I believe everyone is tested. The Seanchan don't know anything about sparkers and learners. I am also not certain if the a'dam is capable of detecting a sparker until she is very near to the channeling age. I expect that putting the a'dam on a 5 year old sparker would do very little for instance. So in order to be certain, you need to test until 25th after which women no longer spark. The Seanchan likely won't understand the reason (though they might have once at the very beginning), but they know that after 25th any woman who will start channeling, has already done so.



Well, the testing is done only once per year. I suppose there is a small chance that you start sparking right after the last test and die before the next one. But I expect that for the most part you are right.

Not that I find that comforting. Between a relatively quick death via OP or horrific-torture&lifetime of being viewed as little more than an animal, I would not have to think long to choose the option which I would prefer.



I seem to recall a mention somewhere that some are like that, while others fight against it. Makes sense in a way, no matter how brainwashed you are, when the moment actually comes and you are suddenly a slave and an "animal", you will not like it, no matter how much you supported the system before.
