George — I don’t know how old that specific breakdown is, but roughly those criteria have been in use for at least a decade. My junior year of high school, I was rejected because despite participating in extracurriculars, I didn’t have “leadership” positions in any of them. No matter that the particular activities I was involved with — math team, band, etc. (yes, I was that much of a geek) — didn’t even have leadership positions for students.
