Newly graduated nurses show lacking skills and competences regarding the ability to make appropriate clinical assessment of acute, complex care situations. There is also a lack of translated, qualitative relevance evaluated and reliability tested rubrics in the Swedish language. The purpose of this method article was to translate, conduct a relevance evaluation and reliability test of the identified Lasater Clinical Judgment Rubric (LCJR). In this article the Swedish translation LCJR (S) is presented. The results showed that the LCJR (S) was both  qualitatively relevant and quantitatively reliable. We claim that there are several advantages to systematic use LCJR (S) for assessment of nursing students' clinical judgment in laboratory simulation environments with acute patient situations
