Children International delivers health care, education support and life-skills programmes to children living in poverty through local community centres, pairing individual sponsors with a specific child for $39 a month. The organisation states it holds a 4-star Charity Navigator rating and a GuideStar/Candid Platinum Seal of Transparency.
A fairly standard child-sponsorship model, comparable to Plan International or Compassion International elsewhere on this site. We could not independently re-confirm the 4-star Charity Navigator rating this organisation cites on its own site (two secondary sources repeat it, but we didn't load charitynavigator.org directly this round) — worth a quick check yourself before treating it as current.
