ESOL teaches English.
It does not get people into work.

What ESOL was designed to do

ESOL — English for Speakers of Other Languages — is one of the most important parts of the adult skills landscape. It gives people the communicative tools to navigate daily life, access services, support their children's education, and participate in their community. When it works well, it is transformative.

It was not designed to get people into skilled employment. This distinction matters enormously, and the confusion between the two goals has cost a significant amount of money and a significant amount of time for the people most in need of both.

The design problem

ESOL curricula are built around communicative competency — the ability to understand and produce spoken and written English in general, everyday contexts. The CEFR framework that underpins most ESOL delivery measures progress in terms of general language ability: can the learner understand simple instructions? Can they write a short message? Can they take part in a basic conversation?

These are meaningful achievements. They are not, by themselves, employment outcomes.

An employer hiring for an HCA role does not ask "can this person understand simple instructions in English?" They assess whether the person can read a care plan, document accurately in a patient record, communicate a handover to a ward nurse, and respond correctly to clinical abbreviations. These are not general English tasks. They are sector-specific language tasks — and ESOL provision, by design, does not teach them.

The waitlist problem compounds the design problem

Even a perfectly designed ESOL programme would struggle to close the employment gap if the wait to access it is six, twelve, or eighteen months. In practice, waits of this length are common across England, and in some areas, significantly longer.

The impact of this wait is not neutral. A qualified professional who arrives in the UK and spends eighteen months waiting for language provision, during which time they are working in an unskilled role, does not arrive at the ESOL classroom in the same state they were in when they needed the provision. Professional skills deteriorate without use. Professional confidence erodes. The sense of professional identity — the belief that one is and will remain a nurse, an engineer, a teacher — weakens.

By the time provision begins, the person is not simply a qualified professional who needs language support. They are a qualified professional who has spent a year and a half having their professional identity slowly dismantled by a system that does not see what they can do.

What the evidence says about what works

The research on vocational language training — English for Specific Purposes, sector-specific ESOL, occupational language programmes — consistently shows better employment outcomes than general ESOL for people who have a clear employment destination.

The most significant factor is not the language content itself but the specificity of the target. When a learner knows that what they are learning maps directly onto the vocabulary of the ward, the site, the classroom, or the office they are trying to enter, engagement is higher, completion rates are higher, and the transition into employment is faster.

This is consistent with self-determination theory: people engage more deeply with learning when they can see a clear and proximate connection between the learning and a goal they care about. General ESOL provides a distal connection at best. Vocational fluency training provides a proximate one.

The role of simultaneous bilingual instruction

One of the least-discussed design problems in ESOL provision is the assumption that all instruction should be delivered in English. This is linguistically defensible — immersion is effective for language acquisition — but practically counterproductive for sector-specific professional vocabulary acquisition.

A nurse learning the English term "medication reconciliation" learns it more quickly, more deeply, and with better long-term retention if she simultaneously sees its equivalent in her home language. The home language provides the cognitive anchor. Without it, she is learning a new word for a concept she already holds in a different language — a significantly harder cognitive task than connecting a new English word to an existing native-language concept.

Simultaneous bilingual instruction — teaching sector-specific English alongside the equivalent native-language terms — is not a concession to learners who are not yet "ready" for English-only instruction. It is the most efficient method of professional vocabulary acquisition available, and its absence from most ESOL provision is a significant missed opportunity.
