What is Jim Parsons’ IQ?
The famous 187 is spoken by Sheldon Cooper in a joke about soup; it was never a measurement of the man who plays him.
No Jim Parsons IQ test result has been published. The 187 beside his name is the IQ his character Sheldon Cooper states on The Big Bang Theory; what is documented is a theatre BA (Houston, 1996), an MFA (Old Globe/University of San Diego, 2001) and four Emmys.
Jim Parsons’ estimated IQ
- BA in theatre from the University of Houston School of Theatre and Dance, 1996; he was also a founding member of the Houston company Infernal Bridegroom Productions.
- MFA from the Old Globe/University of San Diego graduate theatre program, 2001, a two-year classical-acting course he entered in 1999.
- Four Primetime Emmy Awards for Outstanding Lead Actor in a Comedy Series (2010, 2011, 2013, 2014) and the 2011 Golden Globe for the same role, from nine Emmy nominations in all.
- Broadway roles including The Normal Heart (2011), Harvey (2012), An Act of God (2015), The Boys in the Band (2018) and Mother Play (2024), which brought a Tony nomination for Best Featured Actor in a Play.
- His own account of school: good grades once he started doing theatre, and one F, in a college meteorology class (Newsweek, 2009).
No IQ test score has been published for Parsons, and what is documented is a craft record: two theatre degrees and a career built on skills such as memory for text, timing and stagecraft, none of which an IQ test isolates. The range is deliberately loose, and it sits far below both figures that circulate, as a sourced range usually does.

What an IQ of 120–135 actually means
Set the claim aside for a moment. If someone genuinely scored in this range, here is what that would represent.
Average is 100 by construction, and about two-thirds of people fall between 85 and 115. Take the test to place your own score on this scale.
| Score range | Classification | Share of people | What it indicates |
|---|---|---|---|
| 85 – 114 | Average | ~68% | The range most people fall into. |
| 115 – 129 | Above average | ~13.6% | Roughly one person in seven. |
| 130 – 144 | Gifted | ~2% | The threshold most high-IQ societies use. |
| Above 144 | Highly gifted | ~0.1% | Figures above this range are extrapolated from the curve rather than measured. |
Percentages are approximate and describe a normal distribution. The same number means different things on tests with different standard deviations.
Thirty questions gives you a measured position on this exact scale — your score, your percentile and the ability breakdown behind it.

Jim Parsons was born on March 24, 1973 in Houston, Texas, and grew up in Spring, one of the city’s northern suburbs. He went to Klein Oak High School and then to the University of Houston, where he took a BA in theatre from the School of Theatre and Dance in 1996 and was a founding member of the Houston company Infernal Bridegroom Productions. In 1999 he entered the two-year classical-acting program run by the Old Globe theatre in San Diego with the University of San Diego, and he graduated with an MFA in 2001.
His early work was on stage and in small film and television parts, among them Garden State and a recurring role on Judging Amy, before he was cast as Sheldon Cooper in The Big Bang Theory, the CBS comedy created by Chuck Lorre and Bill Prady. It ran for 12 seasons and 279 episodes, from September 24, 2007 to May 16, 2019, with Johnny Galecki as Leonard Hofstadter and, from the fourth season, Mayim Bialik as Amy Farrah Fowler.
The Television Academy credits Parsons with four Primetime Emmy Awards for Outstanding Lead Actor in a Comedy Series, in 2010, 2011, 2013 and 2014, from nine nominations in all; the others include The Normal Heart (2014), Special (2019, as an executive producer) and Hollywood (2020). He also won the Golden Globe for best actor in a television series, musical or comedy, in 2011. For the wider picture of schooling and test scores, see average IQ by education level; acting honors, though, are judged on craft, and none of these is a score.
On stage he has worked on Broadway in The Normal Heart (2011, as Tommy Boatwright), Harvey (2012), An Act of God (2015), The Boys in the Band (2018), Mother Play (2024), which brought a Tony Award nomination for best featured actor in a play, and Our Town (2024–2025). From 2017 to 2024 he narrated Young Sheldon, the prequel that follows the character as a child.

Where the 187 figure came from
Following a claim back to its first appearance is the part almost nobody does — and it is what most people are actually asking.
