A computerized attendance system is presented that includes immediate access to attendance records and allows same-day notification to parents of a child's absence. The system, used at Carson City High School (Nevada), is broken down into five chronological steps, generating several possible attendance updates during the day: (1) compiling a first-period attendance list, (2) entering absences into the computer and calling parents to confirm absences, (3) reporting possible truants on a "hot list" sent to the office during periods by classroom teachers, (4) notifying parents about possible truancies, and (5) requiring an admit slip when a student returns from an absence. Printouts of absence lists for an individual class and for the entire school are included, as are samples of a first-period absence form, a "hot list," and an admit slip. Two appendixes present Carson City High's tardy policy and a flow chart of the computerized attendance system. (JW)
