What does an IQ of 135 mean?
An IQ of 135 is at or above 130 — the conventional "gifted" threshold and roughly the top 2% of the population. Scoring higher than about 99% of people, 135 is a genuinely high result, and it's around here that organisations like Mensa set their entry bar.

Is an IQ of 135 good?
Yes — an IQ of 135 is a high score by any standard, at or above the gifted threshold of 130. Abstract reasoning at this level is a real asset for technical and research-heavy work. It's worth keeping perspective, though: "gifted" describes one measured ability, and outcomes still hinge on effort, environment, and what you choose to pursue.
How rare is an IQ of 135?
An IQ of 135 is rare: only about 1.0% of people score this high — about 1 in 102. In a random group of 1,000, roughly 10 would reach 135 or above.
What an IQ of 135 looks like in practice
People at the gifted level often handle highly abstract problems with ease and seek out intellectually demanding work. A high score opens doors but doesn't guarantee results — direction and discipline still do the heavy lifting.
IQ 135 compared to nearby scores
No short test pins ability to a single point. An IQ of 135 is best read as the centre of a range — roughly 131 to 139 — rather than an exact value, and it is not meaningfully different from scores a few points either side. When you compare two people, overlapping ranges matter more than the point scores.
