    The Wechsler Intelligence Scale for Children (WISC) is an IQ test for children of 6-17 years of age to determine general intelligence. It generates a full scale IQ (formerly known as an intelligence quotient or IQ score) that represents a child's general intellectual ability. The most common primary index scores are the Verbal Comprehension Index, the...
