Phil,

To the degree that competencies are modeled by CASE, I can definitely say that there is always a creator of the framework.

Phil,

I’m coming in late to the conversation, and I’m probably not understanding that context, but I thought I would chime in anyway, just in case.  The statement below caught my attention:

A credential can be offered by an EducationalOrganization but a competency cannot be.
Are we suggesting that, per the way schemas are currently setup, an EducationalOrganization cannot offer competencies in lieu of credentials?  If so, that strikes me as potentially limiting and not necessarily reflective of where the field is going.

Hi Jason

an EducationalOrganization can run a course or program, or create a learning resource that teaches a competency.

they can issue a credential that recognizes that competency

Organizations can offer assessments that assess competencies, and if passed lead to the award of credentials.

I am not sure if by 'offer a competency' you mean something other than variations on that theme.

In T3 and in our other work, employers, for instance, are increasingly interested in competency-based hiring outside of credentialing.  Competencies are increasingly needed to stand alone so employer, education providers, workforce trainers, and others, can offer competencies as part of a learner or worker record.  This is also consistent with where the university registrars are going in the U.S.  From where the Chamber stands, credentials can include competencies, but competencies are not exclusively found in a credential.


Yes, the model has Credentials and Competencies both as first-class stand-alone entities, with the provision for a Credential to require a Competency
Not sure if my comments add value given where the conversation was going, but in order for us to support innovations in the talent marketplace, we need a data infrastructure that makes this distinction clear.  Happy to walk this back if I’m off track.

Let me know if I'm missing anything, or if you have any questions.

My understanding of CTDL is that it only models Credentials as Achievement Descriptions, and does not include models for PII Assertion Records.

  While a relativist view could assert that the any distinction could be semantic and change in context, I continue to assert that there is a hard logical distinction between Achievement and Assertion,

True, but they can be modeled with similar terms. There is a hard logical distinction between a Person and a Book, but they both have a name. There is a logical distinction between a TextBook and a Course, but many of their properties and attributes are the same. Achievement and Assertion can be modeled as different profiles drawn from the same term set.
but not between Competency and Credential.
  While it is true that Credentials can have Competencies, they are in fact the same class of entity and often have recursive associations between them.

With the simple distinction that a credential can require a competency but a competency cannot require a credential.

A credential can be offered by an EducationalOrganization but a competency cannot be.

Outside of learner records, credentials and competencies are quite different.

Phil

In short:

Achievement Description types include Credentials, Competencies, Skills.  While historically different in some contexts, increasingly these terms are blurred and there is no logical/structural difference between them.

Achievement Assertions can refer to Achievement Descriptions and include specific PII information about the Learner and Issuer, and can include specific instance information like Evidence, Endorsement, Result, and Verification.

Subject: Re: Domain sketch


I agree mostly with Alex (and Stuart's reply). I want to add some consideration of context into the mix and think about reuse of terms in different contexts (which is how schema.org works).

In short, I think the distinction between assertions and descriptions comes from putting circles around different parts of the domain sketch (different profiles of the same set of terms, if you prefer). This is part of what I mean when I say that it is not a domain model because there are different perspectives on it. I think what Alex describes is one (valid) set of perspectives.

In achievement descriptions, competency is separated from credential in most of the work that we are following (CTDL, OpenBadges BadgeClass, ESCO etc.), and it needs to be. When describing an EducationalOccupationalCredential you need to be able to say what competencies are being credentialed. That's why the competencyRequired property of EducationalOccupationalCredential got into schema.org.

It's also useful to separate competencies from credentials when describing learning resources. Then it is necessary to be able to show an alignment to a learning objective (i.e. a competence) separately from credentials, in order to promote reuse in different contexts.

But in other contexts the schema.org classes can be used as part of an assertion. I don't think anyone is doing this in schema.org, but if I were to write, as part of a JSON-LD CV (and I'm making up a couple of properties):

{

   },

   "hasSkill": "Educational metadata modeling"   //a literal representing a competence, could be DefinedTerm

}

then I am making achievement assertions. (And in order to make these assertions verifiable you would have to wrap them up into some collection of assertions and provide the means of verification.)

