This study describes a psychometric evaluation of high school student responses to the Colorado Learning Attitudes about Science Survey (CLASS), and the subsequent development of a more parsimonious attitudes and beliefs survey structure for potential use with K-12 students in physics courses aligned with the Next Generation Science Standards. Pre- and post-survey response data were obtained from high school students in the 2017-2018 and 2018-2019 school years, whose instructors were partnered with the "Physics through Evidence: Empowerment through Reasoning" project. Exploratory factor analysis methods were used to propose a physics attitudes and beliefs survey with a more parsimonious factor structure, and confirmatory factor analysis methods provide support for the survey's structural stability. These preliminary results suggest that the CLASS is fertile ground for the development of shorter attitudes and beliefs surveys that may be more easily implemented and interpreted by instructors in K-12 contexts. Replication analyses and potential uses of the more parsimonious survey structure are also discussed.
