World English-Language Scrabble Players Association (WESPA) has recommended that the dictionary be used on all WESPA-rated events with effective from 1 July 2019. HKSPA, as the national association representing Hong Kong and as a member association of WESPA, has decided to follow WESPA in adopting CSW19 as the official tournament word list for tournaments rated or recognised by HKSPA starting from 1 July 2019. CSW19 will supersede the use of CSW15 dictionary. Competitions before 1 July 2019 may follow either CSW15 or CSW19 at the discretion of the organiser, subject to approval by HKSPA.
As on 16 May 2019, the first HKSPA-rated tournament to use CSW19 as the dictionary will be the CCC Mong Man Wai College 10th Inter-School Scrabble Tournament (2019) on 29 June 2019. On the same day, the last HKSPA-recognised tournament to use CSW15 as the dictionary will be held, namely the 6th Shatin Inter-School Scrabble Competition (2019).
