This study aims to explore the recently revised trend of technology-engineering literacy for students and children in the United States and the composition of benchmark contents by school level. The study can be used as basic data for revision of the technology education curriculum in Korea. In order to achieve the purpose of this study, literature research was mainly conducted. STL (Standards for Technological Literacy) and STEL (Standards for Technological and Engineering Literacy) published in 2000 and 2020 respectively were further intensively explored. The conclusions based on the results of the study are as follows. First, STL emphasized technological literacy. However, STEL was developed by focusing on technology and engineering literacy. Second, STEL was developed with close relation to STEM education in American schools, and is meant to promote it. Third, in consideration of the student s learning burden, the standard of STEL and the benchmark have significantly decreased from 20 to 8 and 279 to 142 respectively. Fourth, STEL increased the influence of standards by expanding the target students for learning to PreK-12. Finally, eight practices of technology and engineering were presented between context and standards to enhance the ability of the students.
