This list is NOT believable.
Some idiot pulled it out of his or her butt. Hardly anybody is given I.Q. tests these days except for one of two reasons: placement in special education programs and help in diagnosing various mental disorders for disability claims and such.
These tests are not given out like candy, and in some states like California, the tests have been banned for K-12 students because of obvious biases. Outside of my brother, I have never personally known anybody who was administered the test except for students I had personally tested in order to see if the student qualified for special education. You have to be qualified to administer them, and it is typically either an educator/school psychologist or a psychologist/psychiatrist. There has to be a valid reason to administer these tests. Taking some garbage quiz for Mensa doesn’t count. Doubt many employers use them either without risking a lawsuit for racial bias and discrimination.
The military has used it as a tool to weed out candidates, but again the tests are administered by qualified people. They do not measure "intelligence" but are used as diagnostic tools.
Where I.Q. tests have been banned for K-12 students, Response to Intervention was designed to replace those tests so that they are not as culturally biased as the old I.Q. tests like the Wechsler Intelligence Scale (WISC), which is the test I used to determine sped eligibility, Stanford-Binet, and a few others whose names don't come immediately to mind. Kids who score low aren't "stupid," but they may be lower than grade level and need extra support in the classroom. RTI has three tiers to it, and the where those kids are ranked determines how much extra support they get in the classroom. The kids in the highest tier are the ones most likely to require special education.
RTI was and is a scheme to reduce the need for "expensive" school psychologists and special education teachers, but, a decade after it was required of schools, it hasn't turned out that way.
