[@Ezmeralda] To phrase it better- the war's been going on for over a century now, and sending out the untrained Aes Sedai risks losing invaluable assets. It only makes sense that the White Tower would wait for an Aes Sedai to reach their full potential before sending them out into battle, lest they risk an untimely and ultimately preventable demise.

It is possible that a kingdom/city/army is being preassured badly by the dark forces, that her training would be continued on the field by a mentor. Behind the safety of a front line.
