Explain one advantage of using IQ tests.

Tests such as the Wechsler Scale, where the items range from very easy to very difficult and so are not age related, are useful because they allow a wide range of abilities to be tested. This is not the case with more simple educational assessment tests. Because it has items for different types of intellectual abilities, the Wechsler Scale is more useful for diagnosing learning difficulties. For example a child could have a very high verbal and general score but a low reasoning score, and this indicates that the child may have a specific problem with reasoning. This child could then receive special help with improving their reasoning abilities. These tests are also useful for identifying the child who is far above the norm for their age. This gifted child will also have special needs and help would be provided to enable them develop to their full potential.

IQ tests are a great advantage in identifying children with unusual gifts and learning difficulties at an early age. They can then receive the special care and attention they need to develop their abilities fully.
