"adjusted upwards by one standard error of measurement"
I don't claim myself an authority on test measurements. However, in my opinion, 'standard error' is a statistical usage. No GATB or no IQ test even can measure your potentials and capabilities with all out mathematical equations. There are always chances of errors. Furthermore, to normalize the raw results, the psychologists have to use 'standard error of measurement' to avoid confusions. It may be adjusted upward or downside depending your scoring. Suppose you get a score of 100 in an IQ test and it may be read as 90 or 110 depending upon your performance in given parameters. The normalized results are interpreted as per requirements of the employer or the subjects.
