• IJSTS seeks to innovative scholarly manuscripts or posters on sciences, such as Biology, Chemistry, Physics, Medicine, and other relevant subjects).
• We also accept environmental and energy research papers and posters.
• For students' competition, the students must be in 9th to 12th grade or college students and be currently enrolled in a public school, a private school, or homeschooled.

The Multidisciplinary category serves as a dynamic collaborative hub for pioneering research that successfully transcends traditional academic boundaries to solve real-world challenges. We recognize that today's most complex global problems require the deep integration of insights from diverse fields—combining expertise from the sciences, humanities, social sciences, and emerging technologies.

• A paper that emphasizes any area of the humanities, social studies, philosophy, business, or economy can be submitted.
• Social science phenomenon and humanities research as a major cause or effect would be accepted as well.
• Additionally, IJSTS welcomes featured articles that contribute to broadly defined improvement of general intellectual knowledge or empirical studies of abstract theories.

• The projects can contain any relevant engineering fields, including mathematical or computational science knowledge.
• Topics relevant to engineering such as mechanical, chemical, electrical engineering or material science would be suitable.
• For the students' comperition, the students must be in 9th to 12th grade or college students and be currently taking relevant courses in school.

The Health & Clinical Medicine category is dedicated to advancing global healthcare through the publication of pioneering medical research, clinical trials, and healthcare innovations. This section spans a wide array of vital medical disciplines, including internal medicine, translational oncology, pharmacology, immunology, and public health initiatives.

The Physical Sciences category encompasses the study of non-living systems, exploring the fundamental laws governing matter, energy, space, and time. This section features high-quality, peer-reviewed research, experimental studies, and theoretical reviews across key disciplines including Physics, Chemistry, Earth and Planetary Sciences, Space Science, and Materials Science.
