Newly released test scores show D.C. public school students' proficiency in math and reading hasn't increased much since last year.
School officials said Wednesday that 51.1 percent of students were found to be proficient in math during the 2013-2014 school year. That's up 1.6 percentage points from the year before.
In reading, 47.7 percent of students were proficient, up just 0.3 percent from the previous year.
Schools Chancellor Kaya Henderson says she's "somewhat disappointed that we weren't able to demonstrate greater growth.''
This was the last year for D.C.'s own standardized tests. Starting this fall, the school system will move to a new, multi-state test that's aligned with the Common Core academic standards.
As a result, the system won't include test scores in teacher evaluations during the upcoming school year.
