Driving rota
A 14-week rota where each family drives between 3 and 4 times, weighted so the family with 5 seats drives slightly less often but carries more each time.
How the Carpool Coordinator works
- List families with how many seats each can offer, since capacity is what determines how many drivers each week needs.
- Choose the balancing basis — turns is simplest, seats provided is fairer when capacities differ a lot.
- Share the rota early and agree the swap rule up front, because swaps are what actually break a carpool.
FAQ
How should fairness be measured?
By turns if cars are similar, or by seats provided when they differ — a family with a large car carrying five children is contributing more per trip than one carrying two.
What about families who cannot drive?
Agree it openly at the start, with a contribution in another form if the group wants one. The arrangements that fail are the ones where nobody said anything and resentment built quietly.
How do swaps work?
Whatever the group agrees, decided before the season rather than during it. A rule that a swap is between the two families involved and simply recorded avoids most of the friction.
