100 Must-Know PTE Academic Vocabulary Words — Organised by Task Type With Study Tips
The PTE Academic exam is a computer-based English proficiency test accepted by universities, employers, and governments worldwide — including Australian and New Zealand immigration. Unlike IELTS, PTE is scored entirely by AI, which means vocabulary precision matters even more. The algorithm rewards you for using accurate, contextually appropriate words and penalises vague or repetitive language. This guide gives you 100 essential PTE vocabulary words that appear across all four communicative skills: Speaking, Writing, Reading, and Listening.
Every word on this list was selected based on frequency analysis of PTE practice materials, the Academic Word List (AWL), and real test-taker reports. These are not random GRE-level words. They are practical, high-scoring terms that PTE's algorithm specifically looks for when evaluating your vocabulary range, collocations, and academic register.
We have organised the full list by PTE task type so you can focus your study on the sections that matter most to your target score. At the end, you will find a step-by-step study plan for learning all 100 words using spaced repetition flashcards.
PTE Academic uses an integrated scoring system. Your vocabulary does not get a separate band score like IELTS — instead, it feeds into multiple enabling skills simultaneously. When you use precise academic vocabulary in the Summarise Written Text task, you boost your Writing score, your Reading score, and your vocabulary score all at once. This integrated approach means that improving your vocabulary has a multiplier effect on your overall PTE score.

Speaking
PTE's AI scoring engine evaluates your oral fluency and vocabulary range. Using precise, topic-appropriate words in Describe Image, Re-tell Lecture, and Answer Short Question directly raises your score.

Writing
Summarise Written Text and Write Essay both reward academic vocabulary, accurate collocations, and varied word choice. Repetitive language signals a lower proficiency level to the algorithm.

Reading
Fill in the Blanks and Re-order Paragraphs require recognising academic vocabulary in context. Knowing collocations and word forms is essential for choosing the correct answer.

Listening
Summarise Spoken Text and Fill in the Blanks (Listening) test whether you can recognise academic words spoken at natural speed. Familiarity with these words makes real-time comprehension possible.
PTE test-takers who focus on targeted vocabulary study — especially with spaced repetition — consistently report score improvements of 10 to 20 points. Because PTE is AI-scored, there is no examiner subjectivity. The algorithm counts every precise word choice, every correct collocation, and every accurate synonym. Your vocabulary literally becomes your score.
If you have studied for IELTS before, understanding how PTE scores vocabulary differently will help you adjust your preparation. Here is a quick comparison:

The key takeaway: PTE rewards precise vocabulary more consistently than IELTS because there is no human variability. Every correct collocation counts. Every synonym choice is evaluated algorithmically. This makes flashcard-based vocabulary study especially effective for PTE — you can train the exact words and word forms the algorithm looks for.
We have grouped these words into ten topic clusters that appear repeatedly across PTE Speaking, Writing, Reading, and Listening tasks. Each word includes a definition, a PTE-style example sentence, and a note on which task types it is most useful for.

Learning 100 words might sound ambitious, but with spaced repetition flashcards it is entirely manageable. Here is a structured plan that builds your vocabulary progressively without overwhelming you:
W1
Week 1 — Education, Environment, Technology (30 words)
Learn 5 new words per day from topics 1–3. Review all previous words daily using flashcards. Focus on definitions and example sentences.
W2
Week 2 — Health, Economics, Society (27 words)
Add 4–5 new words per day from topics 4–6. Continue reviewing Week 1 words — spaced repetition will space these reviews out automatically.
W3
Week 3 — Government, Media, Connectors (26 words)
Complete topics 7–9. Pay special attention to academic connectors — practise using them in sentences you write yourself.
W4
Week 4 — General Academic + Full Review (17 new + review)
Learn the final topic. By now, spaced repetition has your older words on longer intervals. Daily reviews should take 15–20 minutes.
W5
Week 5 — Active Production Practice
Shift from recognition to production. Write PTE-style essay paragraphs using 5–10 target words per paragraph. Practise Describe Image using topic vocabulary aloud.
W6
Week 6 — Exam Simulation + Final Review
Take a full PTE practice test. Continue daily flashcard reviews — they should now be fast. Focus on any words you still find difficult.
1 Learn collocations, not just definitions
PTE's Fill in the Blanks tasks test whether you know which words naturally go together. "Conduct research" is correct; "do a research" is not. Flashcards that include example sentences train your ear for natural collocations.
2 Know all word forms
PTE often tests word forms: "sustain" (verb), "sustainable" (adjective), "sustainability" (noun), "sustainably" (adverb). When you learn a new word, learn its family. This is especially important for Reading Fill in the Blanks.
3 Practise pronunciation for speaking tasks
PTE's AI scores your pronunciation. Mispronouncing "hypothesis" or "bureaucracy" costs you points even if you use the word correctly in context. Use penguen.io's AI pronunciation feature to hear and practise each word.
4 Use academic connectors in Write Essay
PTE's Write Essay task rewards coherent structure. Using connectors like "nevertheless", "furthermore", and "consequently" signals advanced proficiency to the algorithm and directly improves your writing score.
5 Avoid word repetition in summaries
In Summarise Written Text and Summarise Spoken Text, PTE penalises repetitive vocabulary. Having a bank of synonyms — "increase/rise/surge", "decrease/decline/drop" — lets you paraphrase effectively and score higher.
help "Is PTE vocabulary different from IELTS vocabulary?"
There is significant overlap — both tests draw from the Academic Word List and cover similar topics. However, PTE places more emphasis on exact collocations and word forms because it is AI-scored. The algorithm counts precise word usage more strictly than a human examiner might.
help "What PTE score do I need for Australian immigration?"
For most skilled visa subclasses, you need at least PTE 50 (equivalent to IELTS 6). For higher points on the points test, PTE 65 (IELTS 7) or PTE 79 (IELTS 8) is required. These 100 words target the PTE 65–79 range where academic vocabulary makes the biggest difference.
help "How long should I study before taking PTE?"
Most test-takers with intermediate English (B1–B2) need 6 to 12 weeks of focused preparation. Following the 6-week vocabulary study plan above while also practising PTE task types gives you a strong foundation. Consistency matters more than volume — 20 minutes of daily flashcard review beats weekend cramming sessions.
help "Can I use these words for TOEFL and Cambridge exams too?"
Absolutely. These 100 words are drawn from the Academic Word List, which is relevant to all major English proficiency exams. While the study tips in this guide are PTE-specific, the vocabulary itself transfers directly to IELTS, TOEFL, and Cambridge Advanced.
The 100 words in this guide represent the highest-value academic vocabulary for PTE success. They span the topics that appear most frequently in Speaking, Writing, Reading, and Listening tasks. They include the academic connectors that signal advanced proficiency to PTE's AI scoring engine. And they are exactly the kind of words that separate a PTE 50 from a PTE 79.
But knowing which words to learn is only the beginning. How you study them determines whether they stick under exam pressure. Spaced repetition flashcards — the method backed by decades of cognitive science — give you the most efficient path from seeing a word for the first time to using it confidently in a timed PTE task.

PTE is scored by an algorithm. An algorithm rewards precision. Precision comes from knowing exactly the right word — and that comes from deliberate, spaced practice.
