! Interpret data with caution. Estimate is unstable because the standard error represents more than 30 percent of the estimate. |
NOTE: Both literacy and numeracy proficiency score boundaries are: Level 1 or below=0-225; Level 2=226-275; Level 3=276-325; Level 4=326-375; Level 5=376-500. Literacy and numeracy proficiency scores cannot be compared directly because each domain has a distinct framework, construct, set of items, and scale. Estimates based on U.S. combined data from 2012 and 2014. Detail may not sum to totals because of rounding. |
