Which term refers to statistics tracking library service usage and impact?

• A. Engagement Metrics
• B. Family Literacy Events
• C. Promotional Effectiveness
• D. Surveys and Focus Groups

Answer: (A)

Engagement metrics are the way librarians quantify how people use services and what effect that use has. This set of statistics covers both usage data—like visits, checkouts, program registrations, and digital resource access—and outcomes that show impact, such as repeated use, longer engagement with resources, or improvements tied to library programs. It’s the best fit because it directly names the measurement of how users interact with services and what those interactions achieve, rather than describing a specific event, a marketing result, or a data-collection method. The other options describe events (family literacy activities), outcomes from promotions (promotional effectiveness), or generic methods for gathering opinions (surveys and focus groups), rather than the overall measurement category for usage and impact.
