How do you analyze a skills gap when you are changing careers?

O*NET defines tasks as specific work activities that can be unique for each occupation, and its duties search covers over 19,000 task statements (E21). A gap is a task on the target occupation that your record does not yet show. It is not a mood, and it is not a percentage of "readiness."

This page used to say career changers routinely underestimate transferable skills. That was not sourced. It is cut.

Open the O*NET summary for the target occupation and read the task list. For each task, write one of three notes: I have done this, and here is the line; I have done a piece of it; I have not done it. Keep the line in your words, with the tool and the outcome.

Adjacent work counts when the task matches. A title match is optional. Do not copy a task statement onto your resume unless you did that work.

Say so. A posting that requires it is a real gap. You can close it with a small piece of work you can show, or you can apply where that task is not required. Pretending the gap is a wording problem is how polish gets ahead of proof.

If public data says the occupation is shrinking, say that plainly and look at which of your tasks show up in occupations that are not. The task check is the place for that reading. It does not assign you a personal risk percentage.

Take one posting in the new field and run Job Match (5 tokens). You will see the requirements your current record proves and the ones it does not. That list is the gap.
