URLEND was initially funded in 2001 as the first LEND program with long-term trainees across multiple states. It was established and is maintained as a partnership between the University of Utah School of Medicine, Department of Pediatrics and Utah State University, Institute for Disability Research, Policy, and Practice. In 2018, Utah State University added the newly founded Sorenson Legacy Foundation Center for Clinical Excellence as a partner.
Additional partners are found in each state through the University Centers for Excellence in Developmental Disabilities Education, Research and Service (UCEDD) and Family to Family agencies, along with Brigham Young University and Idaho State University. There are almost 40 URLEND faculty and staff throughout these states, including self-advocates, family members, and professionals with autism expertise.
