“…For instance, rates of high school completion have been found to vary among ethnic groups (Hess, 1986;Rumberger, 1983Rumberger, , 1987Weidman & Friedmann, 1984;Young, 1982), academic ability levels (Cook, 1956;Kowalski 8c Cangemi, 1974;Livingston, 1958;Lloyd, 1976), region (Hill, 1979;Mare, 1980;Nam, Rhodes, 8c Harriot, 1986), and school setting (Hammack, 1986;Hess, 1986;Wehlage, 1983). Additional research has shown that dropouts tend to be older than their grade-level peers (Hess, 1986;Howell & Frese, 1982;Livingston, 1958;Lloyd, 1976), have a higher likelihood of coming from broken homes (Fitzsimmons et al, 1969;Howell 8c Frese, 1982;Rumberger, 1983), experience higher rates of academic failure (Bachman, Green, 8c Wirtamen, 1971;Biddle, Bank, Anderson, & Keats, 1981;Eckstrom, Goertz, Pollack, & Rock, 1987;Strother, 1986), and have experienced frequent moves and school transfers (Hammons & Olsen, 1988). Some research relates the propensity to drop out with a lower family socioeconomic status (Lerman, 1986).…”
