This editorial reviews its history, current standing, and strategy for international indexing. CHNR adopted its present title in 2013, moved to English-only publication in 2020, and is indexed in CINAHL, Scopus, DOAJ, and PubMed Central. Its Scopus CiteScore rose every year, from 0.9 in 2021 to 2.5 in 2025, and SCImago placed it in the second quartile in both of its subject categories in 2025. Volume 32 (2026) comprises 42 articles, up from 28 in 2025; 24% involved authors from outside Korea. Building on these gains, CHNR aims for inclusion in the Web of Science Core Collection and, ultimately, MEDLINE. Four strategies will guide this effort: broadening author diversity, strengthening the international editorial board, publishing work that is read and cited, and upholding publication ethics. The 2026 revision of the Instructions for Authors supports these goals. Editors, reviewers, and authors share responsibility for the journal's next leap.</p>","PeriodicalId":37360,"journal":{"name":"Child Health Nursing Research","volume":"32 4","pages":"355-359"},"PeriodicalIF":0.0,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149300850","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
