To resolve the evaluation quality problems of higher vocational education, such as large evaluation workload of practice teaching, cumbersome statistical, the evaluation index system of practical teaching quality in higher vocational colleges is put forward. Based on a lot of the characteristics of fuzzy information during the teaching process, the fuzzy evaluation model of practice teaching quality is established. Using this model calculation, the research results show that this fuzzy model has better evaluation of results, and this method is simple in principle, feasible in process, reasonable in result and easy to operate and so on, compared with other methods. So this model is a valid method to analyze and calculate the field data.
