Mission Statement

Nassau Humane Society is dedicated to the humane treatment of all animals; to alleviate their suffering and neglect, to support the human-animal bond, and to foster an environment in which people respect all living creatures.

Our solutions will emphasize the mutual benefit of bringing pets and people together. We will provide rescue and control as a lifeline to animals in need and for the necessary protection of our community. We will encourage and provide for pet adoption, animal-assisted therapy, pet care education, outreach spay and neuter program and other welfare efforts, all in support of our comprehensive community service obligation.

CharityAI™ rates charities from 0 to 100 using public filings (IRS Form 990 and the equivalent registries outside the US) together with the information the charity itself provides on DonationX. Ratings are recalculated every quarter, without human bias, and shown as stars.

Four pillars

Financial strength30%

Program expense ratio, fundraising efficiency, operating reserves, liabilities and revenue diversification, compared with similar organizations.

Reliability20%

Standing with the registry, filing history, verification and how complete the profile is.

Effectiveness25%

How much goes to programs and how consistently the organization delivers them.

Impact25%

The outcomes the charity reports on DonationX: people served, cost per service and results.

Stars

★★★★★ 80–100 ★★★★☆ 60–79 ★★★☆☆ 40–59 ★★☆☆☆ 20–39 ★☆☆☆☆ 1–19

A pillar with no data counts as zero. Without impact metrics the score is capped at 59 (three stars): only the charity can supply that data.
The coverage grade (A to D) says how much filing data the score rests on; NONE means there is not enough to rate.
An organization that is not in good standing with its registry (for example a revoked tax exemption) is shown as Not rated.
"Compared with peers" places the charity's key ratios against organizations of the same country, sector and size.
