The Open-Source Online Adaptive Testing Platform
Now anyone can create online assessments, from simple surveys to sophisticated IRT-based computer-adaptive tests (CATs) with textual and graphical feedback. Concerto uses the powerful R statistical programming language, which you can use to do any calculations your test requires. Concerto is free for academic and commercial use. There are no set-up costs, no hidden licence fees and no limitations.
