Across 22 meta-analyses, self-evaluations of ability correlate with objective performance at about r = .29 — real but moderate. This is why Part 2 decides emphasis only, never whether a learner may proceed.
Self-rating is least accurate exactly where this project works — among people with the least experience of the domain. Part 3 exists as the counterweight, because it asks what somebody would do rather than what they think of themselves.
Situational judgement tests predict job performance at ρ = .34 across 102 coefficients and 10,640 people. That is the evidence behind Part 3, and behind writing the wrong options to be plausible rather than silly.
Interest relates to both performance and persistence. For learners who choose whether to continue, what somebody wants matters as much as what they can already do — which is why Part 1 comes first, and why it opens with wants rather than gaps.
Longer questionnaires lower participation, and answers late in a long instrument are measurably worse. The partner draft ran to 75 items; an abandoned questionnaire yields nothing, so this one is 28.
It is a routing and starting-point tool, not a test, a qualification, an aptitude measure or a filter. Nothing is marked, no path is closed, and every path begins at Lesson 1 whatever the result. Eight goal questions cannot capture a working life; somebody with a clear preference the tool did not ask about should follow it. The Part 3 situations are drawn from the ReSTART courses, so they favour a learner who has already met that material — and at intake, nobody has. A trainer should treat the result as the start of a conversation, not its conclusion.
