What exactly is an IQ Test?

An Intelligence Quotient (IQ) test is a standardized assessment designed to evaluate an individual's cognitive abilities. These assessments typically encompass a range of questions to assess mathematical aptitude, processing speed, language proficiency, and other cognitive skills. IQ tests serve various purposes, including aiding hiring processes, educational evaluations, diagnostic assessments, or simply for personal interest. On average, IQ test scores typically fall between 90 and 109.

What is a great IQ score?

In determining what constitutes a favorable IQ score, it's essential to understand the distribution and grading system employed in IQ testing. IQ test scores are typically plotted on a bell curve, allowing for comparison against the performance of a standardized sample population. The average IQ score is defined as 100, representing the midpoint of the distribution. Within this framework, the majority of test-takers tend to achieve scores falling within a range from 85 to 118.

Scores above 130 are commonly interpreted as indicative of gifted intelligence, suggesting exceptional cognitive abilities beyond the norm. Conversely, scores below 70 may raise concerns about the presence of developmental or cognitive disabilities, necessitating further evaluation and support. It's worth noting, however, that only a small fraction of individuals register scores at these extreme ends of the spectrum, highlighting the rarity of such outcomes within the broader population.

What are the different types of IQ tests available?

There are different types of IQ tests available depending on the need for taking one. Some are completed in a professional setting and others, such as the ones listed in this article can be completed at home. Two of the most common tests used internationally are The Wechsler Adult Intelligence Scale (WAIS) and Raven's Progressive Matrices, although these usually require a fee.

Can I Practice IQ Tests? 

Although it is possible to retake IQ tests, it is improbable that doing so will significantly alter your actual IQ score. However, retaking the test may afford you the opportunity to become more accustomed to the format and types of questions typically encountered, potentially aiding in better preparation for future attempts.

However, when it comes to online IQ tests, the offerings run the gamut from paywalled results to phishing sites. For many people, finding reputable, accurate tests can be more challenging than taking the assessment. 

If you’re wondering where you rank, we’ve compiled a list of the 21 best free IQ test options you can complete from the comfort of your couch.

Closing Considerations:

It's essential to recognize that even the most comprehensive free IQ test available cannot fully assess every aspect that contributes to one's intelligence and capabilities as a human being. Each individual possesses a unique set of strengths and weaknesses, with varying degrees of proficiency across different domains.

Therefore, it's crucial not to allow a seemingly low score on an IQ test to undermine your perception of your own brilliance or potential. Intelligence encompasses a broad spectrum of abilities, talents, and qualities that extend beyond the confines of a single test score. Embracing and leveraging your distinct talents and capabilities can lead to fulfillment and success in various aspects of life, irrespective of any numerical assessment.
