The IIHF's official final rankings of the tournament:
The Division I A tournament was played April 19 to 25, 2015. Ukraine was to host the tournament, with some matches in Donetsk, but withdrew in advance due to "the political tension in the country being an obstacle for foreign visitors and fans who want to visit the ice festival in Donetsk." On 18 September 2014, it was announced that the tournament would be hosted in Kraków, Poland.