What is the IQ of Jim Parsons? Search the question and the number that comes back is 187, and it belongs to Sheldon Cooper. The character says it himself in “The Pancake Batter Anomaly”, season 1, episode 11 of The Big Bang Theory, first aired on March 31, 2008. Ill, Sheldon tells Penny “I have an IQ of 187” and asks whether he would not have thought of a way to have soup at home; she points out that soup can be delivered, and he concedes he had not thought of that. Wikipedia’s entry for the character notes that Sheldon frequently states the number, and the prequel Young Sheldon, which Parsons narrates, has the child version repeat it in an episode of March 2, 2023. It is a scripted boast played for laughs, not a measurement of the actor who delivers it.
The slide from character to actor is visible on the pages that carry it. realiqtestonline.com and en.celebrity.tn print 187 under a Jim Parsons IQ headline and then say in the body that it is the character’s: the headline promises an IQ for the actor and the text delivers one for the role. celebsiq.com goes a step further and lists a Jim Parsons IQ level of 173, arguing that in “an interview” he said his and Sheldon’s IQs combined were 360. The page names no interview, date or publication, and we could not find one. A 360 does exist, but it is script: in the pilot, first aired on September 24, 2007, Leonard Hofstadter (Johnny Galecki’s character) says he and Sheldon have a combined IQ of 360 while they are locked out of a building, and moments later two girls selling cookies ring every buzzer and the door opens. Subtract Sheldon’s 187 and 173 is left, the figure fans credit to Leonard: a second fictional character, not the man who plays Sheldon.
Neither number could be a test result. Most modern IQ scales are set to a mean of 100 and a standard deviation of 15, which puts 187 at 5.8 standard deviations above the mean and 173 at 4.9. The WAIS-IV, an adult Wechsler scale, can report a full-scale IQ only between 40 and 160, and reports of scores far above 160 are treated as dubious; the IQ ceiling effect and the highest score a test can report explain why the top of a scale cannot simply be stretched. Wikipedia’s summary of the character even has Sheldon claiming that his IQ cannot be accurately measured by normal tests. In the sitcom the figure works as shorthand for genius; as a claim about the actor it has nothing under it.
The record that does exist is a theatre student’s, and Parsons has been plain about it. In a 2009 Newsweek roundtable he said he got good grades once he started doing theatre, that the one F he ever received came in a college meteorology class, and that he would still be in school if there were a doctorate in acting; in 2011 he told CBS’s Early Show, “I’m not stupid. But I’m no genius.” This site’s estimated IQ range for him, 120–135, sits level with Matt Damon’s, whose page traces the same habit of crediting an actor with a fictional genius’s intelligence, and just under Benedict Cumberbatch’s, another actor best known for playing a fictional genius, Sherlock Holmes. It sits well below the range for Mayim Bialik, who played Amy Farrah Fowler in the same series and holds a completed UCLA doctorate in neuroscience. The wider pattern is covered in where celebrity IQ numbers come from; a number for a living person has to come from a test that person took, such as the IQ Metrics test, not from a script.
How we read a number →Source of both lines: Sheldon’s “an IQ of 187” in episode 11 and Leonard’s “a combined IQ of 360” in the pilot. Fan-made transcripts, not re-watched, but the two sites agree on the wording of the sentences used.
Four Emmy wins for Outstanding Lead Actor in a Comedy Series (2010, 2011, 2013, 2014) from nine nominations, including The Normal Heart (2014), Special (2019) and Hollywood (2020); one Golden Globe win (2011) from four nominations.
Parsons’s own account of school: good grades once he started doing theatre, one F (a college meteorology class), and that he would still be in school if a doctorate in acting existed.
Reports Parsons telling Early Show co-anchor Chris Wragge, “I’m not stupid. But I’m no genius.” The headline is CBS’s paraphrase; the quoted sentence is his. The piece also confirms he was then playing Tommy Boatwright in The Normal Heart on Broadway.
MFA from the Old Globe/USD graduate theatre program in 2001 (KPBS and NBC 7 agree); BA from the UH School of Theatre and Dance in 1996 (the student newspaper and a speaker-bureau biography agree).
Orientation and cross-checks: series dates and creators, the character’s 187 and degrees, Young Sheldon narration, the Mother Play Tony nomination, the WAIS-IV score range (40 to 160) and the 100/15 scale. Broadway dates agree between Wikipedia and New York Theatre Guide.
