Abstract: Hong kong's primary and secondary school teachers' moral accountability system adopts an accountability model that is mainly based on school accountability and supplemented by off-campus accountability. It has established a complete professional training and moral evaluation system in primary and secondary schools, and has formed the system of accountability for primary and secondary school teachers with characteristics of multiple accountability subjects, professional autonomy of accountability objects, institutionalization and group participation of the accountability process. Drawing on the experience of teachers' moral accountability of primary and secondary schools in Hong Kong, mainland China should seek ways to improve the teachers' moral accountability system:(1) strengthening the pre-vocational training of non-normal school students; (2) strengthening the Empirical and scientific nature of the means of accountability; (3) paying attention to the accountability within schools; (4) improving the level of accountability services of education authorities.
