In accordance to North American Nursing Diagnosis Association (NANDA), nursing diagnosis is a clinical judgement of the individual, family or community answers to the vital process or to the actual or potential health problems. These gives the basis for the intervention selection by which the nurse is responsible. Believing in the importance of nursing diagnosis, its teaching was introduced 4 years ago in the subjects of Woman s Health Assistance and Perinatal Nursing, in the 6o. period of the undergraduate course in nursing at UNICAMP. Aiming at evaluating these experience, we proposed to get the students opinion and obtain subsides to perfect teaching. Teoric teaching of 4 hours was given and it was indicated the basic bibliography. The supervised practical application was developed during 21 hours in a neonatal unit and 45 hours in health centers. At the end of the subjects, 16 students answered a form with closed and open questions. All the students considered valid the study of the nursing diagnoses. Most of the students considered more proper to introduce the teaching in the 3o. semester, when the nursing basic procedures is begun. As to the difficult of learning in the use of diagnoses, 68.7% of the students reported a difficult level higher to 25% and lower to 75%. The students group considers that the study of nursing diagnoses brought modifications in its concept of nursing assistance.3180-8
