This is the highest level of Little League baseball, with teams comprised of primarily 11 and 12 year old children. On a highly limited basis, including a skills evaluation and specific parental consent, a small number of 10 year olds may be considered eligible to play on a major league team. These teams are assembled using a confidential draft selection process, using pooled skill evaluations to maximize equality. Players remain on the same team from year to year, until their little league eligibility ends. There is a post-season championship tournament that ultimately leads to the Little League World Series in Williamsport.
