Those “new” guidance counselors are still qualified… far more than most 17 year olds. He or she has applied to, been accepted to, and actually attended college, and has taken the necessary coursework. The he or she very likely beat out a host of other applicants for the job.
So I would be a whole lot more hesitant to condemn this person who has a world of experience you’re still hoping for.
In my school the College Placement Guidance counselor writes a letter for each one of his/her kids. Figure ballpark 120 or so.
