What Is The Average IQ Score By Age?


Do you know what IQ stands for? If the answer is ‘no’, you’re in good company…most of us don’t. Here’s everything you need to know.

What Is IQ?

Simply put, your IQ stands for or Intelligence Quotient. It’s a number that represents certain aspects of your cognitive skill. Very left-brain-based, it’s essentially a measurement of your ability to apply logical reasoning to solve problems.

But that doesn’t mean your IQ is ‘better’ than that of a 3-year-old. Or that of a centenarian for that matter. Your IQ is measured against your age too.

How Are IQ Scores Measured?


IQ tests are scored in not one, but two ways. The oldest and most straightforward way to measure your score is by a simple act of comparison against others in your specific age group. The most popular method, however, is more mathematical in that the participants’ mental age (revealed by the IQ test) is divided by their chronological age and then multiplied by 100. 

Your test is designed, mainly, to measure your mathematical abilities, language skills, memory, reasoning skills, and information-processing speed. Your points gained on these subtests are then combined to form an overall IQ score.

What Is The Average IQ Score?

The average IQ score for any age group is 100. You’re actually deemed to be within the ‘normal’ IQ range if you score anywhere between 85-115 on your test. The vast majority of people fall into this category.

Anything under or over that would be considered ‘out of the ordinary’, from ‘exceptionally gifted’ from 130 onwards to ‘intellectually disabled’ for anyone scoring below 70. Harsh.

So in a nutshell, the higher the number, the higher your ‘intelligence’. You can take a test here.

Unfortunately, none of that matters.

Wait, what?

We’re afraid you’ll never get those 2 minutes you just spent reading about IQs back.

What you will get, however, if you keep reading, is the truth.

Why High/Low IQs Do NOT Measure Intelligence

There’s really no such thing as a good or bad IQ score.

Why? Because your IQ is such a narrow measure of specific cognitive abilities. Frankly, it does a poor job of reflecting the vast world of your mental capacities intellectual strengths as a unique individual.

New research in this field has revealed that we may actually possess up to nine different types of intelligence. And you can develop each of them by learning to improve your brain functions.

The Intelligence That Counts

So what field of intelligence would you genuinely like to be sharper in? What’s something completely new you would like to learn? What cognitive abilities would serve you in living your best life? These are the questions that actually count.

Whether you’d like to learn a new language or instrument, learn how to read faster, remember people’s names forever, or just boost your memory in general, it’s never too late. The truth is, your brain is a muscle–and there’s nothing stopping you from training it to be stronger.

That’s right, your ‘intelligence’ isn’t set, and it can improve ten-fold with the right coach.
