Strong Deduction covers 17 to 19 correct answers out of 25, or 65 to 79 percent.
At this level the multi-step chains mostly hold, and options that merely fit the story are usually turned down. The points that remain tend to sit in two places: statements that mix "some" with "no", where the conclusion depends on which groups overlap, and ordering puzzles with several fixed positions and one item left loose. The band is a percent-correct range on these 25 JobCannon questions only. It does not compare the taker with other people, and the test has no published norms.
Strengths
- Two- and three-step chains reach the conclusion without drifting away from the statements.
- Options that are only possible are separated from options that are forced in most questions.
- Reversed statements, such as "all A are B" read as "all B are A", are caught more often than not.
- Because most answers are right, an outlier among the four sub-scores is informative: one weak question type is easy to spot and to work on.
- The method is already in place, so simple sketches (circles for groups, a line for rankings) can tidy up what is left.
Growth Edges
- A "some" statement combined with a "no" statement supports a limited conclusion about part of a group, and it is easy to stretch it to the whole group.
- In an ordering puzzle, one item with no stated position gets quietly placed, producing a "certain" answer that the clues do not support.
- Counting questions, where two groups sit inside a total, call for "at least" and are sometimes answered with "exactly".
- Either-or and exactly-one-is-true problems need each case checked, and the search stops after the first case that works.
- Ordering puzzles take the longest of the four question types, and in a timed setting that is where the clock tends to run out.

Frequently Asked Questions
What does a Strong Deduction result mean?
It means 17 to 19 of the 25 questions were answered correctly, which is 65 to 79 percent. Most multi-step chains held, and the plausible-but-unforced options were mostly rejected. The band describes how the answers went on these JobCannon questions. It is a score range, not a ranking against other people, because the test has no comparison group.
Where do the remaining misses usually come from?
Mostly from two places. The first is statements that mix "some" and "no", where the safe conclusion covers only part of a group. The second is ordering puzzles with several fixed positions, where one loose item gets placed by assumption. Check the four sub-scores: if ordering and ranking is the lowest, start there.
Is it worth drawing diagrams at this level?
Yes, for groups and rankings. Overlapping circles make "some" visible and separate circles make "no" visible. For a ranking, write the items on a line and add one clue at a time, keeping a loose item off the line until a clue places it. A sketch costs a few seconds and saves the longer re-reads that careful readers tend to do.
Does this band say anything about job prospects?
No. This is an in-house test with no published norms and no formal reliability study, so it cannot say how a score relates to hiring or to performance in a job. The roles listed on this page are ones where checking that a conclusion follows from stated rules is part of the work. They are examples to explore, not a forecast.
