In general, the ITGT is suitable for anyone at any age as it is able to provide a valuable insight for people at any stage of career, emotional or personality growth. However it is most recommended for children below the age of 21, where they have many more life choices ahead of them. Also, the younger the age, the better the probability that the parents may be able to mould the character of the child and prevent him/her from falling for some of the potential pitfalls in his/her natural dispositions. In addition, parents are able to give the child a head start by developing his/her talents early in life. For maximum effect, parents may consider performing this test for their newborns.
