Operation Outreach-USA is tackling the almost epidemic problem of improving reading proficiency among Kindergarten through fourth grade students in low income and poor performing schools. OO-USA is currently being used by hundreds of elementary schools across the country, providing books for children to keep and instructional materials for teachers and parents. Additionally, the majority of the books used in the program are published by Operation Outreach-USA Press. This allows for the titles to be current, culturally diverse and relevant to the populations served by the program. Publishing its own books allows OO-USA to maintain lower costs and avoid costly publisher fees.
