It varies and many critical factors count for IQ level.

As mentioned, all children Intelligence Quotient (IQ) is same. Their way of responding, understanding, reciprocating and communicating slowly changes which is dependent on the surrounding atmosphere and environment after an age of about 10 years.

Not necessarily.

Thank you Jasim Hassen for your reply to discussion. Can you please elaborate your words above, so that I can learn and understand?

Of course not! The average IQ of people is changing over time. The older you are, the more stable your test score will be. For children, cognitive intelligence varies from one to another.

Not the same.

Thank you Hassan Izzeddin Sarsak for your answer. Amal Saadoon Majeed would you please tell me, how it is not the same? I am eager to hear...

Dear Pisipaty Srinivas Kishore

IQ tests should be tailored to each child's personality. A shy child who loves isolation is different from a daring social child. The first needs to gain confidence and feel important then can express frankly what he thinks.

Thank you Amal Saadoon Majeed for your answer.

I think all the children have same intelligence quotient (IQ). The circumstances and environment changes their attitudes and their behaviour in turn reflects in their concentration and slowly their IQ changes.

Children at early ages, may have same intelligence coefficient (IQ). This changes as age goes up. Attitudes of children, environment, friends, house hold and education may change IQ of children and cannot be constant.

It's not same

I think it should be, then their environment should dictate or direct the rest!!

It varies and many critical factors count for IQ level.

Thank you Abbas J. and Difo Voukang Harouna for your answers.

No. Even brothers and sisters has different abilities and different understanding.

Thank you Basheer Raddwan for your reply.

They have different IQ as per their field/area/zone of liking

Thank you Mahavir Balmukund Varma for your reply.

Dear Pisipaty Srinivas Kishore ,

I do not agree that all children start from birth with the same cognitive abilities, as you said in your initial statement. I'm quite sure that there are genetic influences on IQ and furthermore, prenatal effects like e.g. hormone level or nutrition supply will contribute to the mental capacity.

Thank you Thomas Neusius for your view.

No. Just think about their mathematical skills. Differences in mathematical skills among 10-year old children are very large, and IQ is closely related to mathematical skills.

Thank you Peter Moinar for your answer.

I think Intelligence quotient (IQ) is same for all children, up to a certain age. The level of understanding, behaviour, attitude and environment changes their IQ levels as years pass. After a certain age, one can see the change in perception and mindset of a child.

Most children reach the same level of complexity at about the same time, but some of them are slower reaching those levels.

Thank you Safaa Kadhem for your answer.

I believe, Intelligence Quotient (IQ) is same for all children at their younger ages. They all do what their parents or friends say. As the age goes up, each one behaves and goes in their way of thinking.

Thank you Terry Purvis for your answer.

IQ is not same. There are several factors, which effect on IQ level.

No it is not the same between the children. among the brother how carried the same genetic factor there is differences.

Intelligence Quotient (IQ) varies in all children.

Thank you Abbas J. and Zainab Mahmood Jawad for your answers.

Thank you Nirmala S.V.S.G for your answer.

Intelligence Quotient (IQ) is different in children.

Thank you Abbas J. for your answer.

IQ differs varies in all child even if it varies between children of same parents. It is genetically and environmentally influenced traits. Such as feeding components, behavioral traits and genetic expression are among factors responsibility for this variation.

Thank you Peter Ayodeji Idowu for your answer.

Intelligence Quotient (IQ) is different in the children.

Thank you Abbas J. for your answer.

I agree with @ Thomas Neusius, not all children have same IQ from their birth. Lots of other factors play big role for developing intelligence before and after birth.

Thank you M.M. Mahfuz Siraz for your answer.

By birthday, IQ is not identical in kids all over the world. Intelligence Quotient (IQ) is different in the children of even same parents.

Thank you Chaojie Jin for your answer.

In my view, Intelligence Quotient (IQ) for children are same. The reason being, they come to unknown environment, make familiar themselves and think. This takes time. Gradually children attitudes be changing, their living environment and constraints also adds their IQ to change. For some, the change be less and for some, the change be more.

There is a large amount of factors that we bring on this world in the moment of birth. IQ isn't the same for all kids - just compare twins - it's very rare that they have the same IQ.

Thank you Dijana Vučković for your answer.

In September 2019 the US NIEHS released its draft report stating that Fluoride is now "presumed to be" a Neurotoxin with simlar properties to Lead. Please see the attached figure.

Dear Geoff Pain , to connect the finding you posted with the discussion: The figure gives an example how the IQ can be altered disadvantageously in a population by exposition to neurotoxins. As a consequence, even very young children may exhibit varying IQ values, as they were heterogeneously exposed to such chemicals. Potentially, such influences arise even before birth.

That fits in my previous argumentation: IQ is not equal among all children, not even upon birth.
