Sorry, catching up on a major email backlog!

I could go with 3 in principle, but only if we heavily amend what we request. I’m not sure that simple reading level is the answer – we can cite several examples where it is probably not. The problem is that our current text includes so many things that are, in my opinion, completely untestable (except with extensive and very well designed user testing).

For example, in #30<https://github.com/w3c/wcag21/issues/30> we have “unless it will result in a loss of meaning or clarity”, “unless they are the common form to refer to concepts for beginners”, “When a passive voice or a tense (other than present tense) is clearer.” and several more.

We could only begin to expect WCAG approval of some of our mega-SCs (like #30) if they are dramatically cut back to include a very few elements that are testable. This clearly means that meeting the SC will completely eliminate a large problem for everyone with a cognitive or learning disability, but it should ensure that they would have less problems. Almost all of the existing WCAG SCs are like this. There are no single SCs that, if met, will eliminate all the reading issues for blind users (for example). Even the full set of SCs will not do that.

The task we have of trying to improve things for people with cognitive and learning disabilities is infinitely more difficult than trying to address the needs of blind users (in my opinion). I think that all that we can realistically expect is to make some improvements in 2.1. If we are too ambitious then we will fail to do that.

An example of what I mean is #24<https://github.com/w3c/wcag21/issues/24>. The original tried to give detail as much as possible about how to reduce the cognitive load associated with dealing with “important information” in either textual or other media form. I think that there is no way that this vastly ambitious SC proposal could be edited to make it acceptable to the WCAG WG. I have made a proposal, which the SC Manager John Rochford seems to like, to only relate to “statements which instruct a user to make a choice or take an action”. Whereas we could, as Jeanne proposes, specify the appropriate reading level for such statements, I suggested just three bullets which I think are quite testable:

  *   have only one instruction per sentence, except when two things have to be done simultaneously;
  *   use sentences of no more than 15 words;
  *   should have no more than one relative pronoun per sentence. [with a glossary entry that lists all the relative pronouns]

I have sources to say that all three of these are known to be effective (but I have so far failed to find the time to specify them, which I should). Arguably sticking to these might be more effective than just specifying a reading level for these vitally important statements. I doubt that there is a great body of research that links the effectiveness of instructions (as such) with reading level. However, if we had to go with reading level I still think that it would make a positive contribution to improving the possibility that many users with cognitive and learning disabilities would find that they could understand instructions much better.

Best regards

I am changing my vote to 3 as well.
The SC as it  is incredibly easy to write testing tools for. there are a few open source  language processing tools that you can use to count cluses actureltys. Testing against a word list is also something that exists already in restricted language tools and is very easy to program. It cant be that we need to have a worse SC and use archaic reading level tools because WCAG are to set in their ways to accept any new technology.
All the best

We had issues with reading level , for example the word "mode" is a lower reading level than "hot or cold" . the lower reading level is much harder to understand.
The reason to go with Jeanne's proposal is because wcag _might_ find it more testable. This would only be, in my opinion, because they have not bothered read the whole proposal and testability section  (or they do not want new tools) Also i am not sure it is more testable in different languages and that is essential for WCAG. Wordlists requiremnts however, can work easily in any language and wordlists can be automatically generated by parsing a few sites.

I agree that the "unless..."  clause is only human testable but that it very typical for wcag.

I want to suggest three options

1 -  we retract our current pull requests and put these in instead

2 - we go with the current pull requests. If they fail and the comments are hard to address then we go with Jeanne's

3 -we go with the current pull requests. we can revisit this if needed

My vote is 3, to go with the current wording and see what happens

All the best

A group of us at The Paciello Group (TPG) have been meeting every week in January to comment on the WCAG 2.1 proposals.  Because we test WCAG 2.0 all day, every (business) day, we have a lot of experience with both the language of WCAG and the testing of WCAG.  What we decided this week is that we want to focus our efforts toward helping COGA TF draft success criteria that will get into WCAG 2.1 and will accomplish most of what you want -- even if it is phrased differently.

We started with the proposals that we thought would be the least controversial to the WCAG WG to include.  I looked at the Plain Language proposals and did my best to look at the needs identified by COGA TF, and craft language that I thought would be acceptable to the WCAG WG and be included in the first draft version of WCAG 2.1.

The wording is quite different, but in my opinion, addresses the needs identified.  I chose reading level, because it is internationally standardized, and there are automated tests already available.  When I look at Technique  G153: Making the text easier to read  https://www.w3.org/TR/WCAG20-TECHS/G153.html , it covers most of the items that the COGA TF identified.

Issue 30 Proposal:

Understandable Labels:  Navigation elements and form labels do not require reading ability greater than primary education level.  (A)  [link to WCAG’s definition of primary education level from UNESCO standard]

Issue 41:

Understandable Instructions:  Headings, error messages and instructions for completing tasks do not require reading ability greater than lower secondary education level.  (AA)  [link to WCAG’s definition of lower secondary level from UNESCO standard]

Delta 3.1.5 (rewrite of existing WCAG 3.1.5)

Understandable Content: Blocks of text either:  (AAA)

·        have a reading level no more advanced than lower secondary education, or

·        a version is provided that does not require reading ability more advanced than lower secondary education. [links to WCAG’s definitions of lower secondary education and blocks of text]
