What finding was revealed by studying two early childhood programs serving low-income children?

The finding that was revealed by studying two early childhood programs serving low-income children is that there were fewer special education placements for enrolled children. This outcome suggests that effective early childhood education can positively impact children's development and learning. Programs that focus on the holistic development of children, particularly those in low-income situations, can strengthen their foundational skills, which in turn helps them succeed academically and socially. This reduced need for special education placements indicates that high-quality early learning experiences can mitigate developmental delays and support children’s readiness for school, leading to better outcomes as they progress in their education.

The other options do not align with the findings related to the effectiveness of early childhood programs; they suggest less favorable or unrelated outcomes. The results emphasize the role of early intervention and quality programming in supporting children's development, which is critical in early childhood education.
