What does commensurate with vocational goals mean? Is the mother of the child still able to collect summer child support?

1. If the child changes majors three times which extends her education for one and a half years because of wasted classes she will not be using for the new major, is this commensurate and is she in violation of the rcw law?

2. If the child does not return home in the summer anymore because she lives with her boyfriend, is fully employable now using a CNA license, is the mother still able to collect child support?
