The effectiveness of existing services is evaluated through which of the following actions?

The effectiveness of existing services is evaluated through a comprehensive approach that encompasses multiple methods of assessment. Feedback from service users is crucial, as it provides qualitative insights into their experiences, satisfaction, and perceived outcomes. Understanding the user perspective is essential for identifying strengths and areas for improvement.

Routine audits by external agencies serve as an important form of oversight, ensuring that services adhere to established standards and regulations. These audits can uncover discrepancies in service delivery and highlight opportunities for enhancing quality and accountability.

Quantitative data analysis offers a systematic approach to evaluating service effectiveness through measurable indicators such as outcomes, attendance rates, and service utilization. This data can help social workers and organizations track trends over time and assess the impact of services quantitatively.

Since all these methods contribute valuable information and perspectives when evaluating service effectiveness, the answer encompasses the comprehensive nature of the evaluation process, making it the most accurate choice.
