Plain Language Standard

Why the WriteMark matters more than ever in the age of AI writing

One of our favourite plain language mottos adorns the wall in massive text at Write’s Wellington office. It’s from Sir Ernest Gowers’ book, Plain Words: ‘Be short, be simple, be human’.

It’s a motto that follows its own advice.

In the burgeoning age of ‘AI’ text generation, human writing for human readers is more important than ever. And that makes the WriteMark an even more valuable symbol of people-centric plainness.

Here’s why a quality mark for clear communication matters even more in the age of AI.

People-centric writing stands out in an AI-generated torrent

The WriteMark has always been a way to show your readers you care.

The heart-shaped symbol demonstrates your commitment to being clear, open, and customer-focused. It signals to your audience that you’ve gone the extra mile to ensure they understand what you’re telling them, which builds trust and confidence.

We think readers will particularly appreciate the WriteMark’s quality promise as AI writing proliferates. AI-generated text risks ‘infecting’ AI training data — the library of information that AI tools use to create their responses. This may degrade the quality of AI outputs over time, as they reinforce and amplify their own distortions and biases. Commentators have called this an ‘AI ouroboros’

In this uncertain future of AI writing, the WriteMark will signify people-centric writing that gives readers confidence and helps to form human connections between author and audience.

Our human assessors give human insights

In a WriteMark assessment, qualified experts read documents, assess them against 25 carefully selected criteria, and produce a report packed with insights and recommendations. They apply a critical eye, drawing on their experience and understanding — as both writers and readers — to identify what works and what needs work. This experience and insight helps to shape documents that serve their writers — and their readers.

AI can do some incredible things, if you know how best to use it. By drawing from untold libraries of human writing and thought, it can generate convincing text and images in the blink of an eye. It can educate and entertain, adapting its tone and language for any conceivable audience. But AI is not critical, creative, or insightful — not yet.

Big-picture elements require critical thought

AI can provide lots of helpful advice for some of the more mechanical aspects of plain language, like sentence structure and word choice. But humans can still do a few things better — like thinking.

‘Artificial intelligence’ is a bit of a misnomer, because tools like ChatGPT and DALL·E 3 are not thinking or creating. They draw on vast sets of training data from the web and use predictive patterns to spit out realistic answers to prompts.

This means AI would struggle to meet or assess some WriteMark criteria, especially big-picture elements. It takes critical thought to determine whether a document has:

  • a clear purpose
  • an overall structure that helps readers to understand it
  • answers to all the questions a reader is likely to ask.

AI is improving constantly, and quickly. But answering these questions requires critical analysis and holding the ‘big picture’ in mind — skills that today’s AI tools can only imitate.

AI can be a cultural liability

Our assessors have another advantage over AI tools — their Kiwi cultural context and sensitivity.

AI tools draw on training data from all corners of the internet. This means they tend to replicate and reinforce existing biases in that data. Aotearoa New Zealand represents a tiny corner of the internet, so our cultural differences are easily overwhelmed by American and European norms in AI’s predictive patterns.

Why does this matter? One element we assess for the WriteMark is whether the document has an appropriate style and tone for its audience. Aotearoa’s cultural context is different from the rest of the world in lots of small ways — as well as the big ones, like the role of te reo and te ao Māori. The words we use and the way we express ourselves are distinct, as are our history, economy, politics, and culture.

AI tools are liable to get these small things wrong, because they draw from the wilderness of the World Wide Web. As well as setting the wrong ‘style and tone’ for our specific cultural context, relying on AI can lead to embarrassing and even offensive errors.

The WriteMark Plus gives unrivalled insight into how readers experience a document

On top of using human experts to assess documents for the WriteMark, we get human non-experts to test how well a document serves its readers for the WriteMark Plus.

User-testing with real readers always uncovers unforeseen sticking points. Human testers can help identify things like:

  • whether a certain word choice or section is confusing
  • whether a document’s structure matches readers’ expectations
  • whether a document is accessible to readers of all abilities
  • whether a document is practical to use in the real world.

AI is clever, and convincing. But there’s simply no substitute for testing a document with its target audience.

AI can be a powerful plain language tool — learn how to use it safely

While human expertise can’t be beaten when it comes to the high standard of the WriteMark, we still recognise the value of this powerful tool.

