Preliminary

Why doesn't this school have a score?

We don't have enough verified data to rate this school fairly. Private schools in CA aren't required to report standardized test scores to the state, which limits the data available for our rating model.

Our rating model requires at least 2 of 4 data components (academics, student progress, college readiness, and resources) to generate a meaningful score. Schools below this threshold receive a Limited Profile to avoid misleading ratings.
