I disagree that OP should look the other way. Why complain about cheating at all if we’re going to encourage children to ignore it? If OP speaks privately with the school guidance counselor, the guidance counselor can speak privately with the schools. S/he knows whose essay was used and what college it was submitted to, so it shouldn’t be too difficult for the GC to track down. I agree with T26E4; I hope s/he’s successful.