That’s why Write has added an AI Writing Insights workshop to our roster, and why we’re keeping up to date with advances in the field.

How does the WriteMark compare to a new international standard?

We’ve mapped out how the WriteMark sits next to the new ISO Standard. We wanted to be sure our mark of plain language quality aligns with international best practice. And we wanted to understand where and why the two standards differ | Photo by Alexander Suhorucov on www.pexels.com

In June 2023, the International Organization for Standardization, or ISO, released Part 1 of its first-ever Plain Language Standard. The ISO Standard offers guidelines for writing in plain language, arranged around four organising principles. These establish that information should be relevant, findable, understandable, and usable.

Read our blog about the ISO Standard over on the Write website

How does the WriteMark® Plain Language Standard, developed here in Aotearoa New Zealand, compare to the new international standard? Do the two standards have any disagreements?

If your document holds the WriteMark, does it also meet the criteria in the ISO Standard?

Is the WriteMark keeping pace with international best practice?

Let’s answer those questions one by one.

Comparing the WriteMark to the ISO Standard

As we pointed out in our blog post on the Write website, the ISO Standard doesn’t include quantitative measures. It doesn’t give users a way to certify documents that ‘meet the standard’.

So, right off the bat, the ISO Standard does something quite different from the WriteMark.

The WriteMark logo shows that we have assessed a document and we recognise its excellence in clarity and presentation. The WriteMark uses 25 criteria to evaluate whether or not a document or website meets a high standard of plain language.

But although they have different purposes, the guidelines in the ISO Standard broadly align to the criteria in the WriteMark.

Here’s an example.

  • Guideline 5.2.4(a) in the ISO Standard says to ‘Use a new heading when introducing a new topic’.
  • To achieve the WriteMark, a document must have ‘useful, informative headings to guide the reader’.

The ISO guideline is more specific, but the WriteMark requirement captures the same intent.

Many of the ISO Standard guidelines go into more detail than the WriteMark criteria. The WriteMark simply asks if a document’s structure is ‘clear and logical to the reader’. The ISO Standard, in comparison, recommends:

  • placing the most important information first
  • separating supplementary information
  • presenting instructions in chronological order
  • and several more specific guidelines.

These guidelines are all part of a ‘clear and logical’ structure. The guidance in the ISO Standard and requirements of the WriteMark aren’t at odds — they’re doing different things, at different levels of detail.

The ISO Standard emphasises a different purpose

The ISO Standard and the WriteMark do, however, place emphasis in different areas. These differences are worth exploring.

The first area is the document’s ‘purpose’. For the WriteMark, a document needs to have a clear purpose, and its content needs to support that purpose.

Makes sense, right? We know that documents are most effective when they’re written with a clear goal in mind.

The ISO Standard, however, strongly emphasises the purpose of the reader. Writers should identify their reader’s purpose for reading their document, and put their readers’ needs first.

This also makes a lot of sense! Clear plain language documents put their readers first.

So which perspective is correct? Successful documents will fulfil both their readers’ and writers’ purposes. They’ll achieve what their author needs them to, while being entirely transparent and practical for readers to use.

The question is whose purpose is front of mind, and when. And that will depend on your document, your audience, and, of course, your own purpose for writing.

We explore this question further in another blog on the Write website:

Comparing the ISO Standard to the Plain Language Act and Write Plain Language Standard

The ISO Standard brings elements together under an umbrella of ‘cohesive’ writing

Another distinction between the ISO Standard and the WriteMark is in the idea that documents are ‘cohesive’.

The third principle of the ISO Standard, ‘understandable’, covers what we often think of as ‘language elements’. This means using familiar words, short and active sentences, concise paragraphs, and a reader-friendly tone.

The ISO Standard then collects these elements, along with the structure and headings from the principle of ‘findable’, under an overall direction to ‘Ensure that the document is cohesive’.

This means, in short, make sure all the parts of the document work together. They have clear and consistent relationships. They all serve a common purpose.

Unlike the ISO Standard, the WriteMark doesn’t have any one particular requirement for documents to be cohesive.

We’re already looking at how the elements of a document cohere throughout the WriteMark process. In a WriteMark assessment, we are checking that the words have a cohesive tone, that the structure presents a cohesive whole, and that the presentation elements are consistent and appropriate.

The guidance to write cohesive documents is handy, but as a requirement in the WriteMark it would only duplicate other elements we’re already assessing.

