Purpose: Apply the educational software Fuzzy Kitten with undergraduate Brazilian nursing students.
Methods: This software, based on fuzzy logic, generates performance scores that evaluate the ability to identify defining characteristics/risk factors present in clinical cases, relate them with nursing diagnoses, and determine the diagnoses freely or using a decision support model.
Findings: There were differences in student performance compared to the year of the course. The time to perform the activity did not present a significant relation to the performance. The students' scores in the diagnoses indicated by the model was superior (p= .01).
Conclusions: The software was able to evaluate the diagnostic accuracy of students.
Implications: The software enables an objective evaluation of diagnostic accuracy.
