20 Best IQ Quiz Questions for Your IQ Quiz


IQ or intelligence quotient is a metric that is often used to evaluate someone’s psychological abilities to decide their eligibility for a specific program.  

However, the existence and the use of not just IQ quizzes but all quizzes have long been debated. 

But the quizzes are here to stay. 

In fact, IQ quizzes are one of the most accurate ways of measuring a person’s intelligence. Even though you may think how a question followed by four options can measure something as complex as intelligence. 

But they do, and they do it very well. 

IQ Scale


123test, an online IQ test platform, even suggests that only 2.1% of the population has an IQ above 130, and they are classified as “extremely gifted.” 

On the contrary, 6.4% of the people are considered “cognitively impaired” as their IQ ranges between 70-79

Creating a baseline and measuring the cognitive capabilities so seamlessly is only possible through online quizzes.

Also, IQ quizzes are no gimmick. 

They are far more challenging than your average trivia or a knowledge quiz.

But the challenge doesn’t end there because coming up with IQ test questions to build a challenging IQ quiz is equally difficult. 

But you need not fret. We’ll talk about the must-have questions in an IQ quiz in detail, along with everything you need to know about IQ quizzes. So sit tight and keep your eyes peeled. 

What is an IQ Test?

IQ or Intelligence Quotient test refers to an assessment that measures the range of cognitive abilities of the individual and provides a numeric score that is representative of the intellectual abilities and mental age of that individual. 

So an IQ test measures the IQ. 

But what is IQ?

Simply put, IQ is the measurement of an individual’s reasoning and thinking ability. 

It represents the extent of a person’s ability to use information and logic to solve problems and make predictions. 

This is exactly what IQ tests are meant to find out. 

They assess these qualities by measuring the short and long-term memory of the people and also how well they solve puzzles and recall information. 

Intelligence Testing


Did you know?The concept of IQ was first introduced by a German psychologist William Stern and was first used by a French psychologist Alfred Binet in the early 1900s

Ideally, an IQ quiz will have multiple types of high IQ questions to test individuals on the above parameters. These types include: 

  • Analogies
  • Spatial and mathematical patterns
  • Classification
  • Visual
  • Logical

Every person thinks and acts differently, and most of it can be attributed to a person’s IQ. Some people have a better understanding of the world, and some don’t, hence the low IQ.

But let’s say you measured your IQ and got a score, to get an idea of how you fared, you need to know what’s considered a high IQ score.

Well, people with an IQ of over 130+ are considered to be extremely intelligent and way superior to the average person. 

However, people who score 69 or below can be classed as mildly impaired or disabled. 

Here is a table for your reference:

IQ Score Descriptive Classification
130+ Gifted or very superior
120-129 Superior 
110-119 High Average
90-109 Average
80-89 Low Average 
70-79 Borderline impaired
69 or below Mildly impared or diabled
Did you know?In 2016, 11-year-old Kashmea Wahi or Great Britain scored 162 on an IQ test. This score is quite similar to the scores of Stephen Hawkings and even Albert Einstein.

But does that mean she will go on to become the next Stephen Hawking or Albert Einstein?

Maybe, or maybe not. 

Anyhow, now you know that IQ tests have a long successful history of measuring the capacity of a human mind. Let’s take a look at some of the types of IQ tests that exist.

Types of IQ Tests

Since the introduction, IQ tests have come a long way and have been subjected to decades of testing and development. 

Today, we have tons of IQ trick tests, some with major and some with minor variations from the others. Let’s have a look at some of the most commonly used IQ tests out there: 

1. Differential Ability Scales

Differential Abilities Scale (DAS-II) provides detailed insights into the cognitive abilities of children when they are in the learning phase. The scores of this test highlight how interventions can be helpful in the development of those children.

It contains 20 main tests and 17 additional subtests that are given to the test takers.

Differential Ability Scales 


The tests contain a mix of verbal and non-verbal questions, and the age of children determines what test will be given to them. 

Recommended Age: 2 to 17 years of age.

Score Interpretation: Standard score and percentile by age.

