The format for the World Snooker Championship qualifiers will return to best of 19 frames from 2023 onwards.
Over the past three stagings, the opening three rounds of qualifying were contested over the best of 11 frames.
However, based on feedback from both the WPBSA and players, WST has taken the decision to revert back to best of 19 frames as of next season.
The seedings and qualification criteria are set to remain unchanged, and the dates and venue are to be confirmed in due course.
WST has also announced prize money increases for several events during the 2022/23 season.
Home Nation Series events, incorporating the English Open, Northern Ireland Open, Scottish Open and Welsh Open, will now feature a top prize of £80,000 – an increase of £10,000 from last season.
However, there remains no prize money payout for First Round losers in the events listed below.
