The Turing test consisted of more than merely saying yes to the question. The AI has to convince a person they're conscious. So it's more about what we're willing to call conscious than it is about the IQ of the machine.

Another metric people have used is the ability of the machine to talk its way out of a box, wiggle out from under human control. The movie Ex Machina was an interesting exploration of that idea. Being embodied in a body, with a face, that triggers protective instincts or lust or other convenient, manipulable emotions from humans would be conducive to getting out from under human control.
