If you've been researching the 11+ exam for specialist language schools, you've probably come across the term "LAT" and felt immediately confused. You're not alone. On parenting forums, the Language Aptitude Test is one of the most asked-about and least understood parts of the grammar school entrance process. Here's what it actually is, what it tests, and what you can realistically do to prepare.
The Language Aptitude Test is an additional component of the 11+ used by specialist language schools — schools that offer an enhanced modern foreign languages curriculum. It's designed to assess a child's potential to learn languages, not their existing knowledge of any particular language.
This is a crucial distinction. A child who speaks three languages at home has no inherent advantage, because the LAT deliberately uses invented or obscure languages that no candidate has seen before. It's testing the underlying cognitive skills that make someone good at learning languages, not how many they already know.
The LAT is most commonly associated with schools that have a designated specialism in languages. Examples include some grammar schools in Kent, Buckinghamshire, and parts of London. Not all grammar schools use it — only those with a specific language focus. If you're unsure whether your target school includes a LAT, check the admissions page on the school's website or call their admissions office directly.
The test typically includes several types of exercise, all based on made-up or unfamiliar language systems:
The LAT is deliberately designed to be preparation-resistant. Because the languages are invented fresh for each exam sitting, you can't memorise vocabulary or grammar rules in advance. Traditional 11+ workbooks barely touch it — Bond and CGP, the two most popular series, have limited or no LAT content.
That said, the underlying skills can be practised. A child who has done lots of pattern-recognition exercises, who is comfortable with the idea of working out rules from examples, and who has been exposed to the format of LAT questions will feel far less intimidated than one seeing them for the first time on exam day.
Here are the approaches that actually help:
The LAT is usually sat alongside the standard 11+ papers (English, Maths, Verbal Reasoning, Non-Verbal Reasoning). It typically lasts 20–30 minutes. Remind your child that nobody is expected to finish every question — the test is designed to differentiate at the top end, so leaving some blanks is completely normal.
The LAT can feel like an unfair wild card, but it actually levels the playing field in an important way. It rewards natural aptitude and quick thinking rather than months of expensive tutoring. A child from any background, with any level of prior language learning, has a genuine shot — and that's rather the point.
If your child enjoys puzzles, picks up on patterns quickly, and finds the idea of invented languages fun rather than frightening, the LAT might turn out to be their strongest section. The best preparation is making sure they've seen the format before, so nothing on exam day comes as a surprise.
