Where could you get a real IQ test?

Just run through your search engine of choice "evaluation or educational  psychologists near me," and ask how much they charge for administering either a WISC if you are under 18 or a WAIS if you are an adult.  These Wechsler Intelligence tests are the gold standard.   You can take them online, but the ones administered by a person are more reliable. My late wife was an analyst for the Dept of Justice. Her background check revealed that her IQ was in the "NOT MEASURABLE" range (above genius). She was shepherded to the government's evaluation psychologist and given the government's test before she was hired.  The result:  "The results of the test administered by the Archdiocese of Philadelphia in 1952 are, quite remarkably, confirmed."

For those still in high school, the Child Study Team (cst) may do some testing of students who are having difficulty with academics, the school environment, or both, which usually includes an IQ test.  The cst usually includes a school social worker, learning disabilities teacher-consultant (LDT-C), and school psychologist.  Before testing is to begin, the cst would need the parents' permission.
