The SEM represents a range of scores within which a test taker's true score can be found. Test result certificates include 'Your score range' which represents the standard error of measurement (SEM). All five scores are estimated independently and are weighted combinations of the questions that contribute to the score. The overall score is not an average of the sub scores. Test results include an overall score as well as sub scores of Literacy, Conversation, Comprehension, and Production.
