Learn what IQ scores mean and how they're categorized. IQ classification is the practice by IQ test publishers of labeling IQ score ranges with category names such as "superior" or "average".

Once you understand these scores and how they fit in a bell curve, you can better understand the different categories of giftedness. Why is a score between and considered mildly gifted? Why is a score between and highly gifted? The answer lies in the standard deviation of the scatter of IQ scores on the bell curve. The standard deviation used in many tests, including the Wechsler IQ test, is Most scores are somewhere between 85 and Those scores are considered the "average" or normal intelligence range.
The farther the score is from , the fewer people we will find with that score. Roughly 2. People often want to lump all gifted children into a single group, assuming that all of these children have the same needs. Nothing could be farther from the truth. A good way to understand the difference in the needs of these different groups of children is to consider how far they are from the norm of If you look at the scores for each group, you will notice that each category represents one standard deviation from the norm.
To understand the difference one standard deviation can make, consider the scores below One standard deviation on either side of is within the normal, or average, range. Move down one more standard deviation and you move into the range of borderline intellectual functioning 70 to Children with scores in this range qualify for special academic services.
Moving down another standard deviation takes us into the range of mild intellectual disability 55 to The farther a child's score is from the norm, the more they will require special academic services. Now move in the opposite direction of An IQ score up to one standard deviation above is considered normal, or average. Move up one standard deviation and you are in the mildly gifted range. That means that a child with a score of is as different from a child with an IQ of as is the child with an IQ of 80, a score which qualifies a child for special services.
Move up one more standard deviation and we move into the range of moderately gifted to The same range on the other side of is the mildly intellectually disabled range. No educator would believe that every child with an IQ anywhere below 70 needs the same academic services that every other child in the range would need. The standard deviations below are meaningful.
They are no less meaningful when they are above IQ testing is not an exact science. It may seem that way at times, but it's not. Scores from tests are really estimates based on someone's test performance on a particular day.
There is always a margin of error. The "actual" score could be higher or it could be a little lower, though it's somewhere within the margin of error. However, it is also important to note that the score won't change substantially. That is, a child who gets a score of did not get that score because she had a "good day. An average child cannot get a score that high just because they ate a good breakfast and felt good that day. While IQ tests tend to group children into certain categories, it's important to remember that each child is different.
It's also best to keep in mind that IQ scores are not designed to be a predictor of a child's accomplishments, now or in the future. While you might be excited or disappointed with the results, try to keep them in perspective with your child's overall development and individual learning needs.

In plain sight but still invisible: a structured case analysis of people with mild intellectual disability or borderline intellectual functioning. In this method, an IQ score of means that the test-taker's performance on the test is at the median level of performance in the sample of test-takers of about the same age as was used to norm the test.
An IQ score of means performance one standard deviation above the median, a score of 85 performance, one standard deviation below the median, and so on. By the current "deviation IQ" definition of IQ test standard scores, about two-thirds of all test-takers obtain scores from 85 to , and about 5 percent of the population scores above Lewis Terman and other early developers of IQ tests noticed that most child IQ scores come out to approximately the same number regardless of testing procedure.
All IQ tests show a slight variation in scores even when the same person takes the same test over and over again. Even before IQ tests were invented, there were attempts to classify people into intelligence categories by observing their behavior in daily life. Both intelligence classification by observation of behavior outside the testing room and classification by IQ testing depend on the definition of "intelligence" used in a particular case and on the reliability and error of estimation in the classification procedure.
IQ tests generally are reliable enough that most people 10 years of age and older have similar IQ scores throughout life. Terman recruited school pupils based on referrals from teachers, and gave them his Stanford—Binet IQ test. Children with an IQ above by that test were included in the study.
There were children in the main study group. When the students who could be contacted again students were retested at high school age, they were found to have dropped 9 IQ points on average in Stanford—Binet IQ. More than two dozen children dropped by 15 IQ points and six by 25 points or more. Yet parents of those children thought that the children were still as bright as ever, or even brighter. Because all IQ tests have error of measurement in the test-taker's IQ score, a test-giver should always inform the test-taker of the confidence interval around the score obtained on a given occasion of taking each test.
In cases of test-giver mistakes, the usual result is that tests are scored too leniently, giving the test-taker a higher IQ score than the test-taker's performance justifies. Some test-givers err by showing a " halo effect ", with low-IQ individuals receiving IQ scores even lower than if standardized procedures were followed, while high-IQ individuals receive inflated IQ scores. IQ classifications for individuals also vary because category labels for IQ score ranges are specific to each brand of test.
The test publishers do not have a uniform practice of labeling IQ score ranges, nor do they have a consistent practice of dividing up IQ score ranges into categories of the same size or with the same boundary scores. IQ classifications from IQ testing are not the last word on how a test-taker will do in life, nor are they the only information to be considered for placement in school or job-training programs. There is still a dearth of information about how behavior differs between persons with differing IQ scores.
The lesson here is that classification systems are necessarily arbitrary and change at the whim of test authors, government bodies, or professional organizations. They are statistical concepts and do not correspond in any real sense to the specific capabilities of any particular person with a given IQ. The classification systems provide descriptive labels that may be useful for communication purposes in a case report or conference, and nothing more.
