Introduction: A key aspect of teaching is analyzed in the framework of Higher Education that is student satisfaction with the completion of Final-Year Degree Projects (FYDP). Method: A longitudinal study is conducted over three academic years on student satisfaction with FYDPs. The study involves a sample of 1331 students, 1014 undergraduate students, and 217 master's students following 30 degrees projects and 23 master's projects. The objectives of this study are as follows: 1) To find the indicators of reliability and validity of the Satisfaction Scale; 2) To test whether significant differences exist in relation to the two variables 'type of studies' and 'type of discipline'; and, 3) To study the proposals suggested by the students for improvements to their FYDPs. Results: With regard to the first objective, the indicators tested with Confirmatory Factorial Analysis (CFA) were high (a = 0.88; a = 0.90) both for reliability (a = 0.88; a = 0.90) and for validity. With regard to the second objective, significant differences were found for student satisfaction in relation to both variables on all items of the Scale, except for general satisfaction. In relation to the third objective, the indicators of improvement consisted of optimization of planning and tutoring. Discussion and conclusions: Future training actions consisted of a training plan for teachers that considered the actions detected for improvement, as well as their follow up in a proposal for continuous improvement.
