Understanding the IQ Test Scale

IQ, or Intelligence Quotient, is a measure of a person’s cognitive ability in comparison to the general population. The IQ test has been around for more than a century and provides a snapshot of an individual’s mental agility. To understand more about this measure, one needs to explore the scale at which the IQ score is calculated.

Measuring IQ

IQ is typically measured via standardized tests, such as the Stanford-Binet Intelligence Scales or the Wechsler Adult Intelligence Scale (WAIS). These tests measure intelligence through a series of tasks evaluating reasoning, problem-solving abilities, memory, and more. The score from these tests are then converted into an IQ score.

Stanford-Binet Scale

The Stanford-Binet Scale ranges from 40 to 160+ and is divided into certain categories that represent levels of intelligence. The majority of people, around 68%, score between 85 and 115. Here is how the scale breaks down:

  • Below 70 – Extremely low
  • 70-79 – Borderline
  • 80-89 – Low average
  • 90-109 – Average
  • 110-119 – High average
  • 120-129 – Superior
  • 130 and above – Very superior (or often referred to as ‘gifted’)

Wechsler Scale

The Wechsler Scale, another commonly used IQ testing method, has a bit more granularity than the Stanford-Binet Scale, with scores ranging from 50 to 160. The Wechsler Scale categories involve:

  • Below 70 – Intellectual Disability
  • 70-79 – Borderline Intellectual Functioning
  • 80-89 – Low Average
  • 90-109 – Average
  • 110-119 – High Average
  • 120-129 – Superior
  • 130 and above – Very Superior

Decoding the Scores and Levels

While interpreting IQ, it’s not just about scoring as high as possible. Rather, it’s more valuable to consider what the scores mean in the context of individual ability.

Average Range

Around 68% of the population falls within the average score range, 85-115. This means that if one scores within this band, they share the space with the vast majority of the world’s population, and their cognitive abilities are observed as normal.

The Outliers

Scores below 70 or above 130 is where things get particularly interesting. Scores below 70 may reveal a possible intellectual disability that could affect an individual’s ability to perform certain tasks or jobs. On the other hand, scores above 130 indicate exceptional intellect. People in this category are often considered “gifted.” They may have special abilities, such as superior problem-solving skills, that set them apart from the average population.

The Gray Areas

Scores falling in the borderline, low average, high average, and superior categories often yield more questions than answers. People with these scores might not fall into the neatly defined categories of “average” or “gifted,” but might display a mix of abilities. Interpreting these scores often needs a comprehensive understanding of the person’s competencies and challenges beyond the numeric representation of their intelligence.


Understanding IQ tests and scores helps us acknowledge that intelligence is not a fixed or confined trait but a spectrum of capabilities. Therefore, it’s crucial to not lock personal prospects or self-worth to the IQ score but use it as a means of better self-understanding. Remember, IQ tests measure a slice of mental prowess, but human intelligence is a broad and diverse field, incorporating creativity, emotional intelligence, common sense, and many other facets of intellect.

Albert Einstein: The Genius with an Unparalleled IQ Test Scale Score

When discussing the concept of the IQ test scale, it is impossible to overlook the extraordinary genius of Albert Einstein. Born in 1879, Einstein is widely regarded as one of history’s greatest physicists and scientific thinkers. His contributions to the theory of relativity revolutionized our understanding of space, time, and energy.

Einstein’s brilliance was not only evident through his groundbreaking theories, but also in his exceptional intelligence quotient. While exact IQ scores are subjective, estimations suggest that Einstein’s IQ test scale score ranged between 160 and 190, far surpassing the average IQ of 100.

Several factors contribute to Einstein’s remarkable intellect and performance on IQ tests:

  • Creative Thinking: Einstein possessed an extraordinary ability to think outside the box, approaching complex problems from unconventional angles. This unique perspective allowed him to develop innovative scientific theories.
  • Abstract Reasoning: Einstein excelled in abstract reasoning, a crucial skill for solving complex puzzles and conceptualizing theoretical frameworks. He had a remarkable capacity to visualize and manipulate complex mathematical equations mentally.
  • Curiosity and Persistence: Einstein’s insatiable curiosity and relentless pursuit of knowledge were key drivers behind his intellectual achievements. He never ceased to question conventional wisdom, challenging established theories and pushing scientific boundaries.

Einstein’s remarkable IQ test scale score highlights the impact of exceptional cognitive abilities on an individual’s achievements. However, it is important to note that high IQ alone does not guarantee extraordinary success. Einstein’s relentless dedication, passion for learning, and unique mode of thinking were equally significant factors in his groundbreaking scientific discoveries.
