How do I practically take a standardized, formal IQ test in the US?

I’m interested in taking a formal IQ test such as the Stanford Binet or the Wechsler test (one that in theory could be used for admission to Mensa). This excludes most website based tests and whatnot.

What is practically involved? I have a pretty good idea about the procedures to register for standardized achievement or admissions testing (e.g. GED, SAT, ACT, GRE, MAT, LSAT, MCAT, etc.), but I don’t see the Stanford Binet as one that one can simply call up and register to take at a local university or public school. Do I need to contact a psychologist or psychiatrist to get it done individually?

I’m not part of any program that would routinely administer IQ tests, such as a program for developmentally disabled people.

Why an adult would want to get a formal IQ test done on themself or whether or not they could accomplish their end purpose through some other means than a formal, standardized IQ test is beyond the scope of this question.

Mensa offers tests. They charge $40 for them. You can find locations on their site.

BTW, in case there is uncertainty, my intention was to ask about how to actually get the test formally administered to myself by someone qualified to administer IQ tests, rather than asking about how to prepare for an IQ test in order to maximize score.

Visit your local university, specifically the psych department. They will probably have some undergrad or grad student who is training on the IQ tests and will happily administer one so they can have the experience of interpreting it and interviewing you afterward. Just be sure to allot some time because they’re going to want to interview you as well as administer the test.

Enjoy,
