I completely disagree with the gatekeeping mentality on the reach schools. If student wants to give a $90 donation to GF’s-alma-mater-U by way of an application, then it’s no business of a guidance counselor (public or private) to stop them.
Should the kid ask for a glowing recommendation that would be less than truthful then the GC has the right to say no.
The GC, in taking salary from taxpayers or tuition payers, is obligated to do their job: warn the kid and his parents that it’s a reach (put it in writing if there’s a need to CYA), and send the transcript with the same LOR you sent to all his other schools (GC’s assessment of his chances at one school shouldn’t negate the good qualities written in regards to him for other schools). Charge a small $10-or-so “processing fee” for the transcript for the reach school if necessary (not a punitive amount - just something to hint, “You know you’re wasting our time, right?”). The HS GC is NOT the college’s AO.
