it all depends on what you are wanting to accomplish with her and what you have already done with her... for example my colts are all sent to a trainer any more (I used to start all my own now Im too old and fragile to be tossed off lol) so I do all the ground work including ground driving etc... to the point of getting on them and I have an excellent relationship with my trainer and he knows he can just step on them when he gets them so he knows there isn't a lot of work for him to do other than stepping on so he gets them for 60days in the fall then they get turned out for the winter to think about what they learned, let them mature a bit and then they are ready for hard work in the spring which includes more of the finer points of training this is where you will have more advanced training depending on how you want your horse trained
