Abstract: In order to train audit professionals to meet the needs of the new era, aiming at the problems existing in the construction of the traditional course team, and taking the first-class undergraduate course construction as an opportunity, the audit demonstration course team was established. After nearly three years of team building practice and exploration, remarkable results have been achieved. Practice has proved that strengthening the construction of demonstration course teams based on the construction of first-class undergraduate courses can not only improve the teaching ability and level of the entire course team, but also can promote the continuous improvement of the construction of first-class courses, effectively improve the quality of undergraduate teaching and help the construction of first-class majors.
