Operationalizing CAST-Universal Design for Learning for Individuals with Severe Disabilities: The Lifespace Access -Learner Resources Model
The UDL & LRM Connection
The Lifespace Access Learner Resources Model (LRM) and UDL 3.0 both prioritize learner agency and identity. While UDL 3.0 (released in 2026) expands into emotional capacity and belonging, the LRM has provided a functional framework for these emotional resource dimensions for individuals with severe disabilities since 1993.
UDL, We have been here waiting for you since 1993.
The Neuroscientific "Fingerprint"
In the early 1990s, Dr. David Rose, the neuroscientist who founded CAST and pioneered Universal Design for Learning (UDL), used the analogy of a fingerprint to understand learner variability. He wanted to map the uniqueness of what each individual brings to a learning activity. His early work focused on how three networks in the human brain (Affective, Recognition, Strategic) interacted in the process of learning. UDL proved to be a powerful tool for examining the dynamics of learning and for guiding the development of instructional activities and materials.
Over the ensuing 30-plus years Dr. Rose’s and CAST’s appreciation of all dimensions that truly impact access to learning and participation has expanded. The widening of the UDL model reflects that recognition. Expansion of the UDL model was inevitable when its application left the academic realm and started making contact with the real world.
UDL meets World
In one of my favorite anecdotes, that was documented in the 2014 Ed. magazine article,
“How Universal Design for Learning Became a Big Idea.”, Dr. Rose recounts the early days working with his longtime colleague Dr. Anne Meyer. (It may have been an early excursion into the territory where Lifespace Access was born.)
“ Early on, the team had dramatic success with a young boy named Matt who had cerebral palsy and could only communicate by blinking his eyes and opening and closing his mouth. The school system assumed he was profoundly mentally disabled and was going to pay to have him institutionalized. But his mother believed her son was intelligent — he just couldn’t communicate it.
The team decided to teach him Morse code and gave him a switch connected to a computer that he could direct with his chin. “He learned Morse code in about 10 minutes,” Rose remembered. Then they taught him the alphabet.
Given that access, the first message Matt typed out to his mother was, “I love you.”
Eventually, Meyer digitized some books for him, setting up a program where he could have the book read aloud and could turn pages by clicking with his chin. “He was so excited to be enabled in this way. Sweat was just pouring off him as he was reading.”
Matt’s was a very dramatic case, but it showed Rose and his colleagues how powerful an intervention computers could be. “That kind of transformation was what we were after — something that could make everything change,” Rose says in the article, ”CAST wanted the system to be elastic enough to fit all the kids.” UDL has grown to reflect that goal.
The Foundation of the Universal Design for Learning
UDL framework is built upon the foundation of three principles that reflect Dr. Rose’s neuropsychological background. Those core principles: Engagement, Representation, and Action & Expression.
To successfully engage these Networks in the Learning Process it is critical to provide:
- Multiple Means of Engagement
- Multiple Means of Representation
- Multiple Means of Action & Expression
The UDL describes how the application each of these Networks to the Learning Process requires:
- Access - Interests & Identities, Perception, and Interaction Needs & Preferences
- Support - Effort & Persistence, Language & Symbols, and Multiple Tools & Methods
- Synthesis - Emotional Capacity, Building Knowledge, and Intentional Use
What's new - UDL 3.0 (2026)
The truly exciting expansion of the UDL reflected in the 3.0, 2026, update is a critical new dimension focused on Identity and the “Who” of learning.
This is a new dimension that a learner’s intersecting identities (culture, race, gender, etc.) directly impact how they perceive and engage with learning. In this important expansion of their model CAST and UDL are now acknowledging the importance of nurturing things like “Joy” and “Play” and feelings like Belonging and Empathy.
Beyond "Expert Learner" to "Individual Agency"
The definition of Lifespace Access: Active participation, with choice and control, in the activities that occur where we live, learn, work and play.”
It has served as the foundation of our efforts since 1993. It goes beyond trying to create an “Expert Learner” to a place where every Individual has “Agency” within their Lifespace.
OUR FOUNDATION
The Learner Resources Model
Physical Resources
Abilities and functioning mediated by the Individual’s general health, motor and sensory systems.
Cognitive Resources
Abilities and functioning mediated by the Individual’s cognitive capacities and mental processes.
Origins of Two Models
Dr. Rose and CAST had a very different point of origin than Lifespace Access and the LRM. CAST & UDL started in the academic atmosphere of Harvard. Neuropsychology labs and lecture halls. Research papers and professional publications.
CAST was concerned with the concept of learning.
Lifespace Access Profiles started in classrooms serving students with profound disabilities. In an era when deinstitutionalization and the use of assistive technology were emerging ideas. When assessment and planning tools to work with these populations were nonexistent.
In these classrooms there were no assumptions about perception, the understanding of cause-and-effect, or purposeful movement at any body site.
Lifespace Access Fingerprints
Acknowledgement and Thanks
I want to acknowledge the influence of J. P. Guilford’s works, the Structure of Intellect (SI) model on my concept of human capacity for learning and the factors involved in the process.
It was originally published in the journal Psychological Bulletin in a landmark paper titled “The Structure of Intellect” (Vol. 53, No. 4, pp. 267–293, July 1956.) The SI was arguably the first “elastic” system designed to fit the learner. In UDL terms Guilford may have been the architect of the 150-Factor “Fingerprint”.
