Without naming particular schools, there are few things to keep in mind regarding ID camps.
All ID camps are fundraisers so the invite list is quite large. Within that, are some real interests at times.
Just because its addressed to your particular child, I would not interpret that to mean its a personal invite from the coach. Many mail programs will address canned notes to individuals from their database. Some of these canned notes sound quite personal these days. If it has some additional attributes with the note (e.g., saw you play at XXX tournament, viewed your highlight videos, noticing grades and accomplishments, ...), then chances are that a coach did take some notice and is interested in finding out bit more about the player.
Some schools use ID camps almost strictly as money makers, whereas some actually find players and recruit from it. Its hard to know which is which but a good indicator is looking at a coach to camper ratio. Many schools invite other school coaches to the camp (their buddies) and they run the teams during the camp while the school hosting the camp actually scouts the players. Some schools run the camp only with their staff and limit the campers by capping the total players to maintain adequate ration. Then there are some that hosts as many as they can get over a couple of days.
Thank you for the good info!
The big consolidated camps run by a third party, where they invite coaches from 30~50 schools, typically ends up nothing more than an introduction to some of the attending coaches and they, in turn, invite the players to their own school's ID camp thereafter. That said, I know a case where the player met his coach of interest at one these big camps, and continued dialogues through the year until their ID camp came up and was greeted by the player first name when attending the institution's camp, resulting in a very positive feedback at the end to continue on.
The other thing to keep in mind is that the camp is simply an intro and liken to "first date", as it were. The courtship goes a long ways before anything is consummated into an offer. While shotgun deals may happen here and there, it is unusual and one probably should not expect it. Reason - many coaches been burned by flashy players and later regretted their decision. Good coaches will take their time and perform due diligence of the player and the family.
The college coaches are looking at everything at ID camps, such as work ethics, social interactions with other players during breaks meals and info sessions, conduct on the field during plays and so on. Not just soccer skills and abilities.
Last, most camps are not meant to be a development camp, but is an evaluation camp for their purposes. If you want any feedback, make a point to go talk to the coaches after the camp is over and often that will either close the door, or keep it open and to continue on further with the school. Keep in mind that it is just as important to eliminate schools from your list as the time go by so that one is not chasing everywhere. Go where you are wanted.....
ps, last last thing on this. We've setup a different email for academic correspondence versus soccer correspondence. My kid gets recruiting emails from all over the country, highly famous to never heard of schools, and fills up the inbox for academics. By using different email for soccer, you can keep track of which school is emailing for soccer or academics.
These are my takeaways from my kid and teammates doing few ID camps. YMMV....
