These graphs summarize the reading and math achievement of the 130 students that attended the David Douglas Arthur Academy Charter School for the full year of 2007-08. The Stanford Achievement Test was given at the beginning and the end of the year. The black bar indicates what the national norms are. They indicate the percent of students expected to score in each range based on national averages. The percent of students actually scoring within the five levels of achievement are compared from fall (gray) to spring (white).

Because of high return rates, the percent of students scoring in Low, Below-average an Average ranges are below national norms, and the percent of students scoring in the higher ranges are more.

In the Low and Below-average ranges, the percent of students decreased even more from the beginning of the year (gray) to the end (white) in both reading and math. In the Average and higher ranges, the percent of students dramatically increased from the beginning of the year (gray) to the end (white) in both reading and math, especially in the highest range.

In the lowest range in reading, like all the ranges, 20% of the students are expected to score. In the fall, 15% actually scored in this range, and in the spring, only 2% scored in this range. In the lowest range in math, a similar pattern is seen.

In the below-average range in reading, 12% of the students scored in the fall compared to the 20% expected. In the spring, only 7% scored in this range. In math, the same patterned again can be observed in this range.

The opposite trend begins to happen in the average and higher ranges. The number scoring in these ranges increases, especially in the highest range.
