C+
—Program efficiency40% of the ratingNo expense breakdown in filings

Not scored for Ellen S Jaffe Foundation— this filing type doesn't report it, and the rating simply skips it (never counts it against the organization). See the exact thresholds →
B+Financial health25% of the rating124 mo reserves · +74% margin
