Academic Word List: Which 570 Words Matter Most for Band 7

The Academic Word List (AWL) is a set of 570 word families compiled by Averil Coxhead in 2000 from a 3.5-million-word corpus of academic texts. These are the words that recur across academic writing in every subject — analyse, significant, consequence, derive, framework — which makes them the highest-value vocabulary to learn for IELTS Reading and Writing, where academic register is exactly what's being tested.

Why the AWL is high-leverage for IELTS

The AWL accounts for roughly 10% of the words in typical academic texts, while making up only a small fraction of the vocabulary you'd meet in everyday English. That density is the point: learning 570 families gives you disproportionate coverage of the language used in IELTS Reading passages and the register expected in Writing. Master them and academic passages stop feeling dense, because you recognise the connective scholarly vocabulary holding them together.

How the list is organised: sublists by frequency

Coxhead split the AWL into ten sublists, ordered by frequency. Sublist 1 contains the most frequent families (analyse, approach, area, assess, concept), Sublist 10 the least. This ordering is a built-in study plan: start at Sublist 1, where each word gives you the most coverage per unit of effort, and work outward. Don't try to learn all 570 at once — frequency order means the early sublists repay learning fastest.

Word families, not single words

The AWL counts families, not individual words. "Analyse" brings "analysis, analytical, analyst, analysed". For IELTS this matters because Writing rewards using the right form: turning a verb into its noun (analyse → analysis) or adjective (significant → significance) is part of Lexical Resource and Grammatical Range. Learn each headword together with the forms you'd actually use in an essay.

How to reach Band 7 with the AWL

Band 7 Lexical Resource asks for a sufficient range, some less common vocabulary, and accurate collocation. The AWL supplies the range; the key is to learn each word with a natural example so you absorb its collocations (conduct research, pose a threat, address inequality), not just its definition. Recognition isn't enough — you need to produce these words accurately under time pressure, which is precisely what spaced-repetition review with example sentences builds.
