No, you can't fail an IQ test. There's no pass/fail. IQ tests are based on the normal curve, assuming that most people would fall within a certain range of scores (80-109 for example) and those at the extremities (69 and below or 120 and above) would be your exceptionalities--such as gifted or mentally deficient. BTW, 70-79 would be borderline and 110-119 would be high average. The meaning of the numbers varies by the test you take. A score of 120 might mean gifted on one test and average on another. You get a more accurate estimate of your standing in relation to the norms with your percentile score. If you scored at the 95th percentile that would mean you scored higher than 94% of those taking the same test.
