Accelerating Opportunity (AO) combined integrated career pathways at two-year colleges with team teaching, acceleration strategies, supportive services, and policy changes. It aimed to help low-skilled adults earn occupational credentials, obtain well-paying jobs, and sustain rewarding careers. This final implementation report documents activities and outcomes for AO states and colleges in Illinois, Kansas, Kentucky, and Louisiana. Ingredients for successful implementation included receiving state leadership support, remedying policy barriers, considering college institutional factors, investing in team teaching, utilizing partnerships within and outside the colleges, and providing student supports.
