“…Hess (1998) reported that the majority of dropout intervention research was judged as low in methodological quality. In response to this concern and our desire to advance the degree to which school completion interventions are theoretically driven and scientifically based, we: (a) describe criteria specified by Crane (1998a), (b) apply the criteria to 15 intervention studies (Allen, Philliber, & Hoggson, 1990; Baker & Sansone, 1990; Catteral, 1987; Comiskey, 1994; Curiel, Rosenthal, & Richek, 1986; Dugger & Dugger, 1998; Einolf, 1995; Grannis, 1994; Jones, 1992; Mayer, Mitchell, & Clementi, 1993; Pearson & Banerji, 1993; Reyes & Jason, 1991; Sinclair et al, 1998; Stern, Dayton, Paik, Weisberg, & Evans, 1988; Vitaro, Brendgen, & Tremblay, 1999) to provide a baseline for intervention research, and (c) illustrate the use of the criteria with one intervention study.…”
