School statistics may give a rosy picture. Schools may enjoy high ratings/rankings. Some of this may be attributed to practices such as grade replacement, and other means of raising the grades (if not the performance) of kids at the bottom.

Meanwhile gifted students may be thriving in spite of the school/district/teachers/policies/practices, not because of them. For example, a child who is bored in school may then spend time after-schooling in an area of interest. The knowledge gained in this endeavor, utilizing personal time, may then result in a high standardized test score, or ACT/SAT score, or other academic award/accomplishment for which the school/district/teacher will be glad to usurp credit for the child's performance.
