Squizzed quiz now feeding into monthly rankings     11/Jan/2019


Squizzed has been added as an IQO ranking event!


At the last AGM we agreed to start using the monthly Squizzed quiz -  - as a qualifying event for the Irish rankings, once we'd done some analysis to check that the difficulty level and consistency of Squizzed is similar to the Hot 100. This has been checked and found to be consistent.


So from the 2019 #1 edition onwards, Squizzed scores will be included in the rankings.


If you're interested in sitting this quiz wherever you are, see the original announcement for details of how to take part, and watch out for IQO-organised venues announced on our website & social media.


For Dublin people, the next edition will be on Tue 29th January.




John O'Sullivan RIP     19/Sep/2018


It is with great sadness that the IQO announces the sudden death of our quizzing colleague John O'Sullivan. John was a dedicated member of the IQO committee from the organisation's founding in 2012 to the present day, and made many valuable contributions to the IQO's work.


The IQO extends its sincere sympathies to John’s family and many friends, particularly his son Colm who is a former IQO committee member.
