<p>If the HS is known to be rigorous and doesn’t rank then it doesn’t hurt the student even if the colleges are able to compute exactly where the student lands wrt to class rank because it doesn’t pollute their ranking/image.</p>
<p>But if the HS ranks then it certainly is unfair to student following the hardest curriculum and the school is unable to take that into account while ranking (i.e. not following a weight system)</p>
