Graduation rates among district-run schools, meanwhile, have steadily increased in the last ten years. In 2005, Philadelphia had a district graduation rate of 52%. This number has increased to 65% in 2014, still below the national and state averages. Scores on the state's standardized test, the Pennsylvania System of School Assessment (PSSA) have trended upward from 2005 to 2011 but have decreased since. In 2005, the district-run schools scored an average of 37.4% on math and 35.5% on reading. The city's schools reached its peak scores in 2011 with 59.0% on math and 52.3% on reading. In 2014, the scores dropped significantly to 45.2% on math and 42.0% on reading.
