Stanford Study: Elmbrook Student Achievement Among Nation's Best
Stanford University study investigated achievement gap between different school districts across the country

BROOKFIELD — According to a recent study by the Stanford University Center for Education Policy Analysis, published by the New York Times, students in the Elmbrook School District score an average of 2.1 grade levels higher than the national average on reading and math scores.
It’s the third-highest achievement average in the Metro Milwaukee area (second to Whitefish Bay and Mequon-Thiensville) and in one of the top tiers in the country.
The study, which included every school district in the U.S., investigated just how large the achievement gap between students in America's richest and poorest communities truly is.

Overall, the study showed that the yearly income of families was correlated to student performance. The study indicates that the most highly impoverished school districts achieved at levels four grades below children in some of the country's richest school districts.
In the Metro Milwaukee area, for example, while Whitefish Bay students scored 2.5 grades higher than the national average on reading and math scores, and the community median income is $132,000.

In contrast, the average median income in Cudahy is $55,000 and the average scores average out to 0.4 grade levels lower than the national average. Racine’s average median income is comparable at $52,000, but the district is a full grade below the national average on reading and math scores.
Correlation does not necessarily show causation across the country, as some communities with low median incomes have been shown to have high performance in their school districts. Greendale’s is middle of the road when it comes to median income, but has some of the region’s higher-performing students - outperforming students who come from districts whose communities have an average median income of $20-30 thousand higher.
