Step up does not provide the full qualification, it is only 14months and you would need to continue to complete a full masters which may or may not be funded so although it's great in a way, it's not in that it doesn't actually qualify you. Frontline takes longer but provides funding and the full qualification. There's also think ahead if you are interested in mental health at all. I would not do the normal masters if you can help it as I have heard of people struggling to find employment after it.
