Display items from a category RSS from one WP site on a different WP site

I’ve been digging around the documentation regarding RSS for categories, but I’m a little lost as to how to proceed to get what I need.

We have two WP sites that serve as portals, one for faculty/staff and one for students. Most of the info and content is different, except there is one post category called “semester files” on both sites and they contain the same info. Currently a staff person posts the very same stuff to both sites.

Seems to me there ought to be a way to display the fac/staff category listing on the student site. First effort was to add a menu item link from the student site to the fact/staff site. This works, except it “puts” the student into the face/staff portal and then they are confused why the menu items are different, etc. so I want to have a page, inside the student site which displays the contents of the fact/staff category.

Am I write, I do that by using php code like -php post_comments_feed_link(‘RSS 2.0’); –
but containing the correct RSS info? Is the entire code like *ttp://www.example.com/category/categoryname/feed
go inside the ( )?

Am I headed in the right direction? The category name has a space in it. Is that an issue?

Any help appreciated. THX
