The thing is only about 1/3 of HSs rank anymore because ranking has fallen out of favor over the last decade or so.
Many high schools not only don’t provide rank, but they don’t publish other info that would allow an AO to infer rank (which AOs don’t have time to do for all applicants anyway)…for example, some counselors don’t complete the level of curriculum section in their counselor letter.
On the high school profile, some schools show a class median GPA only, some give a mid-50% range…deliberate obfuscation ensues here too because some schools will provide data for unweighted GPAs while the transcript has weighted GPAs (and these two GPA calcs use different sets of classes).
Most schools that still rank are private. Of course, most Texas publics still rank.
