These tables show pupils' median percentile scores on the TerraNova, a national standardized test of basic skills. The test was given to first- through eighth-graders this spring. A score of 62 means the average pupil in a school scored better than 61 percent of pupils nationwide. Overall, Baltimore pupils in most grades improved their reading scores, and all grades improved in math. For the fifth year in a row, pupils in the city school system showed overall improvement.
