培训的结果就是Diploma of Building and Construction（CPC50210），一般的情况是TAFE上两年full time的课，现在也有了online的可以选择。实际的工作经验基本对各种情况要求不一样，有的要求7年有的要求5年，而且这工作经验的细节也不一样，有的要求不能是管理岗位，不能是设计，只能是实际操作的建造工作，有的则允许是工程管理岗位。还有要求是皇家建筑师协会等的会员的，这种显然不适合新到澳洲的试图进入这行业的人，只对当地人有参考意义。
总共有set1到set5几种情况：

•Form 05 Building practitioner set 1 initial application

为此，抛砖完毕，提出我的问题：
builder registration究竟是否必须要diploma of building and construction？从5个set看有多个都不需要，而是需要参加一个Board examination。当然这个考试也是针对对diploma学的那些内容的，如果是牛人，不学这个课或者自学也能考过。那么，学这个course对builder registration究竟有没有意义？
