1. To submit articles to our journal it is necessary to go to http://www.iesalc.unesco.org/ess/index.php/ess3/about/submissions y and follow the instructions for registration as an author of the journal. Once registered, you can submit articles online through our platform in a few steps and check their status.

2. The text of the articles must be anonymous. To this end, you must ensure that a version of your article is attached that does not contain the name of its authors or any information relating to them (institution to which they belong, own bibliographic citations, etc.). In addition, all citations, acknowledgements, references, and other allusions that may be direct or indirect to the identification of the author should be removed. All metadata related to the author/s should be completed within the journal's OJS platform in step 3 (Enter metadata) of the submission. In this step it is also mandatory to fill in the ORCID field. Authors who do not have an ORCID record should register at https://orcid.org/register .

3. Articles can be written in Spanish, English or Portuguese. They should have a minimum length of 3,000 words and a maximum of 8,000 words, including references, tables, figures, and texts of section 4. It is recommended to use Calibri font, 12-point size and single spacing. There should be no space between paragraphs.

4. Each paper should have a title (concise and informative of the content, with bold text format at 14 points, upper/lower case), an abstract (with a maximum of 250 words, in IMRYD format: Introduction, Method, Results, Discussion). At the end, three to five key words or descriptors (separated by semicolons) should be included. These three sections should be in Spanish, English, French and Portuguese. It is important to note that a maximum of 5 keywords should be provided. These keywords will be used for indexing purposes and should be chosen from the controlled list of keywords of the UNESCO Thesaurus (available at http://vocabularies.unesco.org/browser/thesaurus/en/groups ).

5. The manuscript should preferably be formatted according to the ESS Manuscript Template in Microsoft Word, available for download here. Three files should be submitted simultaneously: a) Manuscript, strictly following the above-mentioned template; b) Author data for cover page, according to the official template available here; and c) Statement of authorship and originality, downloadable from here. (Note: The review process for articles not formatted according to the ESS manuscript template may be considerably longer and protracted). The submission file is in OpenOffice, Microsoft Word document format and is submitted via the journal's website: http://www.iesalc.unesco.org/ess/index.php/ess3/about/submissions . No other means of submission will be accepted, nor will correspondence be entered into on originals, which are not submitted through the portal or in other formats.

6. Non-textual elements (tables, charts, maps, graphs, illustrations, diagrams, drawings, images, etc.) will appear in the appropriate place in the text. In addition, embedded graphs, charts, diagrams, and tables that cannot be edited from the text must be sent in files independent of their source program (JPG, TIF, XLS, etc.), since in many cases they are not valid for subsequent editing.

7. Citations and references. The APA 7th edition will be applied. Updated information on the citation form can be consulted in the APA (American Psychological Association) page. The following is an excerpt as a guideline:

- In-text citations. References to articles or books should appear in the text in parentheses, indicating the author's last name and year, separated by a comma (Navarro, 2018). If several books or articles are included in the same reference, they will be cited, below, in alphabetical order and separated by a semicolon (Navarro, 2018; Ramos, 2017). Articles by the same author are divided by commas, distinguished - if they are from the same year - by the letters (a, b, c, ...) (Ramos, 1990, 1995, 2000a, 2000b, 2000c, 2017). If the author's name is part of the text, the year of publication will be included: ... in a certain way Ramos (2017) predicted that education ...

- Textual citations. Textual quotations with a length of less than 40 words will be enclosed in quotation marks and then, in parentheses, will indicate the surname of the author of the text, the year and the page or pages from which the text was extracted. Example: "A methodology that favors a critical attitude in students generating [...] that are more functional and lasting" (Navarro, 2018, p. 51). If the author's name is part of the text, it would be like this: According to Nogueira (2018, p. 12) "...". Quotations of 40 or more words will appear in a separate text block, without quotation marks and set at the same height as the first line of a new paragraph. At the end, the author, year, and page/s should be indicated in parentheses.

