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

The worse of the two measures sets the letter (85%+ to programs is an A; under $15 to raise $100 is an A), averaged over the three most recent filings. Not scored for Carolyn K Tribe Foundation— this filing type doesn't report it, and the rating simply skips it (never counts it against the organization). See the exact thresholds →
