Extra Insight: When Should You Choose a Psychologist?

Despite the convenience of online tests, some situations require formal evaluation by a licensed psychologist. Choose in-person testing if you:

• Need documentation for academic accommodations
• Suspect ADHD, dyslexia, or cognitive delays

In these cases, clinical-grade IQ tests like the WAIS, WISC, or Stanford-Binet are recommended.
