Eighth and ninth graders at Browne, Deal, Jefferson and Kelly Miller junior high schools and Hobson and Hardy middle schools made the highest overall test scores on national comprehensive standardized tests this year.

Students at Banneker, the city's academic high school, plus Wilson and the School Without Walls made the highest scores at the ninth and 11th grade levels.

Meanwhile, students at Anacostia High School in Southeast, who remain at the bottom in terms of test scores, made impressive gains above last year's scores, according to the recently released test results.

Meanwhile, for the second time in as many years, the lowest reading score among third graders was made by pupils at an inner-city school.

Third graders at Cook Elementary School, on P Street NW between North Capitol and First streets, scored a year and six months below the norm. Last year, third graders at Lewis Elementary School, 300 Bryant St. NW, scored about a year below the norm. Third graders at Murch School, in upper Northwest, had the highest scores, which were five years above their grade level.

Overall, the number of third graders scoring at or above their grade level on the standardized reading tests decreased this year.

Last year, of the 121 elementary schools in the city, 107 had third graders who scored at or above the 3.8 norm on the reading portion of the Comprehensive Tests of Basic Skills. This year, there were 93, a decrease of 14. The number of schools with third graders at or above the math norm increased from 105 to 108. The comprehensive tests measure students' skills in reading, language, math and science.

In previous years, elementary pupils showed marked improvement on the tests, which school officials attributed to the installation of a back-to-basics curriculum. The recent test scores reveal a leveling off, some officials said.

This year there were 65 schools with sixth graders scoring at or above the reading norm, an increase of eight. In 1984 there were 57, and the year before that there were 64, indicating inconsistent performance. The same is true for sixth grade math scores. In 1983, there were 90 schools whose sixth graders were at or above the norm. Last year there were 81, and this year there were 88. Ninth graders across the city improved their total scores by four months, but they still scored significantly below their grade level. Ninth graders at Northeast schools scored above their peers in other parts of the city. Eighth graders in Northwest scored higher than their peers and matched the national norm.

D.C. Schools Superintendent Floretta McKenzie stated last year that she wanted all high schools to have 11th grade scores "no lower than one year below the national norm" in reading and mathematics. But this year no high school with low test scores achieved that mark in both areas. Last year, only 11th graders at Banneker and School Without Walls, where scores have traditionally been high, scored above the norm in those areas. This year those two schools and Wilson exceeded the norms.
