The aim of this study is to evaluate the undergraduate curriculum of a nursing program in accordance with nursing students' and instructors' opinions by using the Context, Input, Process, and Product (CIPP) model. This is a descriptive study which was conducted between September 2017 and July 2018 with 448 students and 82 instructors of a faculty of nursing. The Student and Instructor Information Form and Nursing Undergraduate Curriculum Evaluation Form (NUCEF) were used in order to collect data. The NUCEF consists of 50 items under four sub-dimensions called the Context, Input, Process and Product. The obtained data were analyzed using the SPSS 20.0 program. The frequency, percentage, mean, and standard deviation tests were used in the data analysis. The level of satisfaction with the curriculum was found to be 4.47 +/- 2.09 for the students and 6.80 +/- 1.89 for the instructors. 42% of the students stated that they thought the program outcomes were not achieved, and 42.7% of the instructors stated they thought the program outcomes were partially achieved. When the distribution of responses of Context, Input, Process and Product sub-dimensions of the NUCEF was examined; the mean item score of the students was found to be between 2.27 +/- 1.15 and 3.83 +/- 1.06, and the mean item score of the instructors was found to be between 2.08 +/- 1.06 and 4.06 +/-.72. Considering all the sub-dimensions of NUCEF, students think that nursing undergraduate curriculum is partially adequate, and instructors think that nursing undergraduate curriculum is adequate. To conclude, it is recommended that the current undergraduate curriculum be reviewed and regulated, continuous and systematic program evaluation and improvement studies be carried out, and program evaluation studies in nursing education be increased.
