Using AI to Create Image Descriptions in High Stakes Testing

Date & Time
Thursday, March 21, 2024 - 11:20 AM PDT  
Elite 1-3  
Assessment content containing images or graphics requires image descriptions for screen reader users. Construct measurement constraints around image descriptions poses a great challenge for designers of high stakes assessment whose aim is to provide an equitable and accessible test-taking experience to all its test takers; where there are elements of graphics that can be described and still preserve construct, users should have access to consistent descriptions. Without industry-wide standardized language for image descriptions, manual scripting for image descriptions is labor intensive, has an increased risk for error, and is not scalable. Working with Continual Engine and their Invicta™ product, ACT Inc. piloted a solution for automating image descriptions in its assessment content to generate consistent output with scalable results. Continual Engine designed and developed Invicta™, a generative artificial intelligence solution that uses sophisticated algorithms to accurately create detailed descriptions for graphics and images, which can be customized and edited to meet assessment requirements. In this session, ACT, Inc. and Continual Engine representatives will give an overview of the pilot, demonstrate the Invicta™ product used, review essential lessons learned throughout the pilot, and discuss possible future steps toward evolving an industry standard for image descriptions in high-stakes assessment.
