A psychoeducational report often shows two different kinds of scores. One set describes how a person reasons, solves problems, and works with information (cognitive, or IQ, scores). The other describes learned academic skills like reading, writing, and math (achievement scores). When these two do not line up, it is natural to ask what the gap means, whether you are reading your child’s report or your own. This guide explains what the comparison captures, the many ordinary reasons the two can differ, and what a gap does and does not tell you.
Quick Answer
A gap between cognitive and achievement scores is common, and on its own it is not a diagnosis. It is one pattern an evaluator weighs alongside history, observations, and other testing, never a conclusion by itself. A difference between two scores is also less precise than either score alone, so the size of a gap is only a starting point. What it means depends on the full profile, not any single number.
