How can a conference paper publication be guaranteed? Is such a "guarantee" even possible? My cousin, a freshman in college, recently heard from a private education institute that a conference publication will be guaranteed if she joins their research tutoring program. In their program description, they mention that their student will be promised to have their paper published in Scopus indexed conferences.

This intrigued my curiosity- how can someone promise that a college student who has never done any research before will be granted a conference publication? I don't think they would dare to write the paper on behalf of the student. 

So here comes my question - how can a conference paper publication be guaranteed?
It isn't that difficult. All that happens is that a private university pays an association (IEEE or something else) to host a conference. Then since they host it, they can choose to publish conference proceedings, with a journal sponsor. That is how most special issues work.
