Wilder Research, in conjunction with the Invest Early leadership team and staff, is conducting a longitudinal and cost-benefit evaluation of the program. Annual reports document the implementation and assessment of Invest Early and outcomes for the service system, families, and children. Invest Early is effective in preparing low-income students with multiple risk factors for school success when delivered in sufficient quantity. Highlights of this year six summary include: (1) Home learning environments, which are associated with higher school readiness scores, improve significantly for Invest Early families during their participation; (2) Kindergarten entry results show that Invest Early closed the proficiency gap this year relative to higher-income students and exceeded the low-income comparison group by nearly 1.5 to 1 (53% vs. 37% proficient, where proficiency is defined as achieving 75% of the total points); and (3) Based on third grade MCA-II reading and math tests in 2010-11, Invest Early children have better outcomes than a comparison group of children from low-income families without Invest Early, Head Start, or School Readiness program experience.
