Hi Sheridan,
At StAC we built a 'predictive' tool, which was really a manual analysis of student performance over a period of time and comparing results from Yr13 Scholarship performance and looking backwards at how those students had performed in Yr9 MidYis testing (Which I know not all schools do).
This proved remarkably accurate (although perhaps not surprising).... I can't recall the specifics, but it was something like if a student scored approx 130 or above in a given MidYis test . then it would mark them as a likely successful scholarship candidate in Yr13.... again, not hugely sophisticated but gave Deans etc a chance to shoulder tap kids in advance to encourage them to perhaps have a crack at Scholarship in Yr12 as a good prep for concerted effort in Yr13. Usual caveats apply of not reading too much into a one off test/exam performance.
Here are two examples:
STUDENT A (squeaks into A band mIdYis but unlikely to be a strong scholarship candidate, but consistent Excellence in Yr11/12)
Vocabulary 111 A Band
Maths 107 B Band
Skills 100 B Band
Non Verbal Skills 115 A Band
Overall 112 A Band
(A Band starts at 110)
STUDENT B (finished with 5 scholarships, 2 outstanding in Yr13)
Vocabulary 131 A Band
Maths 138 A Band
Skills 115 A Band
Non-verbal skills 142 A Band
Overall 139 A Band
MidYis is an interesting standardized test that is repeated in Yr10 (and I think Yr11) to try to determine a 'value add' score, but you do have to pay to get students sitting it.
Cheers
