Counseling psychologists have been instrumental in advancing a social justice agenda within the larger field of psychology. What is still missing within this agenda, however, is a fully developed consideration of classism within the spectrum of oppressions more commonly addressed in discussions of social justice and multiculturalism. The operations of classism can be difficult to see in a society that has long considered itself to be classless, and for counseling psychologists to undertake this work, they must initiate a deliberate effort to develop their awareness of classism as it affects their theory, research, and practice. In support of this end, the author presents a social justice conceptualization of classism, provides examples of classism at work, and outlines the resulting implications for counseling psychology practice.
