This study aims to explore the construction of an evaluation index system for undergraduate engineering majors based on the Context, Input, Process, Product (CIPP) model under the Outcome-based Education (OBE) approach employing the Delphi method and Analytic Hierarchy Process. The trial of the evaluation index system involved 986 entrepreneurs, engineering technicians and teachers majoring in the field of electronic-information, who were recruited and selected for participation on the Internet. Data were collected from the consultation questionnaire developed in accordance with the indicators at all levels. Subsequently, Principal Component Analysis was used to verify the rationality of the indicator design, and the corresponding weights were adjusted. The results found that the index system includes 4 first-level, 11 second-level, and 42 third-level indicators, and different weights are assigned according to the extent of influence each of these indicators has on the quality of undergraduate training. Furthermore, the evaluation system can reflect the actual relationship among the indicators to some extent, which provides reference for the quality evaluation of engineering education.
