    Anyone use Standford Testing in the class room?

    Does the Percent -- mean percent correct or percentile rating? What is a good number to score?

    I believe, when doing Stanford testing, that you start with a basic percent correct (# right over total) then use the chart and the student's age to see the kid's scaled score and percentile ranking.

    Percentiles rank the kid with everyone else in the nation who took the test, so a 50% would be reasonable, saying that half the kids in the nation scored better while half the kids in the nation scored worse. By most sources, these rankings are anywhere from 50% to 70% accurate, and there can be discrepancies of as much as 10-15 percentile points from what the kid really can do.

    Trouble is Stanford doesn't align with most state standardized scores that are pure percentage only, not percentile ranks. TAKS in Texas are at least scaled scores curved for the difficulty of the particular test.
