How does IQ testing help identify learning disabilities?

IQ subtests reveal cognitive profiles. A child with average IQ but low processing speed and working memory subtest scores may have a specific learning disability.

What is the discrepancy model?

The discrepancy model identifies learning disabilities when there's a significant gap between overall IQ and achievement in a specific academic area.

Can someone have high IQ and learning disabilities?

Yes. Twice-exceptional children have high IQ with dyslexia, dyscalculia, or processing disorders, often underachieving academically.

What supports help learning-disabled students?

Specialized instruction, assistive technology, accommodations (extra time), and cognitive training can help learning-disabled students succeed despite IQ-achievement discrepancies.
