its a rather hard subject to organise... firstly you need adequate facilites.
A sprung floor ... God my school didn't have one, we were dancing on hard concrete until Late July, just before the exams when the UNSW dance department let us use their halls for our final weeks of practice... so in other words, we learnt all of our Jumping and stuff in the last couple of weeeks
Your school has to have a 'GOOD" dance teacher - who is really patient, willing to work longer hours than most- if students need extra performance practice.. is willing to go to as much effort as needed to get students through HSC..
I mean, our teacher... since we didn't have a adequate dance studio at our school she took us on SUNDAYS all day on Sunday, sometimes saturdays as well (from about March onwards until the HSC ) Every single week as well as Scheduled Dance class times- to a dance studio in the city so we could rehearse for our perfromance exam, and we didn't even have to pay for it... She got her friends which are also dance teachers to come and help us as well .. .
I mean, working on the freaking Weekends with 6 dance students is really generous.. taking a whole day, sometimes two out of her weekend for Free.
Your school needs to be prepared for the examination shcedule, wether they are willing to give you time out of class to practice in August when exams are..
there is alot of reasons why your school might not offer it, to be able to teach dance.. you have to be highly skilled in the art, as well as knowing how to treat any injuries.. etc.
