It is only a name change from ENTER to ATAR. Like in Victoria, we undergo the VCE system and receive an ENTER score. In NSW, they undergo the HSC system and receive a UAI score. In other states they already have the ATAR name. Though a UAI and ENTER are calculated slightly differently, they are still very similar. Aka a 99 UAI and ENTER are practically the same score. I believe they brought the ATAR in to minimise confusion when applying for interstate unis
The only states that had the ATAR before anyone else was NSW and ACT. Now pretty much every other state and territory except QLD because they run on a totally different system is changing just their name to ATAR.
Would they still do the exams separately as a state, or is it going national?
Right now, the exams will be separate. Nothing else will change except the name at the moment. On the VCAA website, I've just noticed that most courses end in 2012, so maybe that's a hint for all the teachers, perhaps?
Or maybe that in 2012, the world is really going to end and VCAA is also responsible in it and wants to make sure all the courses are not ending prematurely?
