TOEFL Academic Vocabulary: Science & Research

The TOEFL iBT tests your ability to understand academic content in English. A large part of this content, especially in the Reading and Listening passages, comes from scientific disciplines such as biology, astronomy, geology, or environmental sciences. It's not a separate vocabulary test, but your vocabulary is assessed implicitly and explicitly within these sections. A good understanding of technical vocabulary allows you to grasp texts and lectures faster, comprehend complex relationships, and answer the related questions correctly.

Your vocabulary is primarily tested in two ways:

1. Explicit Vocabulary Questions (Reading Section): These are the most common vocabulary tasks. A word or short phrase in the reading text is highlighted. You then need to choose the word from four answer options that has the same meaning in that specific context. Understanding the context is crucial here, as many words can have different nuances depending on the sentence.

2. Implicit Understanding (Reading & Listening Section): The majority of questions test your vocabulary indirectly. To understand the main idea, important details, or the conclusion of a passage or lecture, you need to know the meaning of the academic terms used. Without this knowledge, it will be difficult to follow the content and answer the questions correctly.

There is no separate score for vocabulary knowledge on the TOEFL iBT. Your ability to understand and apply academic vocabulary directly contributes to the assessment of the Reading and Listening sections (each on a scale of 0-30 points).

A strong performance on vocabulary questions in the Reading section directly contributes to your score. More importantly, however, a comprehensive vocabulary forms the basis for understanding all texts and lectures, thus significantly influencing your overall performance in both sections. Preparaio helps you train exactly this vocabulary.