Does a WriteMark document meet the ISO Standard?

A document can’t ‘meet the ISO Standard’, because the ISO Standard is a set of guidelines, not requirements. But let’s put that technicality aside and rephrase the question in a way that we can answer:

Does a WriteMark document have the same quality of plain language as a document developed using the ISO Standard guidance?

To that we can confidently say, ‘yes’. Documents that achieve the WriteMark will also satisfy the ISO Standard’s organising principles. WriteMark documents are all different, but each one is:

  • purposeful and reader-focused to ensure information is relevant
  • organised and structured to make information easy to find
  • welcoming and clearly written to make information easy to understand
  • practical and concise to make information easy to use.

And this relationship goes both ways. If you follow the guidelines in the ISO Standard, you’ll develop a document that’s well on its way to meeting the WriteMark.

Again, we can find some differences in the details, but the two standards are well aligned overall.

For example, to achieve the WriteMark, a document must use mostly positive sentences. The ISO Standard doesn’t mention positive or negative sentences — possibly because it applies across languages, not just English. But its instructions to write concise sentences with a clear structure will ensure they are also mostly positive.

Updating the WriteMark to keep pace with international best practice

We want to be certain that the WriteMark reflects the best practice in plain language, which means updating it from time to time. The ISO Standard finally arriving after years in the making has been a good prompt for us to make some tweaks.

Following the emphasis in the ISO Standard, we’ve added a cue to the WriteMark assessment to note a document’s purpose and audience. This gets us and our clients thinking about the ISO Standard principle of ‘relevant’.

It’s a reminder to consider:

  • who you’re writing for
  • your readers’ context when encountering your document
  • what you and your readers hope to achieve with this document.

We’ve also added a reminder to the assessment about making documents cohesive. This notes that a document is cohesive if its language, presentation, and big picture elements all support its purpose and the purposes of its readers.

And we took this opportunity to align the wording in some of the WriteMark criteria more closely with Write’s Plain Language Standard, just to keep things tidy.

Start as you mean to go on — with clarity

Verity White of Checklist Legal believes plain language builds trust in client relationships | Photo courtesy of Checklist Legal

For a small-to-medium business, working with people who have similar values and goals is really important. Building a lasting and valuable client relationship relies on trust, and from the client’s perspective, that relationship starts at the point of engagement. So Verity White of Checklist Legal decided she wanted really clear documents to start off the client relationship.

She drafted the documents herself but decided to get some external help from Write and WriteMark. That way she could be doubly sure the client would know what they were signing up to and the relationship would start off on the right foot.

Checklist Legal makes legal advice clear

Verity’s company is all about taking the stress and confusion away from legal situations. One of the main ways she achieves that is through her clear, easy-to-understand advice. She creates readable documents that help her clients achieve their business goals.

Contracts are a core part of a business and reflect the way a business builds a client relationship. Verity is passionate about the ways that clear contracts support client connection and engagement, representing an authentic brand voice, so that the contracts feel like something that belongs to the business. That’s why achieving the WriteMark felt so important to Verity and Checklist Legal.

Verity tells her story below.

Using the ‘Rewrite’ principles to achieve clarity and develop trust

I first came across Write when I attended the plain language conference in Wellington, New Zealand in 2016. I absolutely fell in love with Write as a plain language organisation and with their Rewrite for Change programme. I knew I wanted to be involved with them in some way, shape, or form! And it took launching my own boutique law firm to make that opportunity come about.

Start as you mean to go on — with clarity WriteMark

I thought my engagement documents were pretty good. I had met a bunch of the readability criteria that I had set for myself in creating them, as well worked on the information design. And then I got some really helpful feedback from the Write team, and they helped me refine things a little bit further.

Getting an independent peer review

Camilla Anderson, one of my other plain language and visual contracting heroes. always says that if you had two people speaking French and you wanted to simplify French into a different language, you wouldn’t get French people who only speak French to simplify that language.

So when it comes to simplifying legal writing, having someone else take a look at your own legal writing is often a great approach. It gives you a fresh eye, and it is that trained professional view that I really appreciated from having Write go through the documents. Of course, the ultimate decision on the legal bits and pieces of the documents sits with me. But I really appreciated the advice and patience of the Write team, as we worked through the finer points of the wording together.

