All the tryouts are for is to determine if your daughter is on the A, B, or C team and so on. Select soccer is all about the $$$$. If you are willing to pay, there is a spot for you daughter on the team. Most clubs charge between 650-1000 to play club + travel expenses. Depending on the club, you may go to two or three out of town/overnight tourneys and can plan on spending $300-500 for the weekend. Most clubs make the team members pay any entry fees + pay for the coaches hotel, in addition to their own expenses. You can plan on easily spending $2500 a year to play select soccer. All coaches at the select level must be licensed to coach.
Here are the clubs I know about:
Ankeny/Iowa Rush - The Rush is a national organization who took over a few years ago. This is a very political league, and have lots of turnover in players and coaches. The select teams typically practice 3 times a week. Games are played on the weekend, and they do a lot of travel. Plan on weekend trips to Cedar Rapids, Iowa City, Minneapolis and possibly Kansas City. My niece and nephew both play/played and they do a lot of travel. Example, my niece went to CR and played on two games on a Sunday at 1:00PM and 5:00PM, can make for a long day when you factor in a two hour drive. They have the best fields in the metro IMO. One note about Ankeny, their boys team that won the state tourney a few years ago, NEVER played select soccer in Ankeny. They played Recreational and stuck together as a team instead of being shuffled around each year which is very common in select.
Vision Soccer Academy (Waukee) - my kids play here. They travel some of the least of any of the metro clubs. They stress fundamentals in the 9-10 age group and really push them at 11 into select. VSA has the worst field location of anyone in the metro, in the middle of the country, on a gravel road, and always 10 times more windy than in town. As the kids get older, there is some grooming for the Waukee school district kids toward the high school level. Select teams practice 3 times a week.
West Des Moines - do a lot of travel to odd places. They have gone to Indianapolis, St. Louis, Detroit, Champaign/Urbana for weekend tourneys. They play at Hidden Valley which is at Walnut Woods State Park. It used to be known that at U15, the Valley coach would come in and help select teams because he was basically setting them up for high school soccer. Don't know if that is the case, but was rumored by many.
Des Moines Menace/Soccer West/Grimes - just starting their girls select program this year. They've had boys select for several years. They play at 63rd and Grand in Des Moines. Several DSM Menace players are coaches. I have been told they lack technical skills, and believe this after my daughters team played their this past weekend, and the Menace team struggled to get the ball past the 1/2 line.
Johnston/Urbandale - they are combined for select. Don't know much else about the program.
All these programs play in the Iowa Premier Soccer League, so they can play all over the state as I mentioned.
