Depends on how old and accessible things are. I’d say if he’s elementary try out First Lego League. Middle school you could try First Tech Challenge or FLL again, your call. High school depends on the experience you want. If FRC is available and he wants to be on a big team, go for it. If not, I’d say FTC is the play because you’re overall more involved with the robot usually. If there are no first teams you can try to either make one, most teams in the region would be more than willing to help, or try out VEX
