It seems to me that you are asking how to assess your progress with your dog. A bunch of questions occur to me:
1) How experienced a handler/trainer were you when you met her? Had you trained a dog in any other dog sport, like AKC obedience or Agility? As you've doubtless figured out by now, training a SchH dog is a very tricky balancing act. Speaking only for myself, it took me a lot of years and several dogs to feel as if I knew what I was doing. Are YOU learning and making progress? Do you see things now that you couldn't see when you started out? Can you begin to see things from your dog's POV? Do you have a better theoretical understanding of how your dog learns her exercises? If you can give even a qualified "yes" to any of these questions, then IMO you're on your way to being a trainer.
2) How drivey, stable, and talented is your dog? Unless all the dogs in your group have common genetics, you've doubtless seen a range of temperaments and talents among the dogs your friends train (and even among litter mates there is considerable variation). Where does your dog fit into this range? If your dog has drive to burn, is completely social, stable and confident, and has a natural full, hard grip, then she probably should be near the "top of her class." If, on the other hand (paw?), there are some holes, well, those sometimes take a while to work through.
3) What was your dog doing those 7 1/2 months between weaning and coming to live with you? Did she arrive confident, with good social skills and her drives developed? If she didn't, how long did it take you to get her to the ground floor? If you're comparing the time to train a puppy to SchH 1, I'm not sure that you should count the time spent fixing a deprived childhood.
Let me add that, for me, the 1st few months are critical. Doing what should have been done in the 1st few months as the pup is entering adolesence is way harder! Kudos for being patient enough to do it.
4) If your female has not been spayed, then in the 24 months you've been training, she's probably been in season at least 3 times. In my experience (2 females titled) they are loopy for at least a month each time. Yes, they can work, and I've seen some well trained ones do well in high level competition (Lori Cruiser's female at last year's AWDF, for example), but as a rule, they don't learn much while all that is going on.
So subtract the time for remedial work, and for heat cycles, and I'll bet you're closer to 16 months than 24.
5) A politically touchy subject, but I'll bring it up anyway. What standard are you looking for in protection? I hate to say it, but there are clubs where a dog who can be persuaded to hang onto a puppy sleeve with his canines, who doesn't run off the obedience field, and who can find his way to the end of a track will earn his titles. I hope that your club isn't like that, and you're training for correct work on correct, strong helpers. Remember, the title means nothing to the dog. Knowing that you did the work so that your dog really earned her title will make you very proud of both of you.
And, on the subject of your club, are the other dogs in club making progress? Have some of your friends earned new titles on HOT dogs? Particularly in protection is there one recipe for every dog, or does the TD tailor his work for each individual dog?
This has gotten awful long, so I'll close by observing that you've already gone from nothing to a BH as (I assume) a novice handler. And it sounds as if you and your dog are well on your way to SchH 1.
And remember, it's not the destination, it's the journey.
