One independent A+ to F grade from four published criteria, each scored separately from IRS filings and combined by weight.
B
—Program efficiency40% of the ratingNo expense breakdown in filings
Measures how much of every dollar spent actually reaches programs, plus what it costs to raise $100 of donations. 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 The Connecticut Audubon Society Incorporated— 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 rating145 mo reserves · +30% margin
Measures whether the organization is built to last: how many months its reserves would cover expenses (3+ months earns an A-range score, but hoarding 5+ years of budget is capped) and whether it runs a surplus or a deficit. For The Connecticut Audubon Society Incorporated: 145 mo reserves · +30% margin earns a B+ on this criterion. See the exact thresholds →
