Frequently Asked Questions

What are the editors’ experience/qualifications?

All our 100+ editing professionals are native English speakers and alumni of leading U.S. and U.K. universities.

 

As minimum criteria, all of our editors meet or exceed the following key standards:

 

  • Advanced qualifications (first degrees, master’s degrees, and PhDs) from a U.S. or U.K. university
  • At least five years’ experience in academic proofreading and editing or copy-editing
  • Significant track records in academic publishing or the commercial sector
  • Membership in leading industry bodies, such as the Society for Editors & Proofreaders (SfEP) and the Council of Science Editors

 

Additionally, editors are put through a rigorous assessment process. Less than 1% of editors who apply are accepted into our network.

Will you re-review changes that I make?

After we have returned your document, should you make some changes to it, we will be happy to review them for you. There will be no extra charge, assuming that the changes are not too extensive (e.g., a few sentences/paragraphs, as opposed to entire pages).

 

To review substantial changes – for example, the entire document or sizable sections of it – an additional charge will be applicable.

Can you work to a specific style guide/format?

We can edit documents to specific style guides/formats.

 

Among our 100+ editing professionals, we have format specialists across all the main style guides, including APA, Chicago, Harvard, OSCOLA, Oxford, and others.

 

If your university or publishing house has provided specific guidelines, we may be able to accommodate these. Please contact us if you have questions.

What are the key benefits of using your service?

Please see ‘Why Choose us?’ and ‘How We Improve a Text’ for an overview of the benefits of our service.

How will you improve my writing?

For a detailed explanation with an example, please see How We Proofread and Edit Texts.

 

We proofread for:

 

  • Grammar, punctuation, and typographical errors

We edit for:

 

  • Clarity
  • Incorrect sentence structure and awkward phrasing
  • Academic tone and style
  • Wordiness/repetition

 

All the editor’s changes are highlighted using the Track Changes feature in Microsoft Word, which allows you to see where improvements have been made. Click here to see working sample files of our work.

 

We can review your document in line with any specific guidelines (e.g., APA, MLA, Chicago, Harvard, Oxford, etc.) or requirements that you may have.

 

If you’re looking for a cheap, basic and rushed proofreading service, we suggest you stop reading now and look elsewhere – though we advise you to be vigilant of scam websites.

 

If, however, you are looking for a premium quality review and improvement of your writing at a good value price, we can help.

How do you choose which editor will proofread my document?

With over 100 editing professionals, we have experts across the full spectrum of academic disciplines. This broad base of expertise allows us to pair documents with editors who are familiar with their subjects/topics.

 

The editing manager opens each file and evaluates the content. From there, it is assigned to the editor on our team who has the most appropriate experience and qualifications relevant to the paper’s subject/topic.

 

Whilst we ensure that your editor has experience in your discipline, we cannot always guarantee that he/she will always be an expert in your sub-discipline. For example, if you submit a paper on molecular biology, we may pair it with an editor with a background in the wider discipline of biology but not necessarily in the specific sub-discipline of molecular biology.

 

We believe that there is no substitute for subject-matter expertise.
