IQ is usually to test the intelligence level of an individual. Career counselors don't take an IQ test, but take an aptitude test which is used to test the occupational/career relevancy of students. Although academic marks serve as a proxy to test your IQ.
The following two IQ test types are commonly used worldwide:
The Wechsler Adult Intelligence Scale (WAIS);
Raven's Progressive Matrices
Note : Malin's intelligence scale for Indian children is the Indian adaptation for testing IQ.
