There is an NCAA-Men's case play that defines the beginning of the shooting motion. It is more restrictive than NFHS, I don't know what the NCAA-W's language is:

Act of Shooting
A.R. 120. A1 is dribbling the ball and attempts to turn the corner at the top of the key to drive down the lane. B1 fouls A1 as A1 picks up his dribble. A1 then steps with his right foot and then pushes off with his left foot before beginning to raise his arm(s) or hand(s) to release the ball for a layup. The try is successful.

RULING: The foul occurred before the act of shooting began. Therefore, the goal should not count. Charge B1 with a personal foul and shoot appropriate free throws if Team A is in the bonus. The language of 5-1.10, “The try starts when the player begins the motion that normally precedes the release of the ball,” refers to the hand(s) or arm(s) in preparing to release the ball on a try for goal. Examples of the act of shooting motion include raising the ball with the hand(s) and or arm(s) to shoot a layup or jump shot or the downward motion of the hand(s) or arm(s) in completing a dunk or alley-oop play. This act of shooting motion does not include picking up the dribble, catching (gathering) the ball, or advancing on the court with one or both feet. (Rule 5-1.10 and 4-8.1)
