The REC Foundation has committed to ensuring that the top 30 teams in programming skills and top 30 teams in robot skills receive an invitation to the 2016 VEX Worlds. Teams that receive invitations through online challenges or state/regional qualifying will not be replaced in the skills challenge top 30, therefore there is no guarantee that teams ranked below 30 will receive an invitation. In addition, a team that ranks in the top 30 in both Robot and Programming Skills will be guaranteed an invitation, teams ranked outside the top 30 in either category are not guaranteed to receive an invitation. I hope that this clarifies the process. Good luck!
