本文首採電話訪談方式，普查宜蘭縣各國民中小學教師校外交通導護輪值運作情形及其後續補休的實施概況；其次，以法釋義學的觀點，探討上開部分學校創設的補休作法之適法性，然「依法行政」與機關首長的「行政裁量」之競合、教師「早自習」與「交通導護」兩者之加班對待歧異「體系內正義」的失衡、公教兩人事法令「體系間正義」扞格之諸關係，卻也突顯導護補休立異作法的可議性；最後，根據結論所得，提出本文建議：（一）教師卸下校外交通導護，致力校園教學與輔導工作；（二）因應公教人事分流，制定教育人員保障法；（三）教師成績考核辦法修正草案不應逕將「導護」納入考核細項；（四）教師、學校雙方行協商「導護」事宜，繼以列入聘約，其後續補休配套，亦應例外地不受一般加班規定之制約；（五）學校提供服務「範疇」的再確認。謹盼以此供相關權責機關與人員參考之用。
