The Contest has run over three weeks from midnight March 10 to midnight March 31 Sydney time (9PM on Friday 9 March in London, 8AM on Friday 9 March in New York). Although the period of active editing time has ended, editors can submit material they improved in the three week period below.
- During this period, prizes were awarded to the best article improvement of a large/broad/important article. Improvement will be quantified and compared — in cases of similar levels of improvement, articles in a worse state to begin with will be deemed more valuable, all other parameters being equal. Thus an article that has gone from (say) 10% to 50% sourced with reliable sources, will be valued more highly than one from (say) 50% to 90% sourced.
- As judges reviewed entries, they posted feedback on the improvements and areas still to improve before future Good Article nomination or Featured Article Candidacy.
- Current Featured Articles were not eligible. Good Articles were but one might have a tough time showing radical improvement in one, which might outweigh the massive improvement of a Start-class article. (Note that the Good and Featured Article process are not considered part of this, which is judged independently.)
- The judges weighed up the improvement of the article combined with its "core-ness" to come up with a "best additive encyclopedic value" to Wikipedia. The winners were announced at Wikipedia:The Core Contest/Winners
