Gather information from a Mastersheet to individual worksheets - pending selection

I cant figure out how to do this.

I have a Master list of kids names and age groups, that will be used by Coaches to update, from this i would like to have each of the different age groups details extracted into different worksheets within the same workbook.

I used an IF statement to but found it was leaving blank lines between finds.

I have attached the spreadsheet - any help or hints or alternative methods are welcomed.
