If you are interested in participating in FIRST LEGO League or FIRST Tech Challenge, it is highly recommended to start you own team. If you find two coaches and minimum of three team members, you can guarantee that your child is a part of a team. But, of course, this is not always possible.
FIRST recommends using the forums to seek assistance in finding active teams accepting members. Another option is to pitch the FIRST programs to your child's school or local organizations that your child attends (Boy Scouts, YMCA, Youth Clubs, etc...) with the use of information located at the link below.
