The Core Contest is a six-week contest focusing on improving Wikipedia's most important and most viewed articles. Prizes in the form of electronic store vouchers will be awarded.

The next (8th) running was held over six weeks from 00:01 UTC 15 May to 23:59 UTC 30 June 2017… entries listed at Wikipedia:The Core Contest/Entries. Congrats to Maunus for their winning entry, Aztec. Cas Liber (talk · contribs) 19:48, 14 November 2017 (UTC)

The Core Contest, a noble pursuit organised by Danny (talk · contribs) in 2007, was revived in March 2012. A short, intensive contest, the idea is to focus on improving Wikipedia's most important articles, particularly those in the worst state of disrepair.


As Wikipedia has evolved and become more detailed and polished, so have its criteria for featured and good-article status become more rigorous. I do think this is a good thing as after eight years of these processes we are now producing an ever expanding portfolio of material that actually looks like it could appear in a published tome. However, one side effect is the rigour of the process favours the production of more esoteric/narrow/specialised good and featured content. What to do? I have always preferred carrots to sticks, and so thought of reviving this competition:


The aim of the contest is to encourage a short, sharp burst of activity and article improvement in the vital or core articles. Editors are also welcome to improve and nominate an improvement to a broad or important article which lies outside these two lists as long as they can provide a rationale as to why their article should be considered. The lists provided are a guide only. Furthermore, a priority is to improve those core articles in the worst state of disrepair, expanded upon below:

  • The article improvement process takes place over one and a half months, during which time an editor or editors knuckle down and improve an article, and submit a diff of their work at Wikipedia:The Core Contest/Entries (scroll down to Wikipedia:The Core Contest/Entries#List of contest entries to get an idea).
  • The broader or more "core" an article is, the greater weight it will be accorded in scoring. The general pool should come from Wikipedia:Vital articles or Wikipedia:The Core Contest/Articles. Anyone willing to tackle one of the top-tier vital articles will gain much kudos for it. Other broad articles can be nominated, as it is highly likely some important and broad material is missing from one of the two lists above (i.e. any editor is welcome to nominate any article and if they can put a good case as to why it should be considered, we'll certainly listen).
  • During this period, prizes will be 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) 10–50% sourced with reliable sources, will be valued more highly than one from (say) 50–90% sourced.
  • As judges review entries, they will post feedback on the improvements and areas still to improve before future good article nomination or featured article candidacy.
  • Current featured articles are not eligible. Good articles are, but you might have a tough time showing radical improvement in a GA, which would most likely be dwarfed by massive improvement in a start-class article. (Note that the good- and featured-article process are not considered part of the Core Contest, which is judged independently.)
  • The judges will weigh up the improvement of the article, combined with its "core-ness", to come up with a "best additive encyclopedic value" to Wikipedia.

Past competitions[edit]

The Core Contest proper has been run on six occasions: November 25, 2007 – December 9, 2007, March 10–31, 2012, which saw £250 in Amazon vouchers shared by six editors, in August 2012, which saw £250 in Amazon vouchers shared by seven editors, April 2013, which saw £250 in Amazon vouchers shared by three editors, in 10 February – 9 March 2014, which saw £250 in Amazon vouchers shared by five editors, 1 March – 14 April 2015, which saw £250 in Amazon vouchers shared by three editors, and 15 May - 30 June 2016, which saw £250 in Amazon vouchers shared by five editors.
Danny's contest (3rd incarnation), held from September until October 7, 2006, was a precursor to the Core Contest. A total of $170 of Amazon vouchers were awarded to three editors. The first and second incarnations focussed on new articles while the third looked at building core content.

All the winners of the various contests are listed here.
