Abstract: Establishing a scientific practice teaching evaluation system is an important way and a solid guarantee to improve the effectiveness of practice teaching of ideological and political theory course in medical schools. CIPP evaluative theory is a comprehensive evaluation for practical teaching activities in terms of content evaluation, input evaluation, progress evaluation and product evaluation, which has a strong fit with the practical teaching evaluation of ideological and political theory course. With the help of CIPP evaluative theory, the teachers of ideological and political theory can reasonably identify the problems in the existing practice teaching evaluation system. Therefore, through enriching the evaluation content, optimizing the evaluation subject, strengthening the process evaluation, as well as improving the evaluation method, the configuration of the evaluation elements can be further perfected. In addition, the evaluation system of practical teaching in medical schools can be more scientific, systematic and continuous.
