Nusantara Journal of Education and Educational Research (NJEE) is committed to maintaining the highest standards of publication ethics and adheres to international best practices as outlined by the Committee on Publication Ethics (COPE), ensuring integrity, transparency, and accountability in all aspects of educational research publishing. Authors must guarantee that their educational research submissions are original, have not been published elsewhere, and are not under consideration by other journals, while properly acknowledging all sources, participants, collaborators, and funding agencies, and declaring any potential conflicts of interest that may influence their research design, data collection, analysis, or interpretation of educational findings. All educational research involving human participants, including students, teachers, parents, and educational institutions, must comply with relevant ethical guidelines and institutional review board approvals, with clear documentation of informed consent procedures, participant confidentiality protection, data anonymization protocols, and special considerations for research involving minors or vulnerable populations in educational settings. The journal maintains a rigorous double-blind peer review process where educational experts and practitioners provide objective, constructive, and confidential evaluations while declaring any conflicts of interest and declining to review manuscripts where personal, institutional, or professional relationships with authors may compromise impartial assessment. Editors ensure fair and culturally sensitive evaluation of all submissions regardless of author nationality, institutional affiliation, gender, cultural background, or educational context, maintaining strict confidentiality throughout the review process and making decisions based solely on educational significance, methodological rigor, ethical soundness, and contribution to educational knowledge and practice. NJEE has zero tolerance for research misconduct including plagiarism, data fabrication, falsification of educational outcomes, duplicate publication, ghost authorship, and inappropriate representation of participant voices or cultural contexts, employing comprehensive plagiarism detection systems and thorough editorial screening to identify potential violations, with established procedures for investigating allegations of misconduct and implementing appropriate sanctions including manuscript rejection, institutional notification, and publication of corrections or retractions when necessary. The journal promotes transparency and cultural responsiveness through open access publishing, inclusive authorship guidelines that recognize diverse forms of educational expertise, comprehensive conflict of interest disclosure, respectful representation of research participants and communities, and post-publication dialogue mechanisms, while encouraging authors to share educational data and materials in accordance with privacy regulations, institutional policies, and community consent, thereby fostering reproducibility, collaborative educational research, and ethical advancement of educational knowledge that serves learners and communities across the diverse cultural landscape of Nusantara and beyond.
