What is the highest score achieved on a Wechsler?

The Wechsler scales, including the Wechsler Adult Intelligence Scale (WAIS) and the Wechsler Intelligence Scale for Children (WISC), have a maximum possible IQ score of 160. However, scores above 130 are often considered to be in the "gifted" range. It's important to note that while a high score can indicate exceptional cognitive abilities, it does not encompass all aspects of intelligence. Additionally, scores can vary based on the specific version of the test and the population being assessed.
