Eight additional states have introduced legislation to fund universal pre-kindergarten programs, bringing the total to 26 states actively pursuing or implementing pre-K for all four-year-olds. The push follows landmark research showing that children who attend quality pre-K programs are 25 percent more likely to graduate high school.

A 20-year longitudinal study published this month tracked 50,000 students and found that pre-K participants earned higher grades, required fewer special education services, and were more likely to attend college than peers who did not attend.

Funding remains the primary challenge, with estimated costs of $8,000 to $12,000 per child annually. Advocates argue the investment pays for itself through reduced spending on remedial education and social services over time.
