TAO

TAO started as a research concept in 2002 at the Luxembourg Institute for Science and Technology and the University of Luxembourg, with a first prototype in 2004, according to the company's history page. The software is now maintained by Open Assessment Technologies S.A., whose terms of use are governed by Luxembourg law.

Proctoring is not the core of the product. TAO lists proctoring among its partner integrations, so a buyer pairs the platform with a specialist for camera supervision.

Open source and standards

The Community Edition is free to install and customise. The code in the vendor's own GitHub organisation, oat-sa, carries the GNU GPL v2 licence. TAO says it supports the QTI and LTI standards, which is the main argument for lower lock-in.

Platform scope

Components cover authoring, high-stakes delivery with session monitoring and lockdown control, scoring with grader routing, and psychometric reporting. The site describes products ranging from open source to a tiered turn-key package to a customised enterprise deployment for national-scale assessment.

Legal entities

The contact page lists the Luxembourg company at Capellen, a US corporation in Delaware and a Madrid office. The privacy policy names the Luxembourg company as controller. A US-based buyer may sign with the US entity, which this review has not checked.

Limitations to Consider

There is no native video proctoring, so the platform alone does not replace Proctorio. Running the Community Edition means your own hosting, security patching and support. Cloud pricing is by tier and the amounts could not be read, and the hosting region on AWS and Google Cloud is not stated on the pages checked.

Who Should Use TAO

Public bodies, universities and test publishers that value open standards and may want to host the platform themselves, and that will add a proctoring partner where needed.
