One area of research, ethical decision-making, relies on conceptual models that describe the steps that are antecedents to ethical or unethical behavior. One model is the four component ethical decision-making model attributed to Rest (1986), which includes (1) awareness, (2) moral judgment (Kohlberg, 1969), (3) moral intent and, (4) moral behavior. This constellation of components forms the basis of most ethical decision-making studies (Barnett & Vaicys, 2000; Jones, 1991; Kelley & Elm, 2003; Trevino, 1986; Trevino & Youngblood, 1990). This model is displayed in Figure 1. The first component, awareness, provokes the initial step in ethical decision-making. Highly nuanced, complicated, or ambiguous situations of individual experience must first be identified as having ethical relevance in order to activate the decision-making process. Pardales (2002) refers to making this first step as the capacity to perceive moral issues, exhibited as an issue enters individual awareness.

The second component in this model of ethical decision-making process is moral judgment, an unconscious and cognitive evaluation made by individuals depending on the level or stage of their moral development. Theories of cognitive moral development, described by Kohlberg (1969) and Rest (1986), explain how levels of moral reasoning evolve over a lifetime and have been found to be linked to education level and age.
The interaction between moral judgment and moral development has been studied variously, with authors attempting to measure the level of moral judgment by identifying hierarchical stages of development of the individual. The results of this research, called stage theory, are questionable, as the findings correlate level of moral development with age and education. According to Krebs et al. (1991), the explanation that the level of moral development increases with education fails to explain variation in judgment among educated, mature adults, demonstrating how research on the level of moral judgment seems to have limitations.
