CharityIndex rating
One independent A+ to F grade from four published criteria, each scored separately from IRS filings and combined by weight.
A
AProgram efficiency40% of the rating87% to programs · $10 to raise $100
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. For American Physical Society: 87% to programs · $10 to raise $100 earns a A on this criterion. See the exact thresholds →
AFinancial health25% of the rating37 mo reserves · +14% 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 American Physical Society: 37 mo reserves · +14% margin earns a A on this criterion. See the exact thresholds →
A+Governance25% of the rating6 of 6 checks met
Checks how the organization is run, from its own Form 990: an independent board majority, a board of five or more, conflict-of-interest, whistleblower and document-retention policies, and independently audited financials. The share of disclosed checks that pass sets the letter. For American Physical Society: 6 of 6 checks met earns a A+ on this criterion. See the exact thresholds →
A+Transparency10% of the rating5 of 5 disclosure signals
Counts five disclosure signals: a recent filing, a mission statement, program descriptions, a listed website, and the full expense breakdown. More disclosure, better letter. For American Physical Society: 5 of 5 disclosure signals earns a A+ on this criterion. See the exact thresholds →
