I tried to avoid slandering top boarding schools with the "especially after first grade and before high school". I am a byproduct of such a boarding schooling. The quality of the teachers was high, and academically you don't comprehend the gap until you reach college and realize a majority of your classmates can't write, only read for required assignments, but were in the top 2% of their school, and graduated with a gpa 1.0 higher than yours. That said, I have also met a number of well prepared students from public schools (and a large number of poorly prepared students who spent $120,000+ on their high school education, but didn't take advantage of it). I am a fairly strong believer that the real distinction is within the students (as necessitated by my desire to maintain my self-worth). The most successful students, at any institution, will be those who are self-motivated, have well educated and intelligent parents, a well educated peer group, and are intelligent themselves. These are the confounding factors I mentioned. Students with parents who have terminal degrees are more likely to be attending these elite institutions. This parental advantage may be the strongest influence in intellectual development, and thus clouds the value of private schools. In addition the wealth of the students attending these schools is much higher than at a public school (its weird when your school has children whose parents are billionaires). This wealth provides numerous more resources for students: tutors, summer classes, camps, et al. These addition resources provided by surplus wealth also confound the true value of these high-end schools. Counseling programs do vary by school, but my experience is not particularly unusual for a higher end private school. These schools will typically have 100% of their students accepted to a school when they graduate. That doesn't happen by accident.
