The aim of this study was to identify the level of physics teachers' practice for the secondary stage of the next generation of science standards, the study sample consisted of (64) secondary physics teachers in Taif city. To achieve the purpose of the study, the researcher used the descriptive approach, and a questionnaire was designed as a tool for applying the study. The results of the study found that the teachers lacked knowledge of the disciplinary core ideas of physics in the next generation science standards (NGSS), which represented the lack of their classroom practices of chemistry and information technology, which formed a fundamental part of the disciplinary core ideas of physics, teachers also implement most scientific and engineering practices, but do not implement all eight practices. The results of the study showed that there is not enough understanding of the engineering practices and how they are applied, and the results indicate the weakness of availability of crosscutting concepts in the practices of teachers in general, and the study recommended that the teachers of science be informed of the standards of the next generation science and that they should be applied in their classroom practices through professional development programs.
