For study score prediction what is a “strong” cohort? How do you know the sacs will scale up? For example I go to a school whose median study score is 33 and has floated between 60-80th school in vic in the past few years. Although now it’s a bit higher than that. What would you (hypothetically) say about this?
I would say your cohort is likely to be well above average. However, the strength of the cohort can't really be based upon the school on it's own as the strength would differ for every subject. Although, the school strength is usually a good predictor of a cohort strength.
You can never be certain whether your sacs will scale up. It depends on the raw scores of the sacs for your cohort and your cohorts performance on the exam. In the instance, you have a so-called "strong" cohort with teacher's making easy sacs and a lot of people scoring high 90s and 100's it is possible sacs could scale down for some.
