A. Every referee will be required to take the theory test from Level 0 through to Level 5. WSO will work with the member nations to ensure the practical appraisal is conducted on appropriate matches. Squash TV / video evidence will be used to ensure referees are aligned to the new standard. Retrospective matches from January 2019 through to up to date matches may be used as evidence of competency. These matches will be appraised by an approved WSO appraiser. Feedback from all sources will be sought to confirm competency for the respective level. Due to the level of work required it may take time to migrate all information.