I agree with Alex that
Once you have a record that matches a person with a "competency" or "achievement description", and "evidence" or "assertion" from an "approved" organization that that person has either passed an assessment or done something that shows that... you have an "achievement assertion"

But not with
or "credential".

As Stuart says, to date in schema.org the EducationalOccupationalCredential class has been used to represent a credential offered (something that "may be awarded") in the sense of being the thing that the University of Bristol says I can sign up to if I want to study for a PhD in physics, not the specific PhD that I hold. So this is an example of a EducationalOccupationalCredential that is not an achievement assertion:

{

I agree with Greg that the distinction between the "achievement description" and the "achievement assertion" is critical, but in this case I think we are once again running aground on the semantic reefs.

If we think of an "achievement description" as a description of a Knowledge, Skill, Aptitude, or Experience (either inside of some taxonomy or not) then it matches cleanly what most people mean by competency.

It typically does not include the assessment or test that would "prove" "provide evidence" that that competency exists with some person.  That matches with what people usually refer to as an "assessment" or "evidence".

Once you have a record that matches a person with a "competency" or "achievement description", and "evidence" or "assertion" from an "approved" organization that that person has either passed an assessment or done something that shows that... you have an "achievement assertion" or "credential".

I think it is that simple.  :-)    Now - I know each of these categories have hierarchies and taxonomies and differing levels of granularity and different ways t o represent an assessment or organizations trustworthiness  or authority, but this model can be represented by what Phil is describing.

What am I missing?   I see no issue with the following semantic equivalences:
competency <-> achievement  description
assessment <-> evidence (I understand that not all evidence takes the form of a "test" but you are assessing somehow!)
credential <-> achievement assertion

Friends,

I challenge the aspect of the model that separates a competency from credential.  I believe that both credentials as expressed by CTDL and competencies as CASE (as well as badges and micro-credentials) are all overlapping labels and structures for expressing the general Achievement Description.  Degree, credential, micro-credential, badge, skill, knowledge, ability, course objective, academic standard, and learning target are all labels for this concept without accepted boundaries between them and distinctions.  The more important distinction from an information architecture standpoint is separation of the general, linked-data public Achievement Description from the Achievement Assertion that contains PII data about the Learner:

Subject: Domain sketch


Hello all, I got a little feedback about the domain sketch that I've shown a couple of times, and have altered it accordingly, and tried to clarify what is and isn't currently in schema.org<https://nam02.safelinks.protection.outlook.com/?url=http%3A%2F%2Fschema.org&data=01%7C01%7CGNADEAU%40PCGUS.COM%7Cd0014cf011924f5d1cbc08d724d118e2%7Cd9b110c34c254379b97ae248938cc17b%7C0&sdata=2uLTGaQpRF2Ft6G6Mmjk13npsbL1jn0h49it5h7UBDA%3D&reserved=0>.

Here it is again. I'm thinking about putting it on the wiki, and hoping that, along with the issue list<https://nam02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.w3.org%2Fcommunity%2Ftalent-signal%2Fwiki%2FIssues%2C_use_cases_and_requirements%23Issues_open_for_consideration&data=01%7C01%7CGNADEAU%40PCGUS.COM%7Cd0014cf011924f5d1cbc08d724d118e2%7Cd9b110c34c254379b97ae248938cc17b%7C0&sdata=N8EwQ7h3SZZ3z3rVs9bBmLZkKqe9aH7ur2BPOjO9di0%3D&reserved=0>, it might serve as a useful way of introducing what we are about and what we are doing.

[cid:image003.jpg@01D55699.5D17E610]

I really want to stress that it is not intended to be a complete or formal domain model, nor is it intended to be prescriptive. (I think that for a domain as big as this, with so many possible perspectives, it is premature to try to get consensus on a complete formal model now, if indeed that will ever be possible.)

I would welcome feedback on whether this sketch helps, and how it might be improved, what needs further explanation, or anything else.
