Solid advice from
@MamaBear5 and
@socalkdg. I would add that there are some primary differences between the process for GK's vs field players:
1. GK recruiting often happens much later than field players. Not unusual at all for things not to fall into place until late in HS, even last semester of senior year. Partly, this is because the physical maturation necessary to really gauge a keeper takes time (see socalkdg's dd). And partly because the keeper situation from school to school can be so fluid and unpredictable that coaches often don't know what their keeper depth will look like for a given fall season until spring of that year or even later. Because playing time is so scarce, back-up and bench keepers will quit or transfer rather than go through the grind without faith that they will play, making a coach suddenly very interested in your kid at the last moment. Given the fact that field players are expected to play multiple positions, this isn't such a dramatic problem when one of them leaves.
2. Often, the HC is less involved in recruiting your keeper than they would be field players (unless the HC is a former keeper). At programs with dedicated keeper coaches, the keeper coach may be the primary recruiter. However, don't get too attached to a particular coach, especially an assistant or keeper coach as those jobs are HIGH turnover. The coach who primarily recruited my DD at her college was gone before she even started freshman year, and I've tracked the tenure of the coaches at 4 of the other schools that recruited my kid, and only one of them has retained both their HC and keeper coach from that recruitment cycle.
3. Video will be important because often, especially if your kid plays on a very good team, the coaches that come to see them play won't get to see a lot of action. The 2 schools that my DD narrowed down to at the end and gave her good offers watched her in person a few times, but I don't think she had one decent save opportunity in any of them. Still, they will want to see your kid in game to understand their presence, leadership, & communication ability.
4. Although ball handling/foot skills are becoming more important even in the college game, most colleges still play very direct, so punt & kick distance will still be a priority for most. And because most of their opponents play that way as well, a HUGE item for them is seeing a keeper being able to dominate in the air when crosses come into the 18 & 6 yard boxes. Crucial in the college game.
My last piece of advice for a keeper parent gearing up for the recruitment process is to be patient. If you kid sticks with it, there WILL be opportunities.
My DD's advice to all HS players looking to play in college is: "WORK YOUR ASS OFF. You have no idea how hard this is going to be."
