This article describes part of a research project conducted in secondary education settings whose objective was to design an assessment in the area of values development as regards mathematical problem solving. The assessment was administered to 285 second grade students at 23 city schools with a scientific-humanist focus in Chile's Los Rios and Los Lagos regions. The methodology used for the research was qualitative and quantitative; it included interviews and the administration of a test on math problems associated with values. The results showed a lack of integration of values with the teaching of mathematics, as well as the students' limited problem-solving ability.
