I agree, "School is about excellence and doing your best".
However, I don't see the concept of standardisation as being a problem. What you are talking about was, in fact, "fairness" in grading. If we try to be "fair", then we add compensatory marks for one's homelife, lack of opportunity, degree of effort, financial standing, etc, etc.. That would be "fair", but not educationally sound if wanting to compare apples with apples. After-all, what can the kid actually do?
We need baseline criteria, but this is an impossible ask in many areas of learning, especially the creative arts, of which English is but one. So it always comes down to airy-fairy statements that are neither helpful to the student, nor helpful to the teacher. People forget that teaching is an art, as well as a science. There are just way too many variables to account for, when trying to determine criteria. It will be interesting to see what 'they' come up with!
IMO, MCJ forums over the past 10 years have not provided us with sufficient understanding of commonality of judgements, (I'm happy to be corrected, if that is not the case!) so I don't see how National statements will do it!
Standardisation is a result of our shrinking world and global influences - once upon a time, we only needed to compare ourselves in our local village/state, but now we are on a national, if not world, stage.
Standardisation could lead to MORE litigation, if schools fail to show how the needs of individual learners are catered for. I firmly believe mass education, as is currently the govt system, fails to deliver to students what govts espouse teachers should do - teach to individual needs. Until we get the same resourcing as Kindy, Pre-primary or ESCs, we don't stand a chance of doing that!
