NCE Scores

  • NCE stands for Normal Curve Equivalent scale and was developed by the Department of Education
  • NCE has a mean of 50 and a standard deviation of 21.06 which allows for the 1st percentile to achieve an NCE score of 1 and the 99th percentile equivalent to an NCE score of 99.
  • NCE = 21.06z + 50

  • The scale is somewhat archaic and confusing but required for many Department of Education reports, grants, projects and evaluations.
