Scale scores

Academic Performance Calculation

In California and many states, Academic Performance is defined as "Difference From Standard" (DFS), where "standard" is zero on a scale of -300 to +200.

The "Met Min" number below converts to a DFS of zero, which is the minimum number to meet the standard.

But DFS is not provided in the downloadable research files. Instead a Mean Scale Score is provided.

Simply subtract the "Met Min" number for the grade and test type in the table below from the Mean Scale Score to get the DFS.
