* Wechsler Adult Intelligence Scale (WAIS): While titled "Adult," the WAIS-IV is often used with high schoolers, particularly older ones, nearing adulthood, because it's considered more appropriate for mature cognitive abilities than tests designed for younger children.
* Wechsler Intelligence Scale for Children (WISC): The WISC-V is typically used for children and adolescents, and might be used with younger high school students. The cutoff isn't rigidly defined, and a psychologist will determine the best fit.
* Stanford-Binet Intelligence Scales: This is another widely used test that covers a broad age range, including adolescents. Again, a professional will choose the appropriate version based on the student's age and developmental level.
Important Note: It's crucial to understand that IQ tests should only be administered and interpreted by qualified professionals like licensed psychologists or psychometrists. Online "IQ tests" are generally unreliable and shouldn't be used for serious assessment. The results of a professionally administered IQ test are just one piece of information to understand a student's abilities and needs. Other factors like learning styles, motivation, and educational experiences are equally important.
