Direct practice in social work constitutes one-on-one contact with people at the micro level and is usually identified as working with people directly at the individual, group, or family level. Rather than specifying a particular theory, direct practice is seen as an eclectic process structured by the problem-solving process with the guiding underlying principles of sensitivity to social diversity and promotion of social and economic justice. At the micro level, this most often involves bringing services to and improving the quality of life of people who are vulnerable and oppressed. However, direct practitioners must also be able to assess different systems levels beyond the individual and determine the appropriate intervention and its appropriate level (micro, meso, and macro), and to know when and how to implement various theories. This complex undertaking is not taught in a systematic way but rather is guided by the development of personal awareness, knowledge of social work values and ethics, sensitivity to social diversity, and promotion of social justice.
