I worked for Commonwealth Connections for several years. The job was wonderful UNTIL politics began to creep in. The best part of the job was interacting with the families. The worst part of the job was dealing with upper management which didn't listen.
There is compensation such as a "bonus" but you don't get it until the beginning of the following year for work completed. Again the families are wonderful. The teachers do their best under increasing demands.
If you are a hard worker, and don't mind minimal compensation, than this is the place for you. Otherwise you will work hard, late nights and if you don't find work/life balance you will burn out.
