You or your daughter may call the coach at any time in her career.
And the coach/school rep may contact you or your daughter at any point UNTIL they are a freshman, that's when the NCAA views them as a bona fide potential recruit.
You also may visit the coach(es) at his/her campus and talk freely at ANY point in time. Until the official visit, however, all expenses are on the parent/recruit.
Of course, the college coach may contact the player's coach (assuming it's not mom/dad) at any point as well.
