The Oxford 3000™ from the Oxford Advanced Learner's Dictionary

The Oxford Text Checker

The keywords of the Oxford 3000™ have been carefully selected by a group of language experts and experienced teachers as the words which should receive priority in vocabulary study because of their importance and usefulness.

To find out which words in a text are part of the Oxford 3000, type or paste it into the box, then click ‘submit’. The words which are not part of the Oxford 3000 will be highlighted in red. The Text Checker will also tell you what percentage of the words in your text are part of the Oxford 3000. You can use this information to judge the difficulty of a text. In general, the more words highlighted in red, the more difficult the text.

In a typical lower intermediate text close to 100% of the words will be Oxford 3000 keywords.
In a typical upper intermediate text 90-95% of the words will be Oxford 3000 keywords.
In a typical advanced text 75-90% of the words will be Oxford 3000 keywords.

The Text Checker will automatically ignore any numbers (in the form ‘25’ or ‘twenty-five’) or symbols. If there are any proper names in your text, such as Oxford or Smith, you can enter them in the ‘ignore’ box. This will make sure that the Text Checker does not mistake them for difficult words and highlight them in red.

The Text Checker will also check your text to see if there are any words from the specialist lists (Arts, Science and Business and finance). These words will be highlighted in blue.
