I did a round of training this week in preparation for our audit on Monday. Filling out the training matrix I noticed a lot of empty squares in my own column. How can I effectively show my own competency? I cannot easily spare the time and don't want the business to waste the money for me to go to seminars, etc.
You're probably already into your audit at this point.
However, if you have any previous certifications that you can show or training documentation that you have created for the company, those can often suffice. If there is any lab testing you are in charge of, you can do round robins (ring testing) with trained analysts and/or outside laboratories to show proficiency in those areas.
