Abstract: Under the background of the current digital transformation of education and the high-quality development of vocational education, the reform of practical teaching evaluation system in higher vocational colleges has become the key factor to cultivate high-quality technical and skilled talents. Under the guidance of value-added evaluation theory, this paper constructs a value-added evaluation index system of practical teaching in higher vocational colleges based on CIPP evaluation model, which covers four dimensions of teaching background, teaching resources, teaching process and teaching results, and scientifically allocates the index weight by using analytic hierarchy process (AHP). Taking the practical course of core skills training and testing of engineering cost major in a higher vocational college in Jiangsu as an example, the effectiveness of the evaluation system in dynamically tracking students'skill growth and optimizing teaching strategies is verified.
