Background: Changes in demographics and the development of health systems have a direct impact on patients' nursing needs and nurses' ability to meet them. Modern and forward-looking nursing education programmes that will help nursing students to develop their professional competence require useful tools for assessment and self-reflection that can be combined in theoretical and clinical education.

Objectives: To investigate the associations between the Nurse Professional Competence Scale – Short Form (NPC-SF), and the tool Assessment of Clinical Education (AssCE) tool, and to assess the graduating students´ professional competence based on their self-assessment.

Design: A cross-sectional descriptive study design was used.

Participants and settings: A total of 151 nursing students at a Swedish university college completed the NPC-SF and the AssCE (response rate 77%).

Methods: In their final weeks of the nursing programme, students were invited to respond to two questionnaires: the NPC Scale - Short Form (35 items) and the AssCE tool (21 items).

Result: There are significant correlations between the nursing students' responses to the NPC-SF competence areas and the AssCE areas (r = 0.19–0.57). Students score in the NPC-SF were highest in Value-based Nursing Care and lowest in Development, Leadership and Organization of Nursing Care, and in the AssCE areas student scores were highest in Examination and treatment and Professional Approach and lowest in Management and Cooperation.

Conclusion: The NPC-SF and AssCE are valid and reliable instruments, showing a high level of correlation. Results imply that dual use could strengthen student-centred theoretical and clinical learning as well as professional competence development. Additional research is needed to assess student's competence development during the nursing program.
