First of all, I'd check experience of working with young learners- I am dripping with qualifications but have no experience of young learners, so would probably be a poor choice. If you're living in the US, then your daughter will presumably be attending school there, so a knowledge of the requirements of the primary or secondary education system would be very important. These are the most important things that I would be looking for. I'd also ask them to show the kinds of materials they plan to use and have a look through them.
