How to Use This Cross-Section

Pages that intersect a single NTEE category and a single state are the most apples-to-apples comparison NonprofitTruth offers. The donor question they answer is narrow: among the health charities operating from a Maryland office, how does Organization X compare on financial structure to Organization Y? Sort by revenue first to keep scale roughly constant, then sort by Efficiency Score within a tier.

The NonprofitTruth Efficiency Score is a 0–100 composite that summarizes four signals from the Form 990: program-spending ratio (50% of the score), revenue-growth consistency over multiple years (20%), months of fund reserves on the balance sheet (20%), and CEO compensation as a share of revenue (10%). The grade A–F mapping is purely descriptive — it summarizes the financial structure that the 990 reveals, not the social impact, program quality, or outcomes of the work the organization does. Donors evaluating impact should pair these financial signals with program-level evaluations from sources like Charity Navigator, GiveWell, or the organization's own audited reports.

Frequently Asked Questions

How many health nonprofits are based in Maryland?

4 organizations are categorized as Health on the IRS Form 990 and list a Maryland principal office address. Combined annual revenue is $13.2B; average Efficiency Score across the group is 81/100.

Are these all the health charities operating in Maryland?

Not necessarily. The list reflects organizations whose Form 990 lists Maryland as the principal office. National health charities that operate programs in Maryland but headquarter elsewhere appear in their home state’s page instead.

What does the average Efficiency Score of 81/100 represent?

It is the simple average of the NonprofitTruth Efficiency Score across the 4 organizations on this page. The Score weights program-spending ratio (50%), revenue-growth consistency (20%), reserves (20%), and CEO-comp ratio (10%). It is descriptive of financial structure, not of program impact.

Why might two health nonprofits in Maryland score very differently?

Common drivers: a difference in revenue scale (which affects fixed-cost ratios), a capital-campaign year on one side that distorts the program ratio, a reliance on professional fundraisers (counted outside program services on Form 990), or a different mix of program-vs-administrative classification by the organization’s auditor. The 990’s Schedule O narrative usually explains unusual movements.

Where can I see the original Form 990 for these health charities?

Each organization links to a profile that cites the source filing year. From the profile, the original return is one click away on the IRS Tax Exempt Organization Search and on the ProPublica Nonprofit Explorer.
