Any business certification programs that are worthwhile? (Maybe pre-MBA or MA/PhD?)

<p>D is graduating in 2013 with a degree in international studies. She is thinking that she might like to pursue a degree in international trade eventually, but her undergrad courses (at an LAC) have focused on the politics of international relations, and she has not taken any business classes (no business department; she has taken two semesters of introductory econ).</p>

<p>Are there any certification programs that might help her understand more about what business school or international trade is about?</p>
