Assess early learners' understanding of common community helpers (police, firefighters, nurses/doctors, paramedics, sanitation workers, crossing guards, librarians) and public services, focusing on how each role and service keeps neighborhoods safe and healthy. Include tasks that identify helpers and tools, match helpers to responsibilities, explain simple cause–effect relationships (e.g., trash removal prevents disease; firefighters stop fires), and analyze short, age-appropriate scenarios to choose the right helper. Designed for Pre-K–Grade 2 with moderate reasoning and explanation.
