Will Hunting's IQ, and what Good Will Hunting's IQ Score actually reveals.
How smart is Will Hunting? Smart enough that "Will Hunting's IQ" is one of the most searched questions about Good Will Hunting. Here is the defensible read of the mind the show actually builds, the 156/200 IQ Score behind it, and why no invented number does it justice.
The answer
Will Hunting anchors Good Will Hunting as one of its central intelligences, and the show earns a 156/200 IQ Score (Stimulating tier) for how seriously it builds that mind. That score is the real, measurable answer the search is circling. The specific IQ figures floating around online are invented; no clinical IQ test applies to a fictional character, and TVI does not fabricate one. We rate the work, not the character, on a published 0 to 200 rubric.
Who Will Hunting is, and what kind of intelligence the show actually depicts
Will Hunting (Matt Damon) is MIT janitor with a mathematical mind that nobody around him initially recognizes, the film treats his intelligence as the central cognitive material but also as the source of his most consequential avoidance behaviors. The character's intellectual signature in the show is autodidact mathematical reasoning, photographic memory, intelligence-as-defense-mechanism, the rare portrayal of genius as something a person might want to escape from rather than perform.
This is the part of the question "what is Will Hunting's IQ" that the search engine flattens. The real question, the one viewers are circling, is whether the show treats Will Hunting's mind seriously. That's the question TVI can actually answer.
What the IQ Score reveals about the portrayal
Good Will Hunting scores 156/200 (Stimulating tier) because Gus Van Sant and the Damon/Affleck script treat genius as a moral and emotional problem rather than as a triumph. The film's cognitive material is real, the math is real, the philosophy is real, the therapy is real, but the rubric weights it as Stimulating rather than Masterclass because the structural argument compresses into the standard redemption-arc shape rather than extending into more sustained territory.
