Standard Error of Measurement (SEM)*

SEM refers to the standard deviation of test scores that would have been obtained from a single student had that student been tested multiple times.  It is a measure of the variation of scores that would be expected if the student had been tested repeatedly.  

This information is of interest to parents who might wish to apply the following SEM to their child's performance for this year.   In order to be easily referenced, the SEMs below are reported by grade level and content area.

NOTE: In future years SEM will be posted respectively.
