A student writer has identified a weakness in the passage. A counseling access report proposes a brief triage call for students requesting urgent appointments. The writer includes a counselor's explanation of the process and one student's positive experience. The report still does not show whether average wait times changed for the larger group of students seeking care. The next sentence discusses staffing limits and referral options. Writer's note: “Before the final sentence, I need to measure the system-level effect without relying on a single account.” Which kind of support would address the remaining development gap most precisely?
