Direct Answer: IQ 115 vs 120

- IQ 115: ~84th percentile, strong generalist careers
- IQ 120: ~91st percentile, competitive for many selective programs
- Gap: often within retest margin—verify before over-interpreting
School, Exams, and Gifted Placement
Many gifted programs use local norms or composite scores, not a single IQ cutoff. 115 may qualify in some districts; 120 is more comfortable where cutoffs sit near the top 10%.
Standardized exams (SAT, GRE, LSAT) correlate with IQ but also reward preparation. See IQ 120 vs 130 if you are near Mensa-level discussion.
Career and Learning Implications
Employers rarely see IQ scores; they see credentials and output. Both 115 and 120 support professional tracks in business, health sciences, engineering, and law with appropriate training.
