The Social Science Research Methods Poster-Plus Session began in spring 2011 as an opportunity for students in social science research methods courses to present a course project. It has expanded it to include student posters from non-methods courses that require a social science research project, as well as independent studies and honors theses.

As of 2015, the session has also included multimedia presentations of social science research (short films, websites, etc.) in addition to posters — thus the title "Poster Plus."
