Advice for interpreting vocabulary coverage
Vocabulary coverage is one indicator of text suitability, not a complete judgment of comprehensibility. Sentence structure, background knowledge, idioms, task demands, and instructional support also matter.
The Professional Vocabulary bands contain the 575 words shared by the TOEIC Service List and Business Service List, ordered into five bands of 115 words.
- 95–100%: most vocabulary is covered.
- 90–94.9%: some vocabulary support may be helpful.
- Below 90%: consider adaptation or substantial support.
