To get a more accurate idea of how your daughter compares to other swimmers, click on the link below and then download the PDF file titled "2009-2012 A/B Age Group Motivational Time Standards". You'll be able to tell if you are a "BB", "B, "A", "AA", "AAA, etc. swimmer. http://www.usaswimming.org/DesktopDefault.aspx?TabId=1488&Alias=Rainbow&Lang=en-US
After 30 years of coaching kids from 5 year olds to a few Olympians, High School All-Americans, National Age group record holders and finally at a Division 2 school in the NCAA, I'd suggest that thinking about a college swimming career for a 10 year old is a bit premature. There will be many changes in her life and choices over the next 8 years (almost 1/2 of her current life), especially when she gets to be about 14. Always keep in mind that, as a parent, you are a cheerleader and the source of her motivation must be intrinsic. Your job is to go to meets and support her ... champion her successes and comfort her (without saying you did "good" or "it will get better") when she does poorly as she knows if she did well or not. Say things like, "your stroke looks like you changed it" ... or, "boy your last length was really fast" or, "I don't care how you did, I'm proud of you".
When the time comes, be logical about making choices. When people think of collegiate swimming, they usually think of Division 1 schools and scholarships. But, D1 times are CRAZY FAST! Keep your mind open to a D2 school as D2 schools also offer scholarships. D3 schools also offer swimming but do not give scholarships.
