@ucbalumnus, thank you for sanity checking my comprehension; I scanned the abstract while sipping my coffee, and wasn’t planning on lifting the hood on the paper. I guess its main point is that correlation changes depending on the group being considered, which is somewhat interesting.
But, perhaps you could point me in the right direction regarding studies that show higher correlation of HSGPA to college GPA (vs SAT to college GPA). I only ran into Hiss’ study (the one from Bates - which is test optional).
The other article I saw was one from the College Board which is recommending using both GPA+SAT as the most predictive method as mentioned here earlier. However their charts show similar correlations for GPA and SAT. I was curious if their results were replicated elsewhere as well.

Re: other factors, I’m a fan of grit myself. Makes itself evident on the field, in the class room, in the workplace (and even in situations requiring care/sympathy). Curious if it is sufficiently represented in GPA or if we need these other metrics to gauge it properly…
