The aim of this study was to develop a tool for the evaluation of the learning process of the clinical practicum in primary care. The study was carried out in two phases: (1) identification of the categories that determine the perception of the nursing degree students about the learning process in the clinical practicum in primary care and the items for each category; and (2) cross-sectional study in a sample of 475 nursing degree students. The psychometric properties in terms of reliability (internal consistency) and construct validity were analyzed through a confirmatory factor analysis. Cronbach’s alpha coefficient of internal consistency for the entire questionnaire was 0.93, and that for each of the categories was above 0.70 in all cases. The chi-squared test was statistically significant (2.84; p < 0.001). The confirmatory factor analysis produced a model of 6 dimensions and 41 items. The parameters were estimated through the least squares method. All saturations were statistically significant (p < 0.05). In view of the results of this study, it can be asserted that the questionnaire to measure the perception of the nursing degree students about the learning process in the community clinical practicum (QPCLP) presents good properties in terms of internal consistency and validity.
