical trials. In our quest to make CAT accessible to all, the latest version uses flowchart nodes to connect different elements of a test, so that CAT test creation is an intuitive high-level process that does not require writing code.

A test creator might connect an Info Page node, to a Consent Page node, to a CAT node, to a Feedback node. And after uploading their items, their test is done.

This talk will show the new flowchart interface, and demonstrate the creation of a CAT test from scratch in less than 10 minutes.

Concerto 5 also includes a new Polytomous CAT node, so CATs with Likert items can be easily created in the flowchart interface. This node is currently used in depression and anxiety tests in a clinical trial.
