Background and Purpose: The clinical learning environment is the space in which nursing students develop their professional skills. The Clinical Learning Environment, Supervision and Nurse Teacher (CLES+T) scale makes it possible to assess its quality. This study aimed to develop the psychometric testing of the newly translated Catalan version of the CLES+T.

Methods: The translation process was carried out according to the principles of good practice of the International Society for Pharmacoeconomics and Outcomes Research Working Group. The students completed the Catalan version of the CLES+T, and 15 days later, they took part in the temporal stability test.

Results: The internal consistency was .934, and the interclass correlation coefficient of the re-test was .865. The exploratory factor analysis showed five dimensions.

Conclusion: The Catalan version of the CLES+T scale is a valid and reliable tool to assess the quality of clinical learning environments in Catalonia.
