I should have posted verbally committed. Actual committed doesn't happen until a player signs a letter of intent February of their HS Sr year.
If you have a DD that has a lot of individual soccer accolades. She will be evaluated by college coaches her freshmen year in HS and receive offers her sophomore year. If your DD elects to pass on Power 5 school offers, they will move on to the next player on their recruiting list. Many Power 5 schools are already extending offers and receiving verbal commits from 2019 players.

If Ivy League is the destination then yes, Jr and in some cases Sr year is when the player will verbally commit.
As for grades, my DDs head coach asked for a copy of her freshmen grades and every semester afterwards. This way they can keep track of her academic progress. The college coaches have been doing this for years, so they already have a good idea what is needed to pass admissions at their university.
