The interrelationship between theory and practice in the field of Management Accounting is necessary and appropriate. From this perspective, this paper presents our experience in the Educational Innovation Project entitled Teaching and Business Practice in Management Accounting, through which we intend to establish a bridge between the subject teaching and business practice, through visit to the companies, where students had the opportunity to compare the applicability and usefulness, in the business practice, of the management systems discussed in class. In this Educational Innovation Project we have combined master class with complementary practices, through the tutorial method, the discussion led and case method. Using the tutorial method we have tried to individualize the process of learning students in small groups. This method has been completed with visit to the companies. Into the results highlight the contribution made to the development of certain skills, personal and interpersonal, among pupils, who have also shown greater interest in the acquisition of knowledge in the subject, which is reflected in their grades. Also, the participating teachers had the opportunity to approach the specific problems that arise in practice. Finally, it is remarkable the satisfaction achieved by students and teachers involved in the Project
