How much support you feel you need is at the discretion of you and your mentor. If you are teaching someone or running a practice for the first time, you might well appreciate your mentor being in the tower with you quite a lot to begin with, or you might be quite confident and happy with just the occasional visit.
Even though your mentor doesn’t need to be there every time you teach, they will need to look through your logbook and be prepared to witness the different aspects of your teaching required for accreditation. When you both feel happy with your level of teaching, you or your mentor can ask an ART Assessor to come and observe you teaching and then submit a recommendation for your accreditation.
You might find it easier to keep in touch via email or phone – send them your practice plan beforehand, explaining the exercises or methods that you’re going to ring and why. Then write up a little report – how it went, what you’d do differently next time and what worked well.
You can identify areas where a particular ringer is struggling with something and discuss this with your mentor, ask for feedback and suggestions if you’re stuck. Your mentor should be there as a supportive friend, as well as offering you constructive feedback.
