Competition identity

Read the qualification method before comparing times
World Athletics’ current rules distinguish Q for qualification by place in track events from q for qualification by time. The actual progression table states how many athletes move on and by which route. Do not assume that every distance or edition uses the same mixture.
Suppose a hypothetical round sends the first two from each heat plus two further athletes by time. A runner finishing second in a slower heat advances by place. A faster third-place runner may have to wait for the comparison with the other non-automatic qualifiers. The example explains that announced format; it is not a universal championship rule.
Field-event qualification uses the same letters differently
In a field qualification, Q indicates reaching the qualifying standard, while q indicates advancement by performance. Read the event legend rather than translating every Q as a heat placing. A throw or jump is not a race against the athletes shown on the same screen.
The qualification round establishes who enters the final. Its marks do not carry into the final as an opening lead. A hypothetical athlete throwing 70 metres in qualification and 68 in the final has a final performance of 68, not a combined 138-metre result.
A symbol is not a zero measurement
The current result-code table distinguishes DNS, DNF, DQ and NM: did not start, did not finish, disqualified and no valid trial recorded. Those describe different outcomes. NM is not a measured zero-metre performance and DNF is not proof that the athlete never started.
In high jump and pole vault, O records a valid trial, X a failed trial and a dash a passed trial. A passed attempt is a decision to omit that trial, not another failed jump. Read the sequence with its height headings before interpreting the eventual placing.
Compare marks within the correct round
A qualifying performance, a semifinal time and a final result remain separate records. A faster earlier performance does not itself award a higher final position. The championship’s final classification establishes the event placing.
For a hypothetical comparison, Athlete A runs 10.10 in a heat and 10.20 in the final, while Athlete B runs 10.15 and then 10.18. B has the faster final time. Selecting A’s best number from another round would answer a different question.
A world-ranking score is another calculation
World Athletics’ 2026 ranking explanation combines performance-related result scores with placing scores where applicable. It specifically distinguishes finals from heats and qualification rounds for placing-score purposes. That system is not simply the championship’s finishing list.
Use the event result for who finished ahead in that contest and the published ranking rules for ranking points. If an official result carries a disqualification or advancement annotation, retain it; a cropped time column can omit the decision that explains the classification.
Questions answered
Does Q always mean qualification by a track placing?
In track events it does; in field qualification it denotes reaching the standard.
Are qualification throws added to final throws?
No. Qualification performances are not part of the final.
Does NM mean the athlete recorded a zero-metre legal attempt?
No. It means no valid trial was recorded.
