What an OET correction report should contain

Price and speed are easy to compare. The report is what you actually study from, so it is worth knowing what each one gives you. Below is what our report contains, beside what one other provider's published sample shows. A sample cannot show how accurately a letter was marked, only what the report includes.

An OET Writing Correction report: estimated grade, two priorities to work on and a mark for each of the six criteria

Corrections under each paragraph of a letter, each with the mistake crossed out, the fix, the reason and the criterion

In the report	OET Writing Correction sample	Benchmark's published doctor sample
Overall estimate and grade	Yes, with what the grade means	Yes (C+, 320 out of 500)
A mark for each of the six criteria	Yes, in OET's own wording	Comments in a paragraph, no mark per criterion
How corrections are shown	Paragraph by paragraph in a separate report, each tagged by criterion with the reason	Margin comments inside your own Word document, which many students find easy to follow
Your letter, corrected	Yes, your content in your order	Not in the sample
What to do next	Study plan: grammar, words, phrases and practice sentences	A list of 10 general advice points

Benchmark's sample is its own published doctor sample, dated 2021, read on 22 October 2026; its current reports may differ. We have not reviewed other providers' sample reports. If anything here is out of date or unfair, tell us and we will correct it within a day.

Each service in detail

OET Writing Correction

OET Writing Correction marks each letter by hand against all six OET writing criteria, and returns a line-by-line annotated PDF in as little as 24 hours. Corrections are led by Dr Mariam, a PhD English Professor with 20+ years of OET experience, and cover 12 healthcare professions. Best for candidates targeting Grade B (350+) who want feedback on their own practice letters.

Benchmark Education

Benchmark Education sells per-letter packs, from a single letter to bulk packs of 20, 30 and 50, with regular and urgent speeds. Its page says letters are read by a team of doctors, nurses, pharmacists and ESL tutors. Packages are valid for one year and are non-refundable.

Swoosh English

Swoosh English sells packs of 5, 10 and 15 letters marked by experienced OET teachers, with feedback within 24 hours seven days a week. The larger pack adds video courses, class recordings and mock exams. Refund requests are accepted within 7 days of purchase, subject to eligibility and a $30 admin fee.

OET with Dr Hesham

OET with Dr Hesham sells writing assessments as add-ons to an active course, with voice-note feedback on WhatsApp. The 7 and 10 letter add-ons name Dr Ahmed as the marker. Once a correction has been delivered it is generally non-refundable.

Accordemy

Accordemy sells writing mock tests in bundles of 5, 10 and 20, with optional teaching videos or a full online course. It is not a per-letter correction service, and its pages do not state how quickly practice tests are marked. Its pass guarantee covers the all-skills packages only.

E2 Language

E2 Language has no stand-alone correction product: writing feedback comes inside its OET Doctors and Nurses course packages, which run from 90 to 365 days. Its page says feedback is returned within 48 hours and the higher packages carry a score guarantee.

How to choose

Decide what you actually need. If you are still learning the letter genre, a course platform with a curriculum (E2, Swoosh) gives you structure. If you already know the format and need someone to mark your own letters against the criteria, a focused correction service is the faster route to Grade B.

Whichever you pick, confirm the provider marks against the six current OET writing criteria, and check the turnaround fits your exam date. Start by checking a draft free at Free OET Writing Check, then send your strongest letters for expert educator correction.

Frequently asked questions

What is the best OET writing correction service?

There is no single best service for everyone. For candidates targeting Grade B who want per-criterion feedback on their own letters with fast turnaround, OET Writing Correction is a strong fit. For a full course platform, E2 Language or Swoosh English suit better, and Benchmark sells low-priced per-letter packs. Match the service to whether you need focused correction or a broader curriculum.

Is there a free way to check my OET letter first?

Yes. Free OET Writing Check (freeoetwritingcheck.com), from the OET Writing Correction team, grades your letter against the six official OET criteria and flags the first error an examiner would catch, in about a minute. Use it to triage your draft, then send your shortlisted letters to an expert educator correction service before the exam.

Which OET correction service is fastest?

OET Writing Correction offers 24-hour, 48-hour and 72-hour turnaround on every letter pack. Swoosh English also states 24 hours, Benchmark offers 24 hours or 3 days, and Dr Hesham quotes 48 to 72 hours. Speed matters most in the four to eight weeks before your exam, when each correction needs to feed your next practice letter.

Do these services follow the 2026 OET writing criteria?

OET Writing Correction marks against the six current OET writing criteria (Purpose, Content, Conciseness and Clarity, Genre and Style, Organisation and Layout, and Language). The pre-2018 criteria are obsolete. Always confirm the marking standard with any provider before paying.

Is this comparison independent?

No. This page is written by the OET Writing Correction team, so it is not strictly independent. We have represented each provider fairly from publicly available information on their sites and candidate reviews. If anything is inaccurate, email [email protected] and we will correct it.
