To assess changes in program participation across years, which method would you use?

• A. Attendance at programs.
• B. Longitudinal trends.
• C. Student Demographics.
• D. Underserved Communities.

Answer: (B)

Tracking participation over multiple years is best understood through longitudinal trends. This approach repeatedly measures the same variable—program participation—at different points in time, so you can see how it rises, falls, or stays steady year by year and identify patterns or shifts. A single-year attendance snapshot only shows a moment in time, not how participation changes. Demographics tell you who is participating, not how participation changes across years, and discussions of underserved communities focus on groups rather than on tracking change over time.
