There is no single IQ score that is considered "normal" for a fourteen year old. IQ scores can vary widely among individuals of the same age, and there is no one-size-fits-all answer. However, as a general guideline, an IQ score of 90-110 is considered to be within the average range. Scores above 110 are considered to be above average, while scores below 90 are considered to be below average.
It's important to remember that IQ scores are not a perfect measure of intelligence, and they can vary depending on the test that is used. Furthermore, IQ scores do not take into account factors such as creativity, emotional intelligence, or cultural background, all of which can contribute to a person's overall success and well-being.
