Start by identifying reputable foundations through charity watchdog websites. These online directories evaluate and provide in-depth information about nonprofit organizations, including their accountability, transparency, and effectiveness in achieving their mission. These directories offer excellent search tools, allowing you to filter foundations by cause, location, and other criteria. They also provide insights into each organization’s mission, goals, and history. Each website has different rating metrics, so it’s worth learning how to evaluate an organization's management and financial health yourself.
