Joint School District No. 2 Here are all of the listings currently available for the Meridian School District. You can also find a salary schedule on the left side. Be prepared to have a pay cut as a teacher if you come from a major city. I was making about $27K with a Master's Degree teaching High School. Unfortunately Idaho (much like the rest of the US) pays teachers very poorly.

Also be aware that depending on the state you are coming from, your wife will need to get certified in Idaho. Usually she will have to take a few extra classes which she can do while working. But it all depends on the certification she has now, some teacher just transfer their certifications. She will have to contact the Idaho board of education.
I hope this helps, Fab
