Hi, Valentine. From my previous research on relationship marketing, I think I might be of assistance to you with this question.

First, I think you should decompose your variables, then use the specifics to formulate your objectives.

Relationship marketing, in the school context could be decomposed into:

(1) Student-teacher trust

(2) Student-teacher communication

(3) Students' care service

(4) Students' welfare commitment

(5) Students' conflict resolution

(6) Quality educational service delivery

(7) Staff competence

Select any 3 or 4 of these variables to formulate specific objectives for your research. Regards.