Walking the talk by achieving the WriteMark and other certification

I wanted to be able to show that I was walking the walk and talking the talk when it comes to plain language, which I think is really important for law firms. A lot of law firms claim to be writing in plain language, but they really don’t go to the effort of getting their documents checked out fully. And I think that’s shown by the fact that Checklist Legal is the first law firm in Australia to have certified its plain language engagement documents with Write.

In very exciting news, Checklist Legal has recently become a certified B Corp! And I’ve published my new book called Create Contracts Clients Love — the title says it all really!

Reaching a plain language standard helps you reach your audience

Aim high — achieving a plain language standard will help your document work for your readers


An international colleague asked us about our two plain language standards:

Is the Write Plain Language Standard the same as the criteria for assessing a document and giving it the WriteMark? Or are the Standard and the WriteMark two different and separate tools?

Here’s how the two Standards came to be, how they relate to each other, and how they’re different.

The Write Plain Language Standard is available for all to use

The 10 elements in the Write Plain Language Standard are a highly condensed version of the 28 elements in the WriteMark Plain Language Standard.

The WriteMark came first, and only documents assessed by our approved assessors can carry it. Several years later, because our clients wanted a standard they could apply themselves, we created a shortened form.

This shorter, easy-to-use standard became Write’s Short Plain English Standard. We’d customise it specially to suit our clients’ specific needs. And clients would often include their standard in their style guide.

Eventually we made the short form (now called the Write Plain Language Standard) freely available under a Creative Commons licence. Anyone can use it to check and improve the quality of their writing.

We often use the Write Plain Language Standard as an audit tool. Our clients want to understand how their writing measures up against widely accepted plain language criteria.

The WriteMark is a mark of document quality available by assessment

We use the WriteMark criteria when an organisation wants to show that their document has been independently assessed as meeting a very high standard of plain language. Achieving the WriteMark gives them the right to display the WriteMark logo — seen as a quality mark — on their document.

WriteMark Plus is another option we’ve recently developed. It combines the WriteMark’s elements-based assessment with document user-testing. We or another approved testing agency will test the document with readers who match the profile of the target reader.

Many clients now prefer to achieve the WriteMark Plus, which demonstrates an even greater commitment to plain language.

We all hope we’ll always be able to make our own decisions about our healthcare. But what if we can’t?

The Kimble Center for Legal Drafting, based at Western Michigan University–Cooley Law School in the US, has published a new Power of Attorney document. People can use the Power of Attorney to set up someone they trust to make decisions about their healthcare if they’re not able to. What’s more, the Power of Attorney is easy to understand — and it’s free to use for US citizens.

The Kimble Center’s legal team decided they wanted their new document to be top of its class. So they first asked the members of their advisory board for feedback. Then they applied for another layer of review through the WriteMark assessment process.

The WriteMark assessment considers purpose, structure, content, language, and design as part of a rigorous document analysis.

Design to support the purpose of the document

The Center engaged the team at Gusto Design to create a design that would support clarity and readability.
Annette Ellis, Creative Director at Gusto, explains:

We worked with the Kimble Center for Legal Drafting to make a complex process clear and easy to understand. The plain language used for the Power of Attorney form is visually supported using design elements that guide the user through the form, making it easy for them to understand and fill out.

Instructions are provided as shaded boxes adjacent to the form fields, providing users with additional information that helps them understand how to fill out the form correctly. This extra guidance is critical to ensure the form accurately captures their wishes.

All boxes ticked

With its plain language and simple design, the Power of Attorney for My Health Care goes to the top of its class. It meets all the elements of the WriteMark Plain Language Standard — and it’s the first document of its type to achieve the Standard.

Joseph Kimble, Distinguished Professor Emeritus at WMU–Cooley Law School, acknowledges the input from the WriteMark team:

I’m grateful for the invaluable suggestions we received from Anne-Marie Chisnall (a member of our international board of advisers) and then from the WriteMark assessment team. Those suggestions significantly improved almost every page.

And tested with users too

Since we originally published this story, researchers at Michigan State University have user-tested the Power of Attorney document. The Kimble Center applied recommendations from the user-testing report and did a little rewording and redesigning of the document. With these changes, the Power of Attorney achieved WriteMark Plus.

WriteMark Plus is awarded to documents that have reached the WriteMark Standard and that also undergo user-testing for further fine-tuning.