Independent write-ups: riotiq.com quotes Sheldon’s 187 line, Leonard’s “combined IQ of 360” line and the fans’ subtraction to 173, and finds the Young Sheldon repeat. The others print 187 as the character’s and repeat the CBS quote. None gives a test result for Parsons.
celebsiq.com states “IQ Level = 173” and cites an unnamed interview and a combined 360. realiqtestonline.com and en.celebrity.tn print 187 as Sheldon’s and give the actor no number; iqtesta.com says his IQ is unknown. None cites a test.
None found in school, testing-body, society or interview sources, and none of the pages above claims one. Parsons has not stated a number himself in any interview we could open.
The sources behind our estimate
The figures that circulate for Jim Parsons, what we were able to confirm, and where the two diverge.
The Jim Parsons IQ score that turns up on the pages we opened is 187, which is Sheldon Cooper’s, stated by the character on screen. One aggregator, celebsiq.com, goes further and gives the actor himself “IQ Level = 173”, reasoning from a combined 360 that it says he mentioned in an interview.
We found no published IQ test result for Jim Parsons. celebsiq.com cites no test, examiner or date, names no interview and shows no disclaimer on the page; the only 360 we could find is dialogue in the show’s pilot, spoken by Leonard Hofstadter about himself and Sheldon. realiqtestonline.com and en.celebrity.tn print 187 under a Jim Parsons IQ headline but attribute it to Sheldon and give the actor no number; iqtesta.com says his IQ is unknown. Parsons himself told CBS in 2011 that he is “not stupid” but “no genius.”
The documented record supports the two lower numbers, which are an estimated range. The two upper numbers echo a script: 187 is Sheldon’s, spoken on screen, and 173 is what remains when Sheldon’s is subtracted from a total the pilot gives for him and Leonard. Both sit above the 160 top of the WAIS-IV’s reporting range, and both are far above anything the record supports.

Jim Parsons — frequently asked
What is Jim Parsons’s IQ?
No IQ test result has ever been published for Jim Parsons, so his IQ in real life is unknown. The 187 that appears beside his name is the IQ his character Sheldon Cooper states on The Big Bang Theory. This site’s estimated IQ range of 120–135 is inferred from his degrees, awards and stage career, not from a test.
Is Jim Parsons’s IQ 187, like Sheldon Cooper’s?
No. The 187 is a line of dialogue: Sheldon says he has an IQ of 187 in “The Pancake Batter Anomaly”, season 1, episode 11 of The Big Bang Theory, first aired on March 31, 2008. It is a fictional character’s boast, and no test result of any kind has been published for the actor who plays him.
Did Jim Parsons take an IQ test?
There is no public record of it. We found no published test result, and none of the pages we checked claims Mensa membership or cites a school-administered score. Parsons has not stated a number himself; the nearest thing is his 2011 remark to CBS that he is “not stupid” but “no genius.”
Is Jim Parsons a genius?
He does not claim to be. Parsons told CBS’s Early Show in 2011, “I’m not stupid. But I’m no genius.” What is documented is achievement in acting: a theatre BA, an MFA, four Emmys and a Golden Globe for playing Sheldon Cooper, and Broadway roles. None of that is an IQ score.
Where does the 173 IQ for Jim Parsons come from?
It comes from one aggregator, celebsiq.com, which says Parsons stated in an interview that his and Sheldon’s IQs combined were 360, then subtracts Sheldon’s 187. The page names no interview. The 360 total matches a line in the show’s pilot, where Leonard Hofstadter says he and Sheldon have a combined IQ of 360.
What degrees does Jim Parsons have?
Jim Parsons holds a BA in theatre from the University of Houston (1996) and an MFA from the Old Globe/University of San Diego graduate theatre program (2001). Both are arts degrees. His character Sheldon Cooper, by contrast, is written with five degrees including a PhD; the actor’s two are the ones listed here.
How does Jim Parsons’s estimated IQ compare with Mayim Bialik’s?
This site’s estimated range for Parsons, 120–135, is lower than the 140–155 given to his Big Bang Theory co-star Mayim Bialik. The gap reflects the record: Bialik completed a UCLA neuroscience PhD in 2007, while Parsons’s degrees are in theatre. Both ranges are inferences from documented achievement, not test scores.
How does my IQ compare with Jim Parsons?
You can find out in about fifteen minutes. The IQ Metrics assessment is 30 questions, scored on the same 100-mean scale used throughout this page, so your result and the estimate above are at least expressed in the same units — one measured, one inferred. Once you have a number, the leaderboard shows where it would sit, and how we score and norm it explains the benchmarking.