There are a variety of individually administered IQ tests in use in the English-speaking world. When a test-taker scores higher or lower than the median score, the score is indicated as 15 standard score points higher or lower for each standard deviation difference higher or lower in the test-taker's performance on the test item content.
The Wechsler intelligence scales were originally developed from earlier intelligence scales by David Wechsler. The first Wechsler test published was the Wechsler—Bellevue Scale in Like all current IQ tests, the Wechsler tests report a "deviation IQ" as the standard score for the full-scale IQ, with the norming sample median raw score defined as IQ and a score one standard deviation higher defined as IQ and one deviation lower defined as IQ Psychologists have proposed alternative language for Wechsler IQ classifications.

Terman believed his test measured the " general intelligence " construct advocated by Charles Spearman Terman chose the category names for score levels on the Stanford—Binet test.
When he first chose classification for score levels, he relied partly on the usage of earlier authors who wrote, before the existence of IQ tests, on topics such as individuals unable to care for themselves in independent adult life. Terman's first version of the Stanford—Binet was based on norming samples that included only white, American-born subjects, mostly from California, Nevada, and Oregon. Rudolph Pintner proposed a set of classification terms in his book Intelligence Testing: Methods and Results.
The second revision of the Stanford—Binet test retained "quotient IQ" scoring, despite earlier criticism of that method of reporting IQ test standard scores. A data table published later as part of the manual for the Third Revision Form L-M of the Stanford—Binet test reported score distributions from the second revision standardization group. David Wechsler , developer of the Wechsler—Bellevue Scale of which was later developed into the Wechsler Adult Intelligence Scale popularized the use of "deviation IQs" as standard scores of IQ tests rather than the "quotient IQs" "mental age" divided by "chronological age" then used for the Stanford—Binet test.
Wechsler also criticized the practice of earlier authors who published IQ classification tables without specifying which IQ test was used to obtain the scores reported in the tables. In , Wechsler published another edition of his book Measurement and Appraisal of Adult Intelligence. He revised his chapter on the topic of IQ classification and commented that "mental age" scores were not a more valid way to score intelligence tests than IQ scores.
For rough comparability of scores between the second and third revision of the Stanford—Binet test, scoring table author Samuel Pinneau set for the median standard score level and 16 standard score points for each standard deviation above or below that level. The highest score obtainable by direct look-up from the standard scoring tables based on norms from the s was IQ at various chronological ages from three years six months with a test raw score "mental age" of six years and two months up to age six years and three months with a test raw score "mental age" of ten years and three months.
David Freides, reviewing the Stanford—Binet Third Revision in for the Buros Seventh Mental Measurements Yearbook published in , commented that the test was obsolete by that year. The classifications used by the WJ-R Cog were "modern in that they describe levels of performance as opposed to offering a diagnosis.
Wechsler changed a few of the boundaries for classification categories and a few of their names compared to the version of the test. The test's manual included information about how the actual percentage of persons in the norming sample scoring at various levels compared to theoretical expectations. It retained the deviation scoring of the third revision with each standard deviation from the median being defined as a 16 IQ point difference. The S-B IV adopted new classification terminology.
After this test was published, psychologist Nathan Brody lamented that IQ tests had still not caught up with advances in research on human intelligence during the twentieth century. The earliest terms for classifying individuals of low intelligence were medical or legal terms that preceded the development of IQ testing.
Medical doctors sometimes encountered adult patients who could not live independently, being unable to take care of their own daily living needs. Various terms were used to attempt to classify individuals with varying degrees of intellectual disability. Many of the earliest terms are now considered very offensive.
In current medical diagnosis, IQ scores alone are not conclusive for a finding of intellectual disability. Recently adopted diagnostic standards place the major emphasis on the adaptive behavior of each individual, with IQ score just being one factor in diagnosis in addition to adaptive behavior scales, and no category of intellectual disability being defined primarily by IQ scores. Virginia , U. Francis Galton — was a pioneer in investigating both eminent human achievement and mental testing.
In his book Hereditary Genius , writing before the development of IQ testing, he proposed that hereditary influences on eminent achievement are strong, and that eminence is rare in the general population. Lewis Terman chose " 'near' genius or genius" as the classification label for the highest classification on his version of the Stanford—Binet test.
Catherine M. Cox, a colleague of Terman's, wrote a whole book, The Early Mental Traits of Geniuses , published as volume 2 of The Genetic Studies of Genius book series, in which she analyzed biographical data about historic geniuses. Although her estimates of childhood IQ scores of historical figures who never took IQ tests have been criticized on methodological grounds,    Cox's study was thorough in finding out what else matters besides IQ in becoming a genius.
The Terman longitudinal study in California eventually provided historical evidence on how genius is related to IQ scores. Two pupils who were tested but rejected for inclusion in the study because of IQ scores too low for the study grew up to be Nobel Prize winners in physics: William Shockley   and Luis Walter Alvarez. Charles Spearman, bearing in mind the influential theory that he originated—that intelligence comprises both a "general factor" and "special factors" more specific to particular mental tasks—, wrote in , "Every normal man, woman, and child is, then, a genius at something, as well as an idiot at something.
