Dear Dr. Özdemir,

Thank you for submitting your manuscript to PLOS ONE. After careful consideration, we feel that it has merit but does not fully meet PLOS ONE’s publication criteria as it currently stands. Therefore, we invite you to submit a revised version of the manuscript that addresses the points raised during the review process.

Please submit your revised manuscript by Nov 03 2022 11:59PM. If you will need more time than this to complete your revisions, please reply to this message or contact the journal office at plosone@plos.org. When you're ready to submit your revision, log on to https://www.editorialmanager.com/pone/ and select the 'Submissions Needing Revision' folder to locate your manuscript file.

Please include the following items when submitting your revised manuscript:

• A rebuttal letter that responds to each point raised by the academic editor and reviewer(s). You should upload this letter as a separate file labeled 'Response to Reviewers'.
• A marked-up copy of your manuscript that highlights changes made to the original version. You should upload this as a separate file labeled 'Revised Manuscript with Track Changes'.
• An unmarked version of your revised paper without tracked changes. You should upload this as a separate file labeled 'Manuscript'.

If you would like to make changes to your financial disclosure, please include your updated statement in your cover letter. Guidelines for resubmitting your figure files are available below the reviewer comments at the end of this letter.

If applicable, we recommend that you deposit your laboratory protocols in protocols.io to enhance the reproducibility of your results. Protocols.io assigns your protocol its own identifier (DOI) so that it can be cited independently in the future. For instructions see: https://journals.plos.org/plosone/s/submission-guidelines#loc-laboratory-protocols. Additionally, PLOS ONE offers an option for publishing peer-reviewed Lab Protocol articles, which describe protocols hosted on protocols.io. Read more information on sharing protocols at https://plos.org/protocols?utm_medium=editorial-email&utm_source=authorletters&utm_campaign=protocols.

We look forward to receiving your revised manuscript.

Kind regards,

5. Review Comments to the Author

Please use the space provided to explain your answers to the questions above. You may also include additional comments for the author, including concerns about dual publication, research ethics, or publication ethics. (Please upload your review as an attachment if it exceeds 20,000 characters)

Reviewer #1: The paper is timely, well written and addresses an issue that needs to be dealt with as the world goes into its post COVID19 pandemic phase. The methodology and the results obtained are clear and consistent. In my view the discussion of the results is somewhat deficient. In many cases the questions of "Why" and "What does this mean" are lacking. Oftentimes the discussion mirrors the way in which the results are written. I noted also that in spite of the fact that the paper has 53 references, the discussion is void of references except for lines 299 and 302 where reference 2 is used. Discussion section therefore needs to enhanced through a comparison with previous studies. While this is the first time we have had education affected in this by a COVID pandemic, it is not the first time that children have been denied an education due to factors such as disease (West Africa Ebola outbreak of 2013–2016), wars (world war 2) and natural disasters (Nearly 40 million children a year have their education interrupted by natural disasters). Publications in these scenarios can be used to enhance the discussion.

Reviewer #2: The manuscript is technically sound and well prepared. There is novelty in the topic and well supported with the literature review. Results are well presented though complex to understand. In the data and methods there is mention of three major scenarios for which the explanation is given. whereas in the results, there is a sentence "according to four scenarios" (line 268) which is not clear to the reader.

Reviewer #3: Well presented analysis on impact of school closure during COVID 19 on adult skills in due to impact of school closure,

The paper doesn't talk about any impact on how it may affect health or its correlation.
