Scores of Rappahannock's fourth graders on the Science Research Associates (SRA) achievement tests administered last fall have declined slightly from results in 1979-80, reversing a statewide trend of improvement for the past three years.
At the same time, scores of eighth graders here jumped significantly in 1980 while the state average improved only slightly.
At the fourth grade level, Rappahannock students either declined or stayed even with performances of last year’s fourth graders. Compared to SRA results in 1979 as measured against the national average, scores went down in educational ability (49th to 44th percentile), reading (57th to 51st percentile), mathematic concepts (52nd to 46th percentile) and social studies (53rd to 49th percentile). Compared to last year, fourth graders stayed even in language arts (56th percentile), mathematics computation (49th percentile), mathematics total (51st percentile) and science (51st percentile).
The national percentile ranks show the relationships of the scores of Rappahannock students to the scores of a large national sample of students at the same grade level. The 50th percentile (or national norm) is that point above which half the students in the national sample scored and below which half of that same group scored. An average reading score in the 51st percentile means, for example, that the average
