I'm trying to help my teenage daughter do a research paper for school. Can anyone identify what this topic means "Family Social class status: Implications for family relationship, education, an career success."

To me its implying the results of a family relationship, their education status and career success based upon the 4 social statuses. Is this correct? Give me much feedback as possible to get a clear understanding.

I would say it wants to know how family social status effects each of those 3 areas of a family life.
Example, how does family status effect a persons education.

What is the 4th social status you refer too? You only gave 3.

Take what you KNOW and ask her what she knows.
A paper like this has no correct answers, so enjoy it.
Family? Poor, uneducated parents may be lacking in a certain accent and the large vocabulary associated with highly paid careers.
Education? In many areas all over the world, a good education in childhood may only be available to the richer families, with exceptions, and a lot of help from caring parents.
Careers? Networking for careers can depend a lot of who you know and who your parents know, how you dress and talk and carry yourself, no matter how many degrees you have.

Those are very tiny examples. I didn't write her paper.
