As the study of student connection to school has expanded, so too has the lexicon of terms, concepts, and measurement tools. In summarizing the literature to guide current practice and future research, the various terms and definitions need clarification. The intent is not to settle on a single term, though agreed on language may benefit future research. The goal of this paper is to clearly identify the various terms, constructs, and instruments used. Table 1 lists the terms and variables used to measure a student's relationship with school. Terms were selected based on conceptual and component interrelatedness. Arguably, other terms may fit equally well. Terms were selected based on a similarity to the term connectedness or a definition similar to that of school connectedness. Measures will be described briefly followed by identification of the common constructs of the different variables. In this paper, "school connectedness" represents the term used to refer to the study of a student's relationship to school. (Contains 2 tables.)
