Currently, primary health care requires highly qualified human resources to address simple and complex health problems. Therefore, future nurses have the challenge during their training to consolidate professional competencies that allow them to meet the demands of the care of the person, family and community in an environment of prevention and promotion. The purpose of the study was to determine the level of knowledge, procedures and attitudes of nursing students in primary care at a university in Northern Lima. The methodology applied was quantitative, descriptive, cross-sectional and non-experimental design. Ninety-four students from the last cycle of nursing participated. A CPA scale was applied (Knowledge, Procedural and Attitudinal) with 45 questions with a Likert scale and its reliability of 0.86. The results show that 79% of students reached a level of achievement in theoretical knowledge, while 21% are in process. In terms of procedures 87% always manage to acquire skills, abilities and 13% are in process, and with respect to attitude 89% managed to strengthen this area and 11% was still in process. It is concluded that the majority of the students manage to consolidate knowledge, procedures and attitudes. However, it is necessary for the teacher to apply strategies to reinforce knowledge during the nursing care process in order to empower him/her as a nursing student in preventive and promotional care aimed at the person, family and community in a healthy or sick condition.
