Does PSU look at SAT writing?

Yes, it’s even used for placement!
“ENGLISH COMPOSITION – Your skill in writing, as assessed by the SAT-Writing Test, determines placement in the first-year English composition course. All Penn State degree programs require English composition, and ENGL 015 is the standard composition course. Students with strong preparation may take an honors composition course instead. Students whose SAT-W scores suggest gaps in their writing skills may need some review before taking ENGL 015.”
