Objective

The Ranchos Los Amigos Scale measures the levels of awareness, cognition, behavior and interaction with the environment.

Method of Use

RANCHO LOS AMIGOS SCALE
AKA Level of Cognitive Functioning Scale (LCFS)
(1) Level I - No Response.
Patient does not respond to external stimuli and appears asleep.
(2) Level II - Generalized Response.
Patient reacts to external stimuli in nonspecific, inconsistent, and nonpurposeful manner with
stereotypic and limited responses.
(3) Level III - Localized Response.
Patient responds specifically and inconsistently with delays to stimuli, but may follow simple
commands for motor action.
(4) Level IV - Confused, Agitated Response.
Patient exhibits bizarre, nonpurposeful, incoherent or inappropriate behaviors, has no shortterm
recall, attention is short and nonselective.
(5) Level V - Confused, Inappropriate, Nonagitated Response.
Patient gives random, fragmented, and nonpurposeful responses to complex or unstructured
stimuli - Simple commands are followed consistently, memory and selective attention are
impaired, and new information is not retained.
(6) Level VI - Confused, Appropriate Response.
Patient gives context appropriate, goal-directed responses, dependent upon external input for
direction. There is carry-over for relearned, but not for new tasks, and recent memory
problems persist.
(7) Level VII - Automatic, Appropriate Response.
Patient behaves appropriately in familiar settings, performs daily routines automatically, and
shows carry-over for new learning at lower than normal rates. Patient initiates social
interactions, but judgment remains impaired.
(8) Level VIII - Purposeful, Appropriate Response.
Patient oriented and responds to the environment but abstract reasoning abilities are
decreased relative to premorbid levels.
