Taking the state demonstration construct key specialty "numerical control technique" of Chongqing Industry Polytechnic College as research target, this paper proposes a perfect model of self evaluation on campus. We also establish related index system and quality standards. By using the principle and method of fuzzy neural network, this paper establishes a comprehensive evaluation model based on FNN-ES, and gives a concrete Implementation of evaluation software based on VC++. This paper also presents a detailed process of employing manual evaluation's results on intelligent model's training and using. It uses matlab to validate and improve the performance of the FNN algorithm. The mature-trained intelligent system can be used for specialty assessment of mature specialty. Then it was spreaded to other colleges. The results of theory and practice researching show that FNN-ES for specialty assessment can overcome various human factors. It makes the assessment result more scientific, stable and reasonable. This system can provide guidance and basic data for off-campus specilty evalution of provincial and national level.
