My daughter went through half a dozen pre reads over the summer at D3 schools for another sport. Admissions took anywhere from a day to a week. Results were communicated from admissions to the coaching staff and coach contacted my daughter with the outcome.
While she passed all the pre reads, not all coaches came back to her with an offer. A couple invited her for an official overnight visit in the fall, one stalled (we assumed she was not a priority recruit and Coach was waiting for a higher priority athlete to turn the spot down before making her an offer).
All offers received were contingent on applying ED1 and maintaining academic and athletic performance.
