TIMSS is reported on a scale of 0 to 1,000, with 500 set as the average score and standard deviation at 100. “Below low” represents students scoring less than 400; “low” represents students scoring from 400 to 474; “intermediate” represents students scoring from 475 to 549; “high” represents students scoring from 550 to 624; and “advanced” represents students scoring 625 or above.
