This study tests the hypotheses that the relationship between being known by high school personnel and higher levels of well-being and a higher GPA is mediated by higher levels of school connectedness. Participants (n = 120) from Introductory Psychology courses completed surveys that assessed their perception of their high school faculty relationship(s), school connectedness, social/emotional well-being, and their grade point average. School connectedness was found to be a mediator between being known by high school personnel and well-being, but it was not a mediator for GPA. The typical relationship between school connectedness and GPA was found. This study is unique in that the relationships between school connectedness, being known by school faculty, social/emotional well-being, and GPA has not been tested within a single study that uses a population of college students who are reflecting on their high school experiences.
