One thing that came over loud and clear to anyone seeking employment in this tough-to-break-into field was the message, "Be persistent". Work on a student newspaper. Write your own blog. Even offer to make the tea (in exchange for being given five minutes to pitch your story idea). Take the initiative.
A useful website mentioned by Tony is that of the National Council for the Training of Journalists, which features a results section so that you can compare the results achieved by students of particular courses in different institutions.
