IQ is an acronym for 'Intelligence
Quotient', is a total score derived from several standardized tests designed to
assess human intelligence. IQ score is obtained by dividing a person's mental
age score, obtained by administering an intelligence test, by the person's
chronological age, both expressed in terms of years and months. The resulting
fraction is multiplied by 100 to obtain the IQ score.
IQ scores are used for educational
placement, assessment of intellectual disability, and evaluating job
applicants. Even when students improve their scores on standardized tests, they
do not always improve their cognitive abilities, such as memory, attention and
speed.

IQ TESTING
IQ tests come in many forms. They
can help diagnose intellectual disabilities or measure someone’s intellectual potential. If you’re considering IQ testing, your
doctor should be your first point of contact.
An IQ test may be the first step
in diagnosing intellectual issues. If your child has a particularly low score,
Your doctor may also order other tests accompanying with IQ tests. These tests
include; Adaptive skills screening, Blood tests, Brain ultrasound, Full mental
health screening and Prenatal screenings.
Prenatal screenings may help to
detect potential intellectual disabilities before babies are born. This is
especially the case for mothers who are 35 or older, or those who have used
drugs or alcohol during pregnancy. If potential issues are detected at this
time, your pediatrician may follow up with an IQ test in early childhood.
Intelligence quotient 'IQ' can be
calculated by having the person take an intelligence test. The average IQ is
100. If you achieve a score higher than 100, you are smarter than the average
person, and a lower score means you are less smart.
Types of IQ tests
There are a variety of
individually administered IQ tests in use worldwide. The most commonly used
individual IQ test series is the Wechsler Adult Intelligence Scale for adults
and the Wechsler Intelligence Scale (Wechsler Individual Achievement Test) for
Children for school-age test-takers. Other commonly used individual IQ tests
includes the following;
1. Stanford-Binet Intelligence
Scale
2. Universal Nonverbal
Intelligence
3. Differential Ability Scales
4. Peabody Individual Achievement
Test
5. Woodcock Johnson III Tests of
Cognitive Disabilities
History of IQ testing
French psychologist Alfred Binet
lived in France, during his period (in 1880s) he noticed that many children in
school were struggling, but he didn't think it was due to lack of intelligence.
So Binet made a very important distinction between two different things that
might lead to poor school performance.
He said that some children will do
badly because they simply aren't intelligent, so there's not much that can be
done to directly help them improve their grades. However, he said that other
children have plenty of learning ability and potential to do well, but they
struggle simply because of life circumstances.
Also Binet said that these
children, who have a high learning ability, should be distinguished from
children who do badly in school because of low intelligence.
In the early 1900s French
psychologist Alfred Binet created the first intelligence test. However, modern
IQ testing in the United States stems from the work of Henry Herbert Goddard.
Goddard was a psychologist who earned his doctorate in psychology from Clark
University in 1899. He translated the Binet test from French to English. This
test was used to test basic intellectual functions in U.S. school children and
to support mental health diagnoses.
How to Get an IQ Test
IQ tests still remain inaccessible
to many families, not all public schools use them. Some families may not have
access to a doctor or psychologist who can administer the test. This can lead
to missed opportunities for crucial testing especially during a child’s early years when treatment is
vital.
Today i will show you how to get
an IQ test by using Alfred Binet test (Stanford-Binet Intelligence Scale)
Everyone has an individual
intelligence quotient 'IQ', which is a number indicating your inherent ability
to learn instead of simply the knowledge you already have. If you have a high
IQ, it means that you have the intelligence required to do well in school
because you have the ability or potential to succeed.
Alfred Binet said that the way we
can do to calculate IQ is to compare two things. First, we just need to know
how old a child is, which known as 'Person's chronological age'. What's your
chronological age? Right now I'm 33, so that's my chronological age.
Also Binet said that we need to
know your mental age, which is your cognitive abilities relative to what others
can do of different ages. Your mental age is what you are capable of doing,
scaled to what the average people of different ages can do. If you're capable
of doing what an average 23-year old can do, then your mental age is 23. If you
can do what an average 11-year old can do, but not anything more advanced than
that, then your mental age is only 11.
Now we have two scores;
Chronological age and Mental age, therefore we need to compare them. If you are
advanced, or very intelligent, according to Binet, then your mental age will be
bigger than your chronological age. Let say you are 22 years old right now, but
you can do what an average 30-year old can do, then you're 8 years ahead of
schedule, which Binet would say makes you very intelligent.
Also maybe you're 22 years old,
but can only do what the average 10-year old can do. Binet would say that you
are cognitively delayed and therefore not intelligent based on IQ.
The IQ Equation
Alfred Binet created an equation
so that we could calculate IQ scores easily that will indicates where we stand
in comparing these two scores. The equation is as follows;
Intelligence quotient (IQ) =
(Mental Age ÷
Chronological Age) ×
100
We make a ratio of the two ages
(Mental and Chronological ages), with mental age on top, and the only reason we
multiply by 100 is to get a nice, round number instead of a fraction.
To understand well how to
calculate IQ scores, checkout the following examples;
Example 1
If your mental age and
chronological age are a perfect match, meaning you've Mental age: 22 years and
Chronological age: 22 years, the results are as follows;
IQ = (Mental age ÷ Chronological age ) ×
100
= (22 ÷
22) × 100
= 100
The results shows that IQ score is
100, meaning a person is exactly where the average person would be, so an IQ of
100 will always mean average intelligence for IQ.
Example 2
If a person is mentally advanced,
meaning you've Mental age: 30 years and Chronological age: 22 years, the
results are as follows;
IQ = (Mental age ÷ Chronological age) × 100
= (30 ÷ 22) ×
100
= 137
The results shows that IQ score is
137, it is higher than 100, meaning the person is more intelligent
than the average or extreme intelligent. There is a rumor that Albert Einstein had an IQ of 160!.
Example 3
Let's say we have a person who is
a little bit developmentally delayed, meaning he or she might have Mental age:
10 years and Chronological age: 22 years, the results are as follows;
IQ = (Mental age ÷ Chronological age) × 100
= (10 ÷ 22) ×
100
= 45
The results shows that IQ score is
45, it is lower than 100, meaning a person mental abilities are not as good as
the average person of his or her age group.
IQ test result
From the above examples, it shows
that we've three categories of IQ scores; Average score, High scores and Low
scores, Both these three scores have explanations below;
1. Average score
A score of 100 is considered
average.
2. High scores
A high IQ score over 100 is
typically associated with high intelligence. Extreme intelligence is 130 or
above.
3. Low scores
Lower scores below 100 is
considered to have “below
average” intelligence. Extremely
low scores, below 70, are usually a cause for concern. They may indicate an
underlying learning disability.

CONCLUSION
IQ scores can differ to some
degree for the same person on different IQ tests, so a person does not always
belong to the same IQ score range each time the person is tested. Therefore you
need to use different IQ test to identity person intelligence test, don't rely
on single IQ test.
