Evaluation of intermediate titles, starting from the primary title, continuing education once a year, can not be interrupted. As for how many years, it depends on the education or working years required by the intermediate title. For example, a college degree usually takes three to five years, then your continuing education will take three to five years. If you don't have enough academic qualifications and require six or eight years of work experience, then your continuing education will take six or eight years. For details, please consult the local education bureau or the local personnel examination network. Thesis title, teacher, published, paper net, Grade 9.
