Here is another example: let’s say a child received a standard score of 110, with a 90% confidence interval range of 98-124. This means that with high certainty, the child’s true score lies between 7 and 9, even if the received score of 8 is not 100% accurate. Since a test cannot claim 100% accuracy of any score, the confidence interval claims strong accuracy based on a range of scores.įor example, let’s say a child received a scaled score of 8, with a 95% confidence interval range of 7-9. A confidence interval expresses to what degree a score is “guaranteed” to be accurate. To account for testing and human error, the scores described above are often offered alongside a Confidence Interval. Finally, the research around standardized testing acknowledges that the scores obtained from a child’s performance may not be entirely perfect.
