What is IQ?

IQ (Intelligence Quotient) is a score that is determined by an assessment of your reasoning and problem-solving abilities. IQ is descriptive of how you think, but not of how much you know. The average score is 100, which is useful when comparing your thinking/learning performance to that of others. IQ does not reflect creativity, emotions, or functioning competencies, as those are other parts of your intelligence as a whole.

How Are IQ Tests Performed?

Tests are conducted online and in person. Online IQ Tests are dependent on Websites or Apps, offering instant reports after finishing tests. In-person tests need you to visit the designated location, where they are supervised by a qualified proctor or conducted one-on-one by a licensed psychologist. Reports from in-person tests are not provided immediately and typically require higher costs.

What Does An IQ Test Check For?

An IQ test is not aimed to measure your knowledge; instead, it assesses your brain's fundamental ability to process information—think of it as the "operating system" of your brain. It primarily evaluates 4 key areas: problem-solving skills, working memory, verbal reasoning, and visual processing abilities.

How to Select a Trustworthy Test?

For online tests: Select platforms that clearly explain their methods, use professionally developed questions, and prioritize data privacy. Be cautious of promotional claims like "created by scientists."

For In-Person Tests: Some reliable avenues include supervised examinations (e.g., Mensa Admission Test) or evaluations used by psychology for professional purposes (e.g., Wechsler and Stanford-Binet assessments), which will be administered by a psychologist.

What to Do Before Taking An IQ Test?

Physical Preparation: Make sure you get a good sleep, eat healthy meals, and stay well-hydrated.

Mental Preparation: Stay calm and treat the test as a chance to learn about yourself. You can familiarize yourself with question types (e.g., matrix reasoning or number patterns) by practicing official sample tests.

Practical Preparation: Choose a time to test when you are most awake and focused, such as in the morning. If you are taking an online test, choose a room that is quiet and where you have a strong internet connection. If taking a test at a physical location, determine how you will travel there to reduce the anxiety.
