JELTAN operates double-blind peer review: authors do not know who reviewed their paper, and reviewers are not told who wrote it.

Every submission is first checked by the editorial office for completeness, anonymity and adherence to the author guidelines. Papers that pass are considered by an editor for scope, then sent to at least 2 independent reviewers, who are asked to report within 28 days. Reviewers recommend acceptance, minor revisions, major revisions, or rejection, and the handling editor takes the decision.

Authors receive the reviewers' comments with the decision letter. Papers returned for revision are resubmitted with a point-by-point response and may go back to the same reviewers.

Submitting to JELTAN means the work is original, has not been published before, and is not under consideration by another journal. All sources must be cited, and text taken from other work must be quoted and attributed.

Everyone listed as an author must have contributed to the work and approved the submission; anyone who contributed but does not meet that bar should be acknowledged instead. Competing interests and funding must be declared. Research involving people requires ethical approval and informed consent.

Where an error is found after publication we will issue a correction; where the findings are invalidated, the article will be retracted and the notice will say why.

Articles in JELTAN are free to read and download. Authors retain copyright in their work.

A charge of NGN 30000.00 becomes payable once a paper has been accepted. There is no charge to submit, and the charge has no bearing on the editorial decision — it is raised only after acceptance.

Authors who cannot meet the charge should write to the editorial office; waivers are considered case by case.
