Test Ninjas Research · Updated October 1, 2026
The TOEFL draws its texts from two worlds: everyday campus life — notices, emails, conversations about deadlines and lost files — and academic study, from ecology to economics. This list follows the same split. The easy tier covers campus life, the medium tier the general vocabulary of academic subjects, and the hard tier the precise and specialist words that make advanced passages dense.
How the list is organized Tier Words Themes Examples Easy 400 10 Campus places and movement; Schedule and campus services; Classroom work… Medium 400 10 Argument and interpretation; Research and data; Cause, process, and change… Hard 400 10 Advanced reasoning and argument; Advanced research and measurement; Complex processes and systems…
This is an original Test Ninjas study list, not an ETS word list, and the tiers are our own study levels. Each definition gives one useful sense; many words have others.
Medium words General academic vocabulary: the words for argument, research, processes and the main subject areas of university study. Recognizing these quickly is what keeps you reading and listening at speed through academic passages and talks.

Open the flashcards → How to study a vocabulary list Pick one theme at a time. Words that belong together are easier to remember together. For each unfamiliar word, read the definition, say the word aloud and write one sentence about your own study life. Learn related forms together — analyze, analysis, analytical — without counting each as a new word. The word formation guide shows the patterns. Notice which words go together, such as conduct an experiment. See TOEFL collocations . Test yourself after one day, a few days and a couple of weeks. The quiz on each theme page and the flashcards are built for this.

This is an original Test Ninjas study list, chosen to cover the campus and academic situations the published task descriptions describe. The definitions were written for this list.
How many words do I need for the TOEFL? + There is no fixed number, and no list can cover every word you might meet. This list is a focused starting set of 1,200 high-value words. Broad reading and listening, plus the ability to guess meaning from context, do the rest.
What do the easy, medium and hard tiers mean? + They are study levels within this list, not ETS or CEFR levels. Easy words are everyday campus language, medium words are general academic vocabulary, and hard words are precise or subject-specific terms that are mostly worth recognizing.
Which words should I study first? + Start with any easy words you do not know well enough to use, then work through medium themes that match subjects you find hard to follow. Leave the hard tier until the first two feel comfortable.
Does the TOEFL test vocabulary directly? + Yes and no. Complete the Words asks you to restore partly missing words in a passage, so spelling and word form matter. Elsewhere, vocabulary is tested indirectly: you need it to understand what you read and hear, and to express ideas precisely.