A major point of consensus among all scholars of intellectual giftedness is that there is no generally agreed upon definition of giftedness. In practice, many school districts in the United States use an IQ score of , including roughly the upper 2 to 3 percent of the national population as a cut-off score for inclusion in school gifted programs.
Five levels of giftedness have been suggested to differentiate the vast difference in abilities that exists between children on varying ends of the gifted spectrum. As long ago as , Lewis Terman pointed out that error of estimation in IQ scoring increases as IQ score increases, so that there is less and less certainty about assigning a test-taker to one band of scores or another as one looks at higher bands.
All longitudinal studies of IQ have shown that test-takers can bounce up and down in score, and thus switch up and down in rank order as compared to one another, over the course of childhood. Some test-givers claim that IQ classification categories such as "profoundly gifted" are meaningful, but those are based on the obsolete Stanford—Binet Third Revision Form L-M test.
Although two current tests attempt to provide "extended norms" that allow for classification of different levels of giftedness, those norms are not based on well validated data.

The narrow definition of IQ is a score on an intelligence test Some of the implications are that: 1. Approximately two-thirds of all scores lie between 85 and Similarly, five percent are below 75 and one percent below Studies of individuals, on the other hand, may reveal large upward or downward shifts in test scores.
When we use these terms two facts must be born in mind: 1 That the boundary lines between such groups are absolutely arbitrary, a matter of definition only; and 2 that the individuals comprising one of the groups do not make up a homogeneous type. To a large extent they were practical attempts to define various patterns of behavior in medical-legal terms. Adapted with permission. Even though not all studies indicate significant discrepancies between intelligence batteries at the group level e.
Interestingly, while his tests measured decreases in test scores, the parents of the children noted no changes at all. Of all the parents who filled out the home questionnaire, 45 percent perceived no change in their children, 54 percent thought their children were getting brighter, including the children whose scores actually dropped. The confidence interval is a function of both the standard error of measurement and the confidence level: the greater the confidence level e.
The most conservative view would be that IQ is simply an ordinal scale: to say that someone has an IQ of is simply to say that their test score lies within the top 2. Follow the specified classification system strictly, labeling scores according to what is recommended in the test manual. If you believe that a classification does not accurately reflect the examinee's status, state your concern in the report when you discuss the reliability and validity of the findings.
IQ tests are not intended to isolate and measure highly specific skills and knowledge. This is the job of suitably designed achievement tests. ISBN Terman and Merrill , pp. Wechsler deserves credit for popularizing the deviation IQ, although the Otis Self-Administering Tests and the Otis Group Intelligence Scale had already used similar deviation-based composite scores in the s.
In most cases the reporters proceeded to interpret the I. The examiners were seemingly unaware of the fact that identical I. Wells 32 years ago in The Mental Measurements Yearbook. The Binet scales have been around for a long time and their faults are well known.
Moreover, IQ measures are less valid in the lower end of the IQ range. It is of course obvious that much error may creep into an experiment of this sort, and the I. Generally, the more information, the higher the IQ. Subjects were dragged down if there was little information about their early lives. So she proceeded to make a statistical correction in each case for lack of knowledge; this bumped up the figure considerably for the geniuses about whom little was in fact known. I am rather doubtful about the justification for making the correction.
That all equally intelligent children do not as adults achieve equal eminence is in part accounted for by our last conclusion: youths who achieve eminence are characterized not only by high intellectual traits, but also by persistence of motive and effort, confidence in their abilities, and great strength or force of character.
Seventy—seven who were tested with the newly translated and standardized Binet test had IQs of or higher—well at or above the level of Cox's geniuses. What happened to these potential geniuses—did they revolutionize society? The answer in brief is that they did very well in terms of achievement, but none reached the Nobel Prize level, let alone that of genius.
It seems clear that these data powerfully confirm the suspicion that intelligence is not a sufficient trait for truly creative achievement of the highest grade. Yet a few decades later that talent received the Nobel Prize in physics: William Shockley, the cocreator of the transistor. Ironically, not one of the more than 1, children who qualified according to his IQ criterion received so high an honor as adults.
According to Hastorf, none of the Terman kids ever won a Nobel or Pulitzer. Despite their exclusion from a study of young 'geniuses,' both went on to study physics, earn PhDs, and win the Nobel prize. The probable error in terms of mental age is of course larger with older than with young children because of the increasing spread of mental age as we go from younger to older groups.
For this reason it has been customary to express the P. However, when our correlation arrays [between Form L and Form M] were plotted for separate age groups they were all discovered to be distinctly fan-shaped. Figure 3 is typical of the arrays at every age level. From Figure 3 it becomes clear that the probable error of an I.
It has frequently been noted in the literature that gifted subjects show greater I. In these cases, errors of measurement for scale scores will increase substantially at the extremes of the distribution. Commonly the SEM is from two to four times larger for very high scores than for scores near the mean Lord, Although spreading out the test scores in this way may be helpful, the corresponding normative scores i.
