Run by Columbia University's undergraduate science journal editorial team, CJSJ has roughly a 3% acceptance rate — among the most selective high school science journals in existence. Peer review is conducted by Columbia undergraduates under faculty supervision. Accepts original research and strong literature reviews in natural sciences, physical sciences, engineering, and social sciences. Research must have been conducted while the student was enrolled in high school.
Authorship: Solo or co-authored student submissions. A signed mentor or principal investigator (PI) permission-to-publish form is required — papers without it are desk-rejected. No faculty co-authorship of the paper is required.
Advice: Treat this as a reach. The Columbia affiliation makes it one of the most recognized high school science journals by college admissions readers.
Deadline: Fixed annual cycle. Submissions open July 6 and close September 30. Semifinalists notified November; finalists December; publication March of the following year.
