THE NATIONAL RESEARCH & TRAINING CENTER ON BLINDNESS & LOW VISION (NRTC)
Kendra FarrowResearch and Training Associate
The NRTC is the only U.S. Department of Education-funded center focused on employment outcomes of persons with blindness or low vision.
We plan to utilize data and information from NRTC to support the Low-Vision Audio Planner.
