The Covid-19 pandemic has vividly illustrated the centrality of frontline workers to the everyday functioning of the American economy and daily life. But while some articles have mentioned the high proportion of immigrant workers in these roles, there has been much less attention paid to the high number of English learners in particular. The proportion of English learners is much higher in certain frontline jobs, such as meatpacking and home health care. Yet acquiring better English skills is one of the most powerful steps a worker can take to improve their earnings and economic prospects. For each bit of English that a worker acquires, their earnings are likely to increase. More English equals more job opportunities, and better-paying ones. And it isn't just the worker's own economic mobility that is improved. Their increased earnings have an immediate effect on the household in which they live, and the broader society of which they are a part. Policies that invest in English language skills can also help to narrow racial equity gaps, helping to remedy some of the policy-driven disparities faced by many English learners. To further this discussion, this report addresses the following questions: (1) What does the current landscape of adult English learning look like?; (2) What can innovative English learning look like?; (3) What can practitioners and skills advocates learn from these innovations?; and (4) How can policymakers best support expansion of effective English learning models?