2. Kaufman Brief Intelligence Test

The Kaufman Brief Intelligence Test (KBIT-2) is an individually administered, brief test that aims to measure the verbal and nonverbal intelligence of the test takers. These tests can also identify children at high risk who may require a more comprehensive evaluation. 

The KBIT-2 Test is ideal to be used in education, clinical or research settings. 

The test was primarily created and used to assess people with gifted intelligence. It can only be given in English, or it may defeat the purpose of this intelligence test.

Recommended Age: 4 to 90 years of age

Score Interpretation: Crystallized, fluid, IQ composite.

3. Raven’s Progressive Matrices

Raven’s Progressive Matrices (RPM) is a non-verbal test that measures general human intelligence using sensory images to get an estimate of an individual’s fluid intelligence. 

It contains 60 IQ test questions with sensory images, and the questions tend to get progressively harder. 

Raven's Progressive Matrices


This test is especially great to assess the problem-solving and deductive reasoning of the test takers. 

Recommended Age: 5 to 60 years of age

Score Interpretation: Summary and detailed percentile

4. Reynolds Intellectual Assessment Scales

The Reynolds Intellectual Assessment Scales (RIAS) is not only comprehensive and cost-effective but also of high quality and reliable to clinicians in making decisions about classification, education, selection, and placement. 

It is a quick memory assessment that assesses both verbal and non-verbal skills and is responsible for measuring the cognitive abilities of a person to remember certain actions and words.

Reynolds Intellectual Assessment Scales


The test includes 4 main tests, and more subtests can be added as per the need. 

Talking about administration, a total of 4 tests only take about 20 to 25 minutes, with just 10 additional minutes for memory assessment. 

Recommended Age: 3 to 94 years of age

Score Interpretation: Median score and standard deviation

5. Woodcock-Johnson Test of Cognitive Abilities

The Woodcock-Johnson (WJ-III) test is a comprehensive series of exams that are designed to measure general intellectual abilities along with academic performance, oral language, cognitive ability, and scholastic aptitude. 

These tests can be used for a range of activities, including planning individual and educational programs, diagnosing learning disabilities, and for organizational research. 

Woodcock-Johnson Test of Cognitive Abilities


The WJ-III includes 10 standard battery tests and 10 more extended battery tests. It has both long and short forms of tests and is best for measuring the cognitive abilities of the test takers. 

Recommended Age: 2 to 90 years of age

Score Interpretation: Standard score and detailed percentile

If we start to list down, there are tons of IQ tests that can be administered to the test takers. However, these 5 are the most common and flexible IQ tests that you can take or administer to assess the cognitive abilities of the test takers.

Now let’s move ahead and look at some of the uses of IQ tests. 

Uses of IQ Tests

There are plenty of ways in which IQ tests can be used; here are some of the most common ones:

1. Educational Assessment and Placement

Educational assessments and placements act as a guidance program for students to plan better for their future and also look for suitable employment options based on their own abilities and skills. 

This is why it’s important to determine the students’ intelligence level to ensure that they’ll be able to succeed when they have to become a professional.

Educational Assessment and Placement


The best way to do this is by assessing them using standardized tests with IQ test questions, which will assess their capacity to think rationally and deal effectively with day-to-day problems. 

The tests will also highlight the problematic areas of the specific students, which will help in guiding them towards a more appropriate career path.

2. Cognitive Research

As we know, IQ tests are responsible for characterizing the efficiency in which an individual gathers and processes information that can be termed as cognitive. 

In simple terms, IQ tests leave out the non-cognitive aspects of the test takers like interpersonal skills or socio-emotional skills and measure their cognitive abilities in detail. 
These IQ tests are then subjected to different research and used to predict variations and performance in different activities such as learning, reasoning, and problem-solving. 

Also, the critique of IQ tests leads to the inception of several broad psychological theories of intelligence that may lay the foundation for the future. 

3. Job Candidate Evaluation

Career assessments have become an integrated part of every recruitment process. 

They give extremely valuable insights as to how a given candidate can use their skills in the workplace to garner substantial long-term results.

When done perfectly, businesses can assess potential candidates using IQ tests. They can hire individuals who exhibit better adaptability and flexibility to learn and grow within the business while contributing towards the goals and reducing costs.
