GCW Test Requirements

Further to my last article about the Guild of Canadian Weavers, dateline 07/01/98, this is a brief overview of the Guild’s Test Requirements for obtaining the Master Weaver certification. A major focus of the GCW is “to prepare and set examinations at designated periods for the benefit of those wishing to qualify for the 4 stages of regular membership in the guild.”

The tests are divided into 4 sections. Each level must be completed successfully, before proceeding to the following level. Completed projects are submitted for marking twice per year, in April and September to the Test Administrator. The tests are then sent to judges located in another province, to maintain confidentiality and fairness in marking.

A brief summary of the projects follows. Full details of the test program are included in your information package upon joining the Guild.
