Resumen:
The School Mathematics Knowledge Test is an assessment instrument developed by a team led by the Centre for Advanced Research in Education (CIAE) at the Universidad de Chile, within the framework of the project "Diagnosis of Initial Beliefs and Knowledge about School Mathematics, its Learning and Teaching among Students of Primary Teacher Education" (FONIDE FX11624). The results of this research were reported in Martínez et al. (2019), with a description of the levels of mathematical knowledge of the students who participated in the study, their belief systems, and the relationship between both constructs.
