Which step in the change process involves gathering and evaluating information to identify client needs?

The step in the change process that involves gathering and evaluating information to identify client needs is assessment. During the assessment phase, social workers collect various forms of data that may include client interviews, observations, assessments, and standardized tests. This comprehensive evaluation allows the social worker to gain a deeper understanding of the client's situation, strengths, challenges, and specific needs.

By meticulously assessing these elements, social workers can identify the appropriate interventions and plan subsequent steps in the change process effectively. This foundational work is crucial as it ensures that any strategies developed later are tailored to the unique circumstances of the individual or group being served.

In contrast, planning focuses on developing strategies to address the issues identified during the assessment, implementation involves putting those strategies into action, and termination pertains to concluding the professional relationship once goals have been achieved. Thus, assessment is distinctly characterized by its focus on understanding and defining client needs through careful information-gathering.
