Most middle and high school students struggle with reading and writing in science. This may be because science teachers are reluctant to teach literacy in science class. New standards now require a shift in the way science teachers develop students' literacy in science. This survey study examined the extent to which science teachers report implementing science literacy practices from the Common Core Literacy in Science and Technical Subjects and the Next Generation Science Standards with their students. A survey detailing these practices was emailed to all secondary science teachers (N = 2519) in one northeastern state and 14% of them (n = 343) responded. Practices that aligned more closely with disciplinary literacy skills and strategies were implemented more often when compared to the practices aligned with intermediate literacy skills and strategies. Since the development and intermediate skills are important to support students' literacy progression from foundational to disciplinary, secondary science teachers may not be providing enough support for their students to be competently literate in science, in a fundamental literacy sense. This, in turn, impacts students' ability to use fundamental literacy skills toward knowledge-building in science, achieving a derived sense of science literacy.
