Your Participation in SEI Web Presence Tree Testing

Posted on by in

Can you help us test improvements to the SEI external web presence?

What is happening with the SEI's external web presence?

The SEI is improving the user experience of our external web presence. We have made improvements to the website information architecture based on previous tree testing and design research and need to validate the success of those improvements.

What is tree testing and how does it work?

Tree testing is an evaluative design research method to assess the organization and discoverability of content on a website. It is deployed using information architecture validation software called Treejack. This allows us to determine whether our changes to the information architecture have improved the user interface.

What exactly would I be doing?

When you access the test at, you will be guided through a set of tasks in the online tool Treejack, a product of Optimal Workshop.

What's the time commitment?

10-15 minutes

What's in it for me?

All participants who complete the test will be entered in a raffle to win a $50 Amazon gift card. You will be asked for your email address, which will be used to select two winning participants.

What do I have to do?

Take the test at by end of day Wednesday, July 27.
