Passing standardized tests should be a natural byproduct of successful education. It should, by its nature, be a small sampling of the knowledge and understanding learned through the overall comprehensive education of a kid. You'd expect successful enrichment would naturally raise gifted kids performance into the advanced area or reinforce the underlying skills and abilities that already would.
Any directed attempt to teach to a standardized test is akin to putting lipstick on a pig. Is that their perception of the actual quality of the education they offer? Whether that's the intended message or not, there is definitely an underlying trend of gifted children taking their toys (high scores) away and going home to school.
