U.S. Presidential Scholars Applicants 2019

Hi everyone, thanks for starting the thread. Can you please explain to me the selection process? Is it purely based on SAT/ACT? My daughter got 35 on the ACT, and did not take the PSAT, does it mean she definitely won’t be selected as a candidate? Any other criteria? I also read that each state’s secretary of education nominates 10 girls and 10 boys, how does that happen? Do kids submit their names for nomination, or what? Thanks so much!
