The WISC, or Wechsler Intelligence Scale for Children, is a widely used test designed to measure the cognitive abilities of children aged 6 to 16. It assesses various aspects of intelligence, including verbal comprehension, perceptual reasoning, working memory, and processing speed. The results help identify a child's strengths and weaknesses in different areas of cognitive functioning. The WISC consists of several subtests, each focusing on specific skills. These subtests are grouped into two main categories: verbal and performance. The test is often used by psychologists and educators to evaluate learning disabilities, giftedness, and overall intellectual development in children.
