My kids school has 6.1% of students identified gifted.

Another school in the same state, 30 miles away, has a 44.3% of students identified gifted.

How could a school have nearly half of the students be identified gifted?

What I know about the district is that it’s highly desirable, in a higher socioeconomic area, a suburb of a big city. I expect families are mostly college educated and have high incomes. I do hear a little about kids being stressed because of feeling academic pressure.

Is it accurate? Or not? Is there any advantage to identifying more kids as gifted?
