Inconsistencies of ATAR calculators for standard english (1 Viewer)

[Sindivyn]

After playing around with the ATAR calculators for English (Dux, Matrix, Einstein, HSCatarcalculator), anything greater than 85ish produced very different results. Is there any scaling data on this?? The scaling report seemed quite limited (top 1% only, even though this region is roughly the top 0.5-0.1%).

For a full list of how the subjects are scaled in 2011 see

Page 32

Also see

This is all data for scaling. The calculators base it of here.


P.S when you check for years, are you ensuring that you check all for the same year? Some calculators can do different years.
P.S.S In standard English, less than 1% of the state get above band 5. So really, you can't be that exact when you get such small numbers.

Yeah, made sure they were 2011 - the report shows a large gap between max mark and p99 (47 to 38 - unlike most other subjects) - does this mean that ATAR calculators are speculating on it?
Actually, the table on page 36 is quite helpful, never saw it before. Top 0.1% get scaled marks > 45 per unit. Assuming the percentiles provided are correct (they actually match), does it mean that Dux is the only accurate calculator for standard english?
For example, 90 in standard on both calculators P99.
However, Dux gives 45.99 per unit (compatible with the table) whereas Matrix gives 42.27 per unit (incompatible with the table).

There is a large gap.

Only about 16 of all standard students in the state obtain a band 6.

I thought that number jumped to 60-70?
