I know there is someone on here that knows more about the actual nitty gritty details, but this is my take away.
Â
IQ and knowledge are different.
Â
IQ testing exposes kids to knew information, puzzles, and other 'new' information. They then are compared on how they learn, use, remember, apply, reason with, and connect those details. Other things are also tested- speed, vocabulary,etc that are influenced by exposure (such as knowledge of words to make an analogy). A child that knows how to compare and contrast items, may score a 'false' low if they do not know what the actual objects being compared are--but they are not lacking in the ability, rather in exposure. There are also checks and balances in IQ tests that go into a complicated formula to determine a final IQ score. But you can not 'study' for an IQ test. Then a child/person is compared to how other children that age do on the same test. The score is given in IQ- to put it simply. Most of the population have an IQ between 85 & 115. So a child could have a very high IQ and a low knowledge base.Â
Â
A child can have an average IQ and a high knowledge base.
Â
Â
IQ is actual cognitive ability (as best as we can measure it---different IQ tests can result in different numbers and IQ can vary: usually you are given a 'range' along with a firm number. The 'range' of numbers (say 120-130) is usually a 90% confidence rate that that persons IQ is between those numbers if they were given the same test again. The firm number is the number on that given day.
A high IQ does not always equal good grades or success. A child can have learning disabilities and still have a high IQ. A child can have a high IQ and do well in school or poorly. IQ has genetic and early brain development components. Â They (they being researchers) think that early exposure and a supportive and vocabulary rich environment can boost a childs IQ to certain degree by making stronger and more neural connections (not the actual knowledge itself, but the exposure to varied environments and ideas). IQ scores of young children ( under 7) are a hot debate in most educational circles and often deemed unreliable/inaccurate ( for being both too high and too low) due to the developmental growth/communication/ ability to be tested accurately and the wide variance that a few different answers/timing can make on testing scores when children are very young.Â
Â
Â
Achievement is how well academically a child does. It measures knowledge. Students that 'know' a lot often score high on achievement testing and do well in school. Achievement is also often rated by grade levels or percentiles. ( student is at a 3.4 reading level or a 3.1 math level-  or percentile 98% for age  or in the 65% in math skills, etc). With studying/practice/change of teaching style/exposure you can raise your achievement scores dramatically. Students with high achievement often have average, high average, or gifted IQs.Â
Â
A student with a large difference in IQ and achievement may have a learning disability. For example a student that has a 110 IQ-- but when  achievement testing in reading  and math and get scores of reading = 66 and math = 100. They would be seen as having a reading disability. There is a great gap (usually a 15pt or more spread or 1.5 to 2 standard deviations) between their ability levels and their actual achievement that causes them to have below average achievement.
Â
That said--- with a 100 IQ a child will have somewhat scattered achievement scores naturally, but they all should fall 'around' their ability level. All of us have strengths/weaknesses in certain areas and IQ does not automatically mean you will achieve that level of academic success.
Â
I have seen kids with 'low end' IQs do well academically and vice versa, kids with high IQs ( and no learning disabilities) do just OK at school.
Â
Generally- IQ numbers of a child tend to stay the same and achievement scores raise as the child gets older and gains more knowledge.
Â
A person has to have specialized training to administer and interpret  IQ testing (often an educational psychologist) Most teachers have some training to administer various achievement tests (depending on the test). As a former Special Education teacher I administered  A LOT of achievement testing- both traditional (running records, AR, DIBELS, etc) and specialized (KeyMath, Woodcock Johnston, etc).Â
Â
Different internal motivations, different interests, different learning styles, etc.
Â
That said-- also kids with high visual learning styles do better in schools academically because schools are geared toward visual learners ( lots to read and visually copy/write, etc). Â A child that is an auditory learner or kinesthetic learner may have a lot of knowledge and a average or high IQ and still struggle in school since their 'method' of learning does not fit with the way information is presented or taught.
Â
Gifted kids also tend to have a lot more 'unequal' Â development. Social skills may be age appropriate, but they are academically advanced. Physical skills may be advanced, but language skills are at or below expected for age, etc. Some gifted kids are 'globally' gifted and seem to accelerate ALL developmental skills ahead, but many many of them will develop in uneven patterns- sometimes even with alternating strengths and sometimes a strong acceleration/advancement in one area that always stays strong (math, reading, language, physical skills, etc).
Â
Schools are doing more to reach ALL learning styles, but a lot plays into what you know, how you learn it, and how quickly/how you apply it.
Â
* different schools often rely on DIFFERENT measurement tools to determine giftedness for 'educational programming'. Some areas require gifted level IQ (via group testing or individual), some go by achievement testing, others use both or a combination and/or alternative resources. There is not a federal mandate for Gifted Education. Some states do have mandatory gifted programming, others do not, some have explicit instructions on how gifted kids are taught and offer Gifted IEPs (GIEP), others have absolutely no support....so just keep that in mind depending on the area you are in when looking toward public schooling of your children*
Â

Does that help? I have worked with a lot of kids (teacher), but it has been a while since I brushed up on on my IQ and achievement testing- some things have changed in recent years in the field of both psychological testing/evaluation (IQ) and achievement testing. I do find it fascinating though. =]
