Coming out and asking what you’re not testing is disrespectful IMO for the reasons you state. But there’s a way to do it with how it’s worded and the delivery. We can’t have tone of voice here, so that’s not going to come across.
Rather than asking “why am I not testing?” one could ask the requirements for testing, such as time in grade/minimum number of classes. Sometimes the student may be ready from a syllabus standpoint, it they haven’t reached that requirement. I remember about 2 years ago asking myself why I wasn’t invited to test. I thought I had the minimum number of classes fulfilled, but I didn’t; the requirement jumped from 30 to 60 classes since the last grade, and I was in the low 40s. It made sense after I saw it written in the syllabus.
One could ask the CI what they need to improve on in order to test, what are the requirements to test, etc. That’s along the lines of why they’re not testing, but not an accusatory, disrespectful, asking to test, etc. way of going about it.
A student should be able to ask what they need to improve on. They should be able to ask what they need to do to promote. There’s a way to do it without challenging the CI. I’m not sure if anything I write would come across the correct way because there’s no tone, body language nor full context.
I’ve asked my teacher about promoting a few times, and he’s never given me the impression that I asked the wrong way. The last time I asked him, I remember starting the conversation with “I’m not asking to promote, and I don’t think I’m ready to promote yet...” This was about a week or so before a scheduled test in the dojo (that I wasn’t invited to test during). I basically asked him what’s on the syllabus and the time requirements. I wasn’t quite there yet with minimum classes (but I was pretty close) and I was still somewhat recovering from a 3 month long illness (Lyme disease). He told me he planned on testing me next time (which was 2 months away) because I was still having a difficult time recovering from Lyme and he didn’t want me pushing it too soon. Had it not been for the Lyme, he said he would’ve asked me to test at that time. I completely respected that and agreed. So I guess you could say I was asking why I wasn’t promoting, in a sense, but that’s not really what it was.
