Hello friends,
What is a good SEM score?
Scores can range from 400 to 500. * SEM is the Standard Error of Measurement that reflects the inherent error that is a part of any testing process. ... If you were to take any number of tests equivalent to this one, your score would fall within this range with a statistical confidence level of 95%.
Most typical confidence intervals are 68%, 90%, or 95%. Respectively, these bands may be interpreted as the range within which a person's “true” score can be found 68%, 90%, or 95% of the time. It is not possible to construct a confidence interval within which an examinee's true score is absolutely certain to lie.

The standard error of measurement is a function of both the standard deviation of observed scores and the reliability of the test. When the test is perfectly reliable, the standard error of measurement equals 0.

What is a good SEM score?
Most typical confidence intervals are 68%, 90%, or 95%. Respectively, these bands may be interpreted as the range within which a person's “true” score can be found 68%, 90%, or 95% of the time. It is not possible to construct a confidence interval within which an examinee's true score is absolutely certain to lie.
For example, if a student receivedan observed score of 25 on an achievement test with an SEM of 2, the student canbe about 95% (or ±2 SEMs) confident that his true score falls between 21and 29 (25 ± (2 + 2, 4)). He can be about 99% (or ±3 SEMs) certainthat his true score falls between 19 and 31.
The SEM quantifies how far your estimate of the mean is likely to be from the true population mean. So smaller means more precise / accurate. In that sense, SEM=1.5 indicates that your sample mean is a more accurate estimate of the population mean than if SEM was 3.5.
The standard error of measurement is a function of both the standard deviation of observed scores and the reliability of the test. When the test is perfectly reliable, the standard error of measurement equals 0.
SEM score above 50% are treated as good for successful marketing campaign.