- Bibliographic and electronic format references. The information will go at the end of the text in alphabetical order in a single list, all references provided have been those cited in the text and verified. Its format will be as follows:

8. Once a text that complies with all the formal requirements is received, it will be acknowledged, and the evaluation process will begin. If in the initial review (Relevance Review), the article does not meet all the requirements, the author will be asked to send the text again with the required changes. The deadline to send the article with the requested changes will be one month. If the deadline is not met, the article will be rejected and archived. In this first phase, the Editorial Team will carry out a global review of the quality, the thematic adequacy of the work and the adequacy of the article to the present rules of publication of the ESS, being able to reject directly, without going through external evaluation, those works whose quality is clearly low or that do not make any contribution to the thematic areas of the journal.

9. Articles that pass this first filter will be assigned to an editor, who will send them to two external evaluators, specialists in the subject or line of research in question. If the evaluations are discrepant or for any other reason, the editor may send the text to a third evaluator. See more about the Scientific and Academic Evaluation Policy of this journal.

10. Based on the evaluators' reports, the editor may make one of the following decisions, which will be communicated to the author:

  Publishable: Accept the submission as is or with slight modifications, without the need for further revisions.

  Publishable with modifications: In this case, publication will be conditional on the author making all the required changes. The deadline for modifications will be one month and a brief report explaining the changes introduced and how they meet the editor's requirements must be attached. If this deadline is exceeded, the article will be filed as "unpublishable".

  Re-evaluable: Refers to an article that at the time of review is not publishable, but with the possibility of rewriting and resubmitting the work. In this case, the resubmission of a new version will not imply any guarantee of publication, but the evaluation process will start again from the beginning. The deadline for sending a new version of the article will be three months and must include a brief report explaining the changes introduced and how they meet the editor's requirements. If this deadline is exceeded, the article will be archived as "unpublishable".

  Unpublishable: Rejected. Deficiencies identified in the manuscript, which are justified and reasoned with a qualitative and quantitative evaluation, indicate that the publication should be rejected.

11. Structure of the article: The submission must correspond to one of the Article Types identified in the Section Policy and be structured as specified therein. In general terms, it should include the following: The manuscript is divided into sections as befits a research article (e.g., Introduction, Main body of the text, Methods, Results, Discussion, and Conclusions). Subsections will be numbered as 1.1 (then 1.1.1, 1.1.2, etc.), 1.2, etc. Each subsection may carry a short title, and each title should appear on its own line. A brief description of this would be as follows:

An introductory part should specify the purpose of the article, identifying the problem, background in the research area or its gap, justification of the problem or question in a clear, coherent manner and based on the literature, showing unequivocally the relevance of this. In the section corresponding to the development, the theoretical and methodological basis should be distinguished; that is, how the problem has been studied, explaining it clearly and explicitly. A section devoted to the presentation of the results allows showing the contextualization of the results, both expected and unexpected, through texts, tables, graphs, and illustrations. The discussion is the space to expose what the results mean, through interpretation with its strengths or weaknesses, recommendations, and conclusions; and the latter can only be derived from the arguments handled in the body of the work and the references. They must be clear and express the final balance of the research or the application of knowledge, sometimes integrated in the Discussion. Finally, the references. The following should be considered in this regard:

References

In the manuscript, the sources and materials used should be correctly explained and cited. References should be prepared according to the latest or most recent edition of the Publication Manual of the American Psychological Association (APA). Each reference cited in the text in a manner relevant to the subject matter should also be present (properly referenced) in the reference list and vice versa, presented in alphabetical order. They should be as timely and current as possible, preferably citing works published in the last 5 years. We suggest no less than 10 references, varied (international) and current. Authors should not self-cite. A DOI (Digital Object Identifier) should be provided for all references cited in the manuscript that contain it (http://www.doi.org/ ). Whenever possible, URLs of references should also be provided.
