Following are D.C. charter schools' NCE scores in math and reading on the Stanford 9 test administered in April 2002. The NCE, or normal curve equivalent, score is similar to a percentile score and shows how a school's performance compares with the national average. The average NCE score for the nation is roughly 50.
The results below were released by the D.C. public school system in its capacity as a state education agency, and they differ somewhat from the scores release by the D.C. Public Charter School Board for the schools it oversees. One reason for the difference is that the charter school board included the scores of children who received special accomodations during the testing as a result of special needs or limited English proficiency. As in previous years, the D.C. public school system did not include those students when computing the schools' scores.
