The Philadelphia Business Journal reported that Wissahickon School District and Upper Dublin School District rank 15th and 16th, respectively, out of 492 Pennsylvania schools for students’ standardized test scores.
To calculate the rankings, the news outlet used all available Pennsylvania System of School Assessment scores for math, English and science and Keystones for literature, algebra and biology from the past three years, minus the 2021 and 2022 Keystones.
From their article:
The rankings are based on a district’s percentage of students placing in the top two standardized test categories. That score is then compared to its departure from the average for the set. This is also known as a standard score, or “z-score,” a measurement of the number of standard deviations a district scored above or below the mean for the data set being examined. The z-scores for each component in a grade are summed to create a grade score. The sum of all the grade scores makes up a district’s overall score.
