At the most basic level, needs assessment is about identifying the gap between “what is” and “what should be.” The needs assessment process is used to set priorities for programs and allocation of resources. It is based on the assumption that a given community or population will have more needs than can be met with existing resources, and setting priorities is critical. Although much of the literature on needs assessment focuses on identifying needs, it is important to recognize that a comprehensive approach includes conducting a capacity assessment. This involves identifying assets within the community that will support efforts to address needs. While the very definition of a needs assessment emphasizes the use of an objective approach to identifying needs, it must be acknowledged that it is also a subjective and political process. For example, who is consulted to identify needs? Whose needs are they? How are “needs” defined? Who judges the importance of needs? How do we account for cultural differences? Needs assessment is one of the first steps involved in planning a program. Although there are a variety of approaches described in the literature, models for needs assessment involve a systematic process that includes focusing the study, collecting and analyzing data, identifying areas of need, setting priorities, identifying solutions, and evaluating the needs assessment. Common themes associated with a successful process are highlighted in various models of needs assessment: (1) engaging stakeholders to participate and inform the process, (2) using multiple methods to collect data (e.g., surveys, existing records, interviews, observation), and (3) setting priorities. Many authors affirm that needs assessment should be an ongoing and continuous process since communities and the environment in which they exist are constantly evolving.

Introductory Works

Available online for community action groups or people who are new to the area are several practical resources, such as the Centers for Disease Control and Prevention 2010, Cavanaugh and Chadwick 2005, Work Group for Community Health and Development 2007, and Health Canada 2000. Wright, et al. 1998 offers a concise description of what needs assessment is and why it is important. McKenzie and Smeltzer 2009 provides a general introduction to the steps in a needs assessment. Altschuld and Kumar 2010 gives a detailed overview and guides practitioners through each phase of conducting a needs assessment.
