IQ Score of 89 at Age 16: Interpretation and Context

Score Meaning

• Standard IQ scale: Mean 100, SD 15 (Wechsler).
• 89 falls in the "Low Average" range (80–89).
• Percentile: ~23rd percentile (performs better than ~23% of age peers).

Important Context

• IQ is a snapshot of cognitive performance on a specific day; not a fixed trait.
• Subtest scatter (variability across verbal, visual-spatial, working memory, processing speed) is more informative than full-scale score alone.
• Factors affecting score: test conditions, attention, anxiety, motivation, cultural/language bias, learning disabilities.
• An IQ of 89 does not indicate intellectual disability (threshold ~70 with adaptive deficits).

Next Steps

1. Review the full report with the psychologist—ask about index scores and confidence intervals.
2. If academic struggles exist, request educational evaluation for specific learning disabilities (dyslexia, dyscalculia, ADHD).
3. Focus on strengths; support weaknesses with accommodations (extra time, assistive tech, scaffolded instruction).
4. Intelligence is multifaceted; creativity, emotional intelligence, grit, and practical skills are not captured by IQ.
