Frequently Asked Questions

You can visit the TAO Hub for more Community FAQs as well as our general FAQ page.

TAO Core is 100% open source. So, you can download and install the platform code for free.

You can deploy TAO Core on-premise through your own data centers. Or, you can use a third-party to host your platform. Whichever you choose, you’ll need to have someone with the following skills to set up your environment:

  • Software development expertise with the LAMP stack (PHP, Apache, Linux, MySQL, PostgreSQL)
  • Engineering and systems architecture expertise
  • Web front-end development (Javascript, XML, HTML, jQuery)
  • Hosting knowledge

If you don’t have someone with these skills readily available on your team you can work with a third-party. Or, leverage our managed services by upgrading to an Ignite, Pro or Enterprise package.

TAO Core is ideal for organizations who have the resources on hand to in-source a digital assessment solution.

To set yourself up for success, your team should have:

  • Software engineers with front and back-end web development skills
  • IT and Database architects
  • A dedicated hosting environment in place so you can deploy TAO Core yourself
  • Hosting and cloud knowledge for understanding delivery capacities

You have the flexibility to augment and extend the TAO Core source code with your own functionality. Keep in mind, changing the Core source code on your own, may interfere with compatibly as we release new platform upgrades.

Although any TAO user can read the platform’s source code, that doesn’t mean they have access to your personal data.

Whether you’re deploying proprietary or open source test creation software, you should always secure your environment through both organizational and IT administrative means to prevent unauthorized access to test content, student grades, etc.

Additionally, you should implement anti-cheating measures during test delivery. There is no distinction here between proprietary or open source software.

To keep your assessments secure, TAO encrypts data via HTTPS, and provides User Identification via encrypted passwords. It also supports back-office identification based on assigned roles and access rights.

We do not offer paid support packages with Client Services support for TAO Core. However, platform tutorial videos are available in our resource center and the TAO Hub for free.
