Tinto's (1993) theory of student persistence (first edition published in 1987) is among the most widely cited theories in the field of higher education and has been described as reaching "paradigmatic stature" (Braxton & Lee, 2005, p. 108). Yet despite the promi nent contributions of Tinto's theory in understanding the student departure process, the theory has also received criticism. In a recent review of the conceptual and empirical critiques of Tinto's theory, Guiffrida (2006) asserted the need for the theory to recognize the impact of student motivational orientation on student persistence decisions. As Stage (1989) noted, Tinto's theory places a strong emphasis on student commitment but fails to describe the motivational orientations that lead to academic commitment. In his recent, comprehensive review of college retention research, Reason (2009) also highlighted the need to better understand relationships between student motivation and academic outcomes to increase our understanding of the college persistence puzzle.Guiffrida (2006, 2009) argued that the principles of selfdetermination theory (SDT; Deci & Ryan, 1991) provided an opportunity to advance Tinto's (1993) theory by recognizing relationships between motivational orientation and college student academic achievement and persistence. SDT is a theory of motivation, personality, and development that proposes that intrinsic motivation, or motivation derived purely from the satisfaction inherent in the activity itself, is more conducive to learning than extrinsic motivation, or motivation to achieve an external reward or to avoid a punishment. According to SDT, there are three primary psychological needs that, when satisfied, foster intrinsic motivation: (a) autonomy, which occurs when students choose to become engaged in learning because the subject and activities are closely aligned with their interests and values; (b) competence, which is the need to test and challenge one's abilities; and (c) relatedness, which is the need

Although relatedness is posited to be a distinct need in itself, relationships often (but not always) provide the context in which the other two needs can be satisfied. SDT considers that motivation falls along a continuum, with more external forms of motivation at one end and more internal forms of motivation at the other, and that needsatisfying experiences can help to shift motivation from the external to the internal end of the continuum (Ryan & Lynch, 2003).Numerous studies have tested key SDT constructs in both labbased and classroom settings, leading it to become one of the most empirically validated theories for understanding educational motivation (see Reeve, Deci, & Ryan, 2004), and evidence is beginning to emerge that supports its relevance for education crossculturally (e.g., Chirkov, 2009). However, the theory has not been applied extensively to understand college student academic achieveme...
