Wisconsin has 16 nonprofits in the IRS Form 990 dataset ranked here by efficiency score. The NonprofitTruth nonprofit efficiency rubric combines financial health / operating reserves (40%), revenue-growth consistency (35%), and officer compensation relative to revenue (25%) into a 0-100 composite.
Reading the ranking: top of the list typically combines healthy operating reserves (the highest-weighted factor) with stable multi-year revenue and reasonable officer compensation. Large hospital and university systems often appear near the top in any state — their scale gives them deep balance sheets and steady revenue. Each nonprofit links to its full Form 990 profile. For donors trying to choose between organizations, the efficiency grade is a useful triage — but the underlying reserve position, the multi-year revenue trend, and the officer-comp ratio matter more than the composite letter on any individual decision.
