Cognitive Disability Frame of Reference: Allen Cognitive Levels Explained
Allen's cognitive disability frame of reference: the 6 cognitive levels, ACLS and RTI assessments, how to adapt tasks at each level, a case and a quiz.
Why can one person with dementia still cook a familiar recipe while another can’t make a sandwich? Why does someone recovering from psychosis manage their morning routine but struggle with a new bus route? Occupational therapist Claudia Allen created the cognitive disability frame of reference to answer questions like these, linking a person’s cognitive level to how they function in daily life.

What is the cognitive disability frame of reference?
Claudia Allen developed this frame of reference while working in psychiatry, and first published it in 1985. It assumes that a person’s ability to process information, pay attention, learn and solve problems sets limits on how they perform tasks. It also assumes that function can be maximised by matching the task and environment to the person’s level.
Key assumptions
- Cognitive abilities can be described in levels, from automatic to planned actions.
- Each level brings predictable strengths and limits in task performance.
- In many conditions, especially progressive ones, the level itself may not change much with therapy.
- People function best, and most safely, when tasks and environments are adapted to their level.
- Caregivers can be taught to provide the right amount of help.
The Allen cognitive levels chart
Most independent ↑
-
Level 6: Planned actions6
Plans ahead, anticipates problems and thinks of consequences. Independent.
-
Level 5: Exploratory actions5
Learns by trial and error; notices surface details; may miss hidden hazards or long-term consequences.
-
Level 4: Goal-directed activity4
Follows familiar routines using visible cues; struggles with new problems and things out of sight.
-
Level 3: Manual actions3
Uses hands on familiar objects repetitively; needs step-by-step cueing; no sense of task goal.
-
Level 2: Postural actions2
Moves the body with help; follows simple one-step movements; needs help with most self-care.
-
Level 1: Automatic actions1
Responds mainly to basic sensations; needs total care.
Most support needed
Each level is divided into modes in decimal steps (e.g. 4.0, 4.2, 4.4, 4.6, 4.8).
What each level means for daily life
| Level | What the person can usually do | Support often needed |
|---|---|---|
| 6 | Manage complex and new tasks, plan ahead | None related to cognition |
| 5 | Learn new tasks by trying them; live in the community | Help anticipating safety issues, finances or new complex decisions |
| 4 | Familiar routines and simple tasks with visible cues | Daily check-ins; help with money, medication and new problems |
| 3 | Repetitive actions with familiar objects, like wiping a table or folding | Constant supervision and step-by-step cueing; a safe environment |
| 2 | Simple movements with assistance, e.g. standing to be dressed | Help with most self-care; 24-hour care |
| 1 | Basic responses such as swallowing or turning to a sound | Total care |
General guide only. Decisions about safety and living arrangements need a full assessment.
How cognitive level is assessed
| Tool | What it involves |
|---|---|
| Allen Cognitive Level Screen (ACLS) | Copying leather-lacing stitches of increasing complexity: running stitch, whip stitch, single cordovan stitch. Scores range from 3.0 to 5.8. |
| Large Allen Cognitive Level Screen (LACLS) | A larger version for people with visual or fine motor difficulties |
| Allen Diagnostic Module (ADM) | Standardised craft projects graded to different levels |
| Routine Task Inventory (RTI-E) | Observation or report of performance in daily tasks |
| Cognitive Performance Test (CPT) | Standardised functional tasks, such as dressing and shopping, linked to Allen levels |
Intervention: adapting to the level
| Level | How to set up a task (example: making a drink) |
|---|---|
| 5 | Teach a new method by demonstration and practice; point out safety risks (e.g. hot kettle) |
| 4 | Use the same familiar routine every day; keep all items visible on the counter; a picture card of the steps |
| 3 | Hand over one item at a time; give one-step verbal cues; a caregiver completes the hot-water step |
| 2 | Caregiver prepares the drink; the person holds the cup with help |
General strategies:
- Simplify tasks and break them into steps that match the level
- Make cues visible: labels, pictures, items laid out in order
- Keep routines consistent
- Remove hazards at lower levels: knives, stove knobs, medication
- Train caregivers to give just enough help, not too much and not too little
- Choose meaningful activities the person can succeed at. See OT activities for dementia.
Strengths and limitations
| Strengths | Limitations |
|---|---|
| Practical and easy for caregivers to understand | Levels can oversimplify complex cognition |
| Strong focus on safety and realistic support | ACLS performance can be affected by vision, hand function or culture |
| Useful for discharge planning and care levels | May underplay potential for recovery in some conditions |
| Widely used in dementia and mental health | Research on prediction of function is mixed |
Case example
Mrs Kaur, 79, has moderate Alzheimer’s disease. Her ACLS score is 4.0. She can make tea using her own kettle in her own kitchen, but she left the stove on twice last month.
- Keep tea-making the same every day with items visible on the counter
- Fit an automatic stove shut-off and remove knobs when not in use
- Daily visits from family to check medication (in a locked dispenser)
- Meaningful familiar tasks: folding laundry, watering plants

Summary
Claudia Allen’s cognitive disability frame of reference links cognitive level to everyday function. By assessing the level, with tools like the ACLS, and adapting tasks, environments and caregiver support to match, occupational therapists help people with dementia, mental illness and brain injury function as safely and independently as possible.
