Cognitive assessment (or intelligence testing) is used to evaluate the general thinking and reasoning abilities of a person, often referred to as intellectual functioning or IQ. Higher IQ scores represent higher cognitive performance and lower scores reflect poor cognitive performance. Nevertheless, individual domain scores that provide a more accurate representation of an individual's cognitive ability than the overall IQ score because the scores between domains differ greatly. Intelligence testing can determine various aspects of a child's cognitive capacity. Such intellectual skills include verbal awareness, visual and spatial perception, logical reasoning, working memory and speed of processing. A cognitive assessment can also help recognize particular areas of strength or weakness in children using psychometric tests, so that effective approaches can be built to improve learning and growth through the implementation of different machine learning models. Recommendations should be provided with a deeper understanding of how a child thinks to improve weak skills and reinforce areas of strength. Sometimes, an assessment can also help to explain certain behaviors that a child may exhibit.
