Gibson Assessment of Cognitive Skills

The Gibson Assessment of Cognitive Skills (GACS) is a screening tool that informs clinicians, educators, and parents about performance on tasks that measure:

  • Working memory

  • Processing speed

  • Visual processing

  • Auditory processing

  • Logic and reasoning

  • Word attack skills. 

  • Attention and focus levels


 Cognitive Skills Profile

The test scientifically measures the performance of key cognitive skills: memory, processing speed, auditory processing, visual processing, logic & reasoning, and word attack skills. 


Once cognitive weaknesses are identified, they can be strengthened, which typically addresses the root cause of the problem and removes frustrating obstacles to learning. Weak skills can be strengthened through brain training.


The assessment was first developed in 2002 by pediatric behavioral optometrist, Dr. Ken Gibson and is primarily used as a screening tool for clients prior to the start of their cognitive development program. a screening assessment for his cognitive training program.


Dr. Gibson devoted his entire career to helping people with learning disabilities overcome their learning challenges. He knew that assessment was a critical piece of that process. The Gibson Assessment is used to identify cognitive strengths and weaknesses in children and adults ages five and older. The test scientifically measures functioning in key foundational cognitive skills. The root of many learning problems is typically revealed by identifying cognitive weaknesses. In turn, the most appropriate intervention can be selected. For example, weak cognitive skills can be strengthened through intense, one-on-one brain training. 


The assessment is used around the world in clinics, schools, by research and in Kuwait by Brainbox!
