A method, a computer implemented method, and a device, all for adaptively testing a subject's neurological state. The method comprising the steps of: administering one or more seed questions; obtaining one or more answer(s) to the one or more seed questions; calculating a score value of a latent subject trait from the answers to the one or more seed questions; the method comprising an adaptive test loop, comprising: (a) selecting, based on the score value, one or more further questions from a bank of questions; (b) administering the one or more further questions to the subject; (c) updating the score value based on the answers to the one or more further questions; (d) determining whether a test completion criteria has been met; wherein the method repeats steps (a) - (d) in sequence until the test completion criteria has been met, and provides an output of the test based on the score value which is indicative of the subject's neurological state.
