I think when you're looking at the levels of adjustments, you would look at that frequency range and intensity of the adjustments. So obviously to go from a supplementary to a substantial level of adjustment, what you would be indicating there is that the frequency of the adjustments have increased, the range of adjustments that you are providing has increased. And the intensity of providing those adjustments has increased. So you would think that as a student changes or moves to a different level, the amount of evidence that you have collated would reflect that. So I would imagine that if you had a student on extensive or substantial, you are then indicating that it's a high-level of frequency, a high-range, and high-intensity. Therefore your amount of evidence would be higher than perhaps a student on supplementary or quality differentiated teaching practice. So you need to make sure that even if you're imputing a disability, that you have evidence of the four types that you need. So that would be needs being assessed, adjustments being provided, consultation and collaboration and monitoring and review.
