The objective of this paper is present an instrument to assess the conceptions of kindergarten teachers, on models of teaching Natural Sciences. A questionnaire was elaborated, which was submitted to a process of content validity, that is to say, to evaluate how adequate is the sampling that makes a test of the universe of possible answers from the perspective of Psychometry. The validation process began with the definition of the constructs to be analyzed and the opinion of experts. The agreement of pairs was established by means of concordance calculation, for which the intraclass correlation coefficient (CCI) was used, presenting agreement for fifteen of the thirty-two proposed items. Subsequently, the questionnaire was refined according to the returns received. The changes that took place mainly referred to the clarity and to whom the test is directed. To continue with the validity, interviews were conducted with the target population to analyze the adequacy of the instrument, from which a second modification was made, resulting in the questionnaire to be applied in the pilot sample. The process carried out so far highlights the importance of the process of validating instruments in didactic research, as well as in the effects of their non-observance, since the constructs and variables that are intended to be studied must be reflected in the tools that are constructed. In addition, the usefulness of the validated instruments lies in their replicability and in the possibility that they are available in an adequate way for future research.
