Which phase is focused on ongoing collection and analysis of information?

The phase that focuses on ongoing collection and analysis of information is evaluation. In this stage, practitioners systematically assess the effectiveness of the interventions they have implemented. This involves gathering data about the client's responses to treatment and overall progress towards their goals.

Evaluation is essential for determining whether the strategies and methods being used are achieving the desired outcomes. It allows social workers to identify any necessary adjustments or changes to the treatment plan based on the information gathered. This phase helps in ensuring that the interventions remain relevant and effective throughout the client's journey.

In contrast, the other options pertain to different stages of the social work process. Assessment is primarily concerned with gathering initial information about the client’s situation and needs, while planning involves the formulation of strategies based on that assessment. Intervention focuses on the actual execution of these strategies rather than ongoing evaluation. Thus, evaluation stands out as the specific phase dedicated to the continuous collection and analysis of information to monitor and enhance client outcomes.
