A student should typically take an IQ test once every few years. Frequent testing isn't necessary as IQ scores remain relatively stable over time. For most children, taking an IQ test around the ages of 6-8 and then again during adolescence can provide valuable insights into their cognitive development. If specific concerns arise, such as significant changes in academic performance, additional testing might be warranted. However, it is essential to consider the purpose of the test and consult with educational professionals to determine the appropriate timing for reassessment.
