2. Targeted "urban" students were NOT "fastest improving"

Tables 3-6 show that Black, Hispanic and Disadvantaged DCPS students were "fastest improving" of the 11 urban districts only in grade 4 math; in grade 8 reading, all three fell below their group's 2007 averages.

4. Black, Hispanic and Disadvantaged students' rates of improvement were two to three times faster in the nine years immediately before 2007 than in the eight years from 2007 to 2015

Tables 9-12 compare 1998/2000 to 2007 NAEP score changes to changes from 2007 to 2015. Table 13 combines the four test changes (Tables 9-12) into combined pre- and post-2007 scores.

5. Four Charts with Inaccurate Information from the DCPS website

From the DCPS website: http://dcps.dc.gov/node/1013812

Four charts: The numbers in red are erroneous. The numbers in blue are the correct numbers from the NAEP website.

"DCPS at a Glance: Performance

"National Assessment of Educational Progress (NAEP) Trial Urban District Assessment (TUDA)

"The NAEP TUDA allows comparisons of student performance across urban school districts in large cities (i.e. cities with populations of 250,000 or more). DCPS continues to be the fastest improving urban school district in the country according to data from the 2015 Trial Urban District Assessment (TUDA).

"The graphs below show the average scores of DCPS students on each NAEP TUDA from 2007 – 2015."

198 should be 197 237 should be 241

Thus: +16 should be +17 Thus: +8 should be +4

See: Urban district scale scores for all years, 2002 - 2015:

http://nces.ed.gov/nationsreportcard/districts/ (click DCPS)

244 should be 248

Thus: +14 should be +10
