What EAL acceleration actually means
EAL acceleration is not the same thing as EAL support. Support is the steady, low-intensity scaffolding that a non-native speaker receives over years. Acceleration is the time-bound, intensive intervention that gets a child from beginner or low intermediate level to functional academic English within months rather than years. The two have different staffing, different timetables, and different success criteria. Schools that conflate the two in their prospectus copy are usually offering support but charging in language that implies acceleration.
The clinical model behind acceleration is well established. A child with no functional English needs roughly 600 to 800 hours of intensive English instruction to reach academic fluency. Spread across a school year of 1,200 contact hours, that is half the timetable in the first year. A school that offers four hours a week of EAL on top of a full mainstream timetable is not running an acceleration programme. It is running a support programme and hoping for the best.
For the broader picture of EAL provision across the year groups, see our piece on EAL programmes at international schools.
The honest timeline from beginner to mainstream
The literature on second language acquisition is mature and the numbers are reasonably settled. A child with no prior English at the start of an intensive programme can be expected to reach functional conversational English in 6 to 9 months and academic English to the level required for mainstream subject teaching in 18 to 24 months. The variation depends on age, first language proximity to English, prior literacy, motivation and the family's home language environment. A native German speaker accelerates faster than a native Mandarin speaker because the linguistic distance is smaller. A child arriving with strong literacy in any first language outperforms a child whose first language literacy is weak.
The implication for parents is that any school promising mainstream readiness in a single term is overpromising. Schools that talk in terms of one to two years are being honest. Schools that talk in terms of three months are either using a different definition of mainstream readiness or relying on the child's hard work and family support to do the rest. The honest version of acceleration is intensive provision for one to two years, after which the child still benefits from targeted support for academic English, particularly in writing and in the language-heavy humanities subjects.

The three delivery models you will see
International schools deliver EAL acceleration through one of three models, occasionally a hybrid.
The intensive immersion model. The new arrival joins a parallel EAL class for part of the school week, typically replacing English literature and humanities, while attending mainstream maths, science and arts with EAL in-class support. The intensive immersion model produces the fastest acceleration but is expensive to staff. It is most common in schools with EAL intakes above 15 per cent of cohort.
The pull-out support model. The new arrival follows a mostly mainstream timetable with three to five hours a week of withdrawn EAL teaching, often delivered by a peripatetic specialist. This is the most common model across the international school market. It serves intermediate-level children well; it serves complete beginners poorly because the contact hours are insufficient for acceleration.
The push-in support model. An EAL specialist co-teaches with the mainstream teacher in language-heavy lessons. Push-in produces good social and curricular integration but slow language acceleration. It works for advanced EAL children consolidating academic English; it works poorly for beginners.
The strongest schools operate a hybrid: beginners start in intensive immersion for a term, move to pull-out support, then push-in consolidation, then exit the register. Transitions are data-led and the parents see the assessment that triggered them.
How schools assess EAL needs
Reliable assessment is the foundation of credible EAL provision. The two frameworks in widest international use are the WIDA system, from the United States, and the EAL Assessment Framework derived from the UK National Curriculum. Both calibrate to a five or six stage scale running from new to English to fully fluent. The framework matters less than the rigour with which the school uses it.
A credible programme assesses each new arrival on arrival, again at the end of each term, and against externally validated benchmarks annually. The assessment covers four domains: listening, speaking, reading and writing. Children should exit support when they demonstrate mainstream-level performance across all four for two consecutive assessment points. Schools that drift on exit criteria leave children in EAL longer than necessary; schools that exit too aggressively leave children stranded in mainstream classes without the language for academic writing.
Integration with the mainstream curriculum
EAL acceleration must integrate with the rest of the curriculum or it produces children who speak good English but cannot follow a lesson. The two integration questions are first, how the EAL specialist and the subject teacher collaborate, and second, how the curriculum's language demands are scaffolded for the EAL child.
The strongest schools we observe build the EAL specialist into curriculum planning. The EAL teacher reads the next term's schemes of work alongside the subject teacher, identifies the language demands of each unit, and pre-teaches the relevant vocabulary and grammar to the EAL children before the unit begins. This is invisible to parents but it determines whether the EAL children walk into a science lesson on cells with the vocabulary already in hand or whether they spend the lesson catching up to the conversation.
Curriculum scaffolding is also visible in the textbooks the school selects. The best international schools choose subject textbooks with strong glossary and visual support, suitable for an EAL cohort. The weaker schools select textbooks written for native speakers and then make the EAL children manage with a dictionary.
For the related question of how curriculum choice shapes EAL provision, see our pieces on the IB curriculum and the British curriculum. IB schools tend to handle EAL acceleration well because the diploma's two-language requirement forces the school to think systematically about language.
Questions to ask on a school tour
Five questions read the depth of provision. First, how many EAL specialists the school employs and what proportion of the cohort is on the EAL register. The ratio matters. A school with one EAL teacher for 200 EAL children is rationing.
Second, what proportion of the EAL cohort exits the register each year, on what assessment criteria. A school that exits 30 per cent annually with documented assessment is moving children through the programme. A school whose exit rate is 5 per cent is keeping children in EAL longer than necessary.
Third, what the school does for a complete beginner arriving mid-year. The answer should include a structured first term, intensive timetabled provision, and a named EAL contact for the family. A school whose answer is we welcome new arrivals at any time has not thought about the question.
Fourth, how the EAL provision integrates with mainstream subject teaching. Specific examples of pre-teaching, co-planning or scaffolded materials indicate real integration. Generic language about support indicates aspiration without delivery.
Fifth, how the EAL provision integrates with SEN and gifted provision. EAL children can also be SEN children, or twice exceptional. A school that names this connection and describes how it handles overlap is running a sophisticated programme. Our pieces on SEN at international schools and twice exceptional learners cover this overlap.
Exit criteria and ongoing support
Exiting the EAL register is not the same as reaching native-speaker English. The strongest schools maintain monitoring of former EAL children for two years after exit, with a light-touch annual review and ready access to the EAL specialist if needed. This catches the regression that can happen when a child encounters a more language-demanding curriculum in upper secondary, particularly in IB Higher Level subjects or A Level English Literature.
The exit criteria themselves should be transparent. Children should exit when they have demonstrated mainstream-level performance across listening, speaking, reading and writing for two consecutive assessment points. The school should publish this benchmark and apply it consistently. Children who exit prematurely return to the register, which is not a failure but a recalibration.
For the cost dimension of EAL provision, our fees database includes notes on the EAL surcharges some schools apply for intensive provision in the first year. The surcharges are usually modest compared with the tuition fee but worth understanding before enrolment.
