Levels of Bench Jeweler
Having some definition of the desirable skills to master at each level will assist all mentors in guiding their mentees to useful outcomes. When JA designed the Certified Bench Jeweler program, extremely important work was done to define the various levels of jeweler skill. Today, the JA no longer offers that program. But using the JA Professional Certification tests as guides, we have identified the following expectations for each professional jeweler level. These are just guidelines. You will have your own, important ideas about how to guide your mentees. After all, the nature of one-on-one mentoring is that the mentor also brings tremendous personal experience and opinions to the process.
But we believe general guidelines are an important way to help you to develop a personal program. After all, sometimes the hardest part of mentoring is just getting started!
By using the "expectations" below, you will have things to discuss every time you talk with your mentee. You may suggest a project out of an Alan Revere book, or a video you put on Youtube, or a project outline you once received when you were a student, or a few pages from Oppi Untracht's book . . . and we look forward to creating ways for mentors to share with and support one another, so the best resources for each skill level can be shared and known!
