Is 148 on an IQ test considered genius level?

The short answer is that it depends on the IQ scale you are referring to and even then it would not indicate that someone is actually a genius.
Actually, to join Mensa one has to prove that he or she has scored at or above two standard deviations above the norm (roughly the 98th percentile) on a real IQ test (not one of the ones on Facebook). Then of course one also has to pay membership dues. On the Cattell Culture Fair IQ scale that would be 148. On the Stanford-Binet that would be 132. On the Wechsler that would be 130. A score of 140 on some scales is actually LESS than a score of 130 on other scales and would not quality. An actual score of 140 on the Wechler would be exceedingly rare (1 in 250+), while a score of 140 on the Cattell would be less rare (about 1 in 20). These scales are based on different statistical methods.
Scoring highly on these tests does not certify a person as a genius (a subjective term). A high score simply shows that a person is likely very intelligent. These scales are intended to help with academic and vocational placement. They are not genius detectors. They do not measure the ability of a person to compose music, prose, or create fine art. A score on an IQ test can also be distorted by any number of factors. Individuals from environments with limited access to academic resources have artificially low scores and individuals who are coached to be familiar with tests have artificially high scores.
Usually prodigies and geniuses are considered to have IQs that are not measurable through conventional means. IQ tests are not useful for measuring intelligence above the ceiling of two standard deviations. For an IQ of 160 to 200 one would need to be professionally assessed by a psychologist specializing in the field of psychometric measurement.
Anything over 140 is considered genius level and makes one eligible to join MENSA. However, the test needs to be conducted properly. On line tests are rather inaccurate, as are the 'take at home' types. The most accurate types of IQ tests are taken while the subject is unaware they are being tested.
Additional Info: The actual scores vary depending on the scale used. Different tests use different scales, just there are different scales on a centigrade and a Fahrenheit thermometer.
There is an excellent graphical representation of the standard distribution of I Q tests in the wikipedia article on the subject. (check related links)
Opinions of contributors: The short answer is that it depends on the test and that even then a high IQ score (whether it be 130 or 148) demonstrates high intelligence, but does not prove genius. IQ tests given to children are ranked depending on the age of the child at the time the test is taken, which makes the tests less reliable than those based on an adult scale. The term genius is subjective and…

Opinions from contributors: . Two standard deviations above the statistical norm is what qualifies a person to join some high IQ societies. It doesn't prove that someone is a genius, but it does indicate a very superior level of intelligence. On the Cattell Culture Fair IQ Scale this would be 148, on the Stanford-Binet it is 132, and on the Wechsler it is 130. The reason the numerical values are not consistent with each other…
It depends on which IQ test you took. If you took the most common test, the Cattel B III test, a score of IQ 148 or higher is required. The only requirement is that the test you take is on their list of acceptable tests, and that you rank in the top two percent of people who have taken that test. You can also take the test by contacting Mensa. See Related Question below for…
No. You are just gloating. There's a lot of people in the world with that IQ. Be smart and keep it to yourself. No. We are all born with different intelligence, and it isn't something we control, so you are fine no matter what IQ you have. As for an IQ of 148, you are very lucky. An IQ of 100 is considered average. Some words of caution: -If you took an online IQ test…
