Do educational programmes need to be in italics within the Harvard system of referencing? I am mentioning  educational programmes within my essay and wonder if I need to have the name of the programme in italics? (For example, the Wellmother programme.)

Also I have mentioned a Government document, Midwifery 20/20 in the essay and wonder if this needs to be in italics?
In general, italics would not necessarily be used just to represent the name of something. You wouldn't write "the Marshall Plan", so you wouldn't write "Wellmother programme", either.

As for the government publication, that's a different matter altogether. If the document is a "stand-alone" publication, as most such works are, then it should be italicized as if it were a book. So, this could also extend to a program if it were announced as a formal document, rather than just a policy position.
