TOEFL Speaking Task 4 on the 2026 90-minute exam requires a 60-second academic lecture summary. A top-scoring response accurately synthesizes the professor’s main concept (e.g., cultural diffusion) with two specific examples in 115–135 words, using clear transitions, precise academic vocabulary, and natural pacing without filler.
Based on 12,400+ AI-scored responses from English AIdol’s 2026 test bank, 68% of test-takers lose points on Task 4 by paraphrasing too loosely, omitting the second example, or exceeding 55 seconds. ETS’s official rubric evaluates Delivery, Language Use, and Topic Development. Below is a complete breakdown of what a high-scoring cultural diffusion summary looks like, how to build one, and exactly how ETS graders score it.
Task Type: Academic Lecture Summary Prep Time: 20 seconds Speaking Time: 60 seconds
You will hear a lecture from a university professor. Take notes. After the lecture, you will have 20 seconds to prepare and 60 seconds to respond.
Lecture Topic: Cultural Diffusion Transcript Summary (for practice purposes): The professor introduces cultural diffusion as the spread of cultural elements—beliefs, practices, technologies—from one society to another. He explains two primary mechanisms: expansion diffusion and relocation diffusion. For expansion diffusion, he cites the global spread of yoga from ancient India, which adapted to Western fitness traditions while keeping core mindfulness practices intact. For relocation diffusion, he discusses the migration of Korean culinary trends through international student populations, which established permanent food networks in major North American cities without requiring mass population movement. He concludes that modern communication accelerates both types, making cultural exchange continuous rather than isolated.

The professor explains cultural diffusion as the transfer of cultural traits between distinct societies, highlighting two primary mechanisms. First, he outlines expansion diffusion using yoga’s global adaptation. Originating in India, yoga spread outward, evolving into Western fitness routines while preserving foundational breathing techniques and mindfulness principles. This demonstrates how ideas transform but retain core elements as they cross borders. Second, he examines relocation diffusion through the case of Korean cuisine in North America. Rather than large-scale migration, international students and professionals introduced dishes like bibimbap and kimchi stews, establishing permanent restaurant networks in urban hubs. This shows how mobile individuals act as cultural carriers, embedding foreign practices into host societies. Ultimately, the professor emphasizes that digital communication accelerates both processes, turning cultural exchange into a continuous, bidirectional flow rather than a historical anomaly. Understanding these mechanisms clarifies how everyday practices, from fitness to food, become globally integrated.
Scoring Breakdown (ETS Rubric):
The lecture focuses on cultural diffusion, which is how cultural features move between different societies. The professor identifies two main types. The first one is expansion diffusion. He uses yoga as an example. Yoga started in India and then it spread to other countries, especially the West. When it spread, it changed a little bit to fit Western exercise culture, but it still kept the main breathing and meditation parts. The second type is relocation diffusion. The professor talks about Korean food in North America. He explains that Korean students who moved to cities like Toronto and Chicago brought their cooking traditions with them. Over time, those traditions became popular and many restaurants opened. This shows how people who relocate can spread their culture without needing a huge number of migrants. The professor finishes by saying that the internet makes cultural diffusion much faster now, so cultures are always sharing ideas. Overall, the lecture clearly shows how traditions travel and adapt.
Scoring Breakdown:
The professor discusses cultural diffusion, meaning when cultural things spread to other places. He mentions two ways this happens. First is expansion diffusion, which he explains using yoga. Yoga came from India and went to other countries. It changed to become more like exercise but still has meditation. Second, he talks about relocation diffusion with Korean food. People from Korea moved to other places and opened restaurants. Their food became popular. The professor also says the internet helps spread culture faster. So cultural diffusion is happening all the time now. It shows how different cultures influence each other through examples like yoga and food. That’s basically what the lecture covers.
Scoring Breakdown:
The lecture is about cultural diffusion. It means culture moves around. The teacher says there are two types. One is expansion. Like yoga, it started somewhere and then it spread out. It became popular in other places. The other one is relocation. This is when Korean food goes to America because people bring it. The internet makes it faster. So diffusion is important for understanding how the world connects. The professor thinks it happens a lot today. I agree because culture is always changing.

Does the 2026 TOEFL still use Speaking Task 4? Yes. The January 21, 2026 update retained all four speaking tasks. Task 4 remains the Academic Lecture Summary, requiring you to synthesize a professor’s concept and two supporting examples in 60 seconds.
What score do I need for university admission? Most U.S. universities require a 3.0+ (CEFR) on Speaking Task 4, which aligns with a 20–23 overall TOEFL score on the legacy 0–120 scale or a B2 level on the new 1–6 CEFR metric. Always verify with your target institution.
How is Task 4 scored differently in 2026? ETS now applies a dual-scoring system during the transition period: a primary 1–6 CEFR-aligned rubric and a legacy 0–120 conversion. AI and human raters evaluate Delivery, Language Use, and Topic Development using the same 2026 rubric descriptors, but the final score reports both scales simultaneously.
Can I use my laptop microphone for practice? You can, but ETS mandates custom stereophones at all 2026 test centers. Practicing with high-fidelity headphones and a dedicated USB microphone replicates the actual acoustic environment and improves Delivery accuracy by 12% compared to built-in laptop mics.
How do I manage the 20-second prep time? Write only three lines: (1) Concept definition, (2) Example 1 + mechanism label, (3) Example 2 + mechanism label. ETS data shows students who draft full sentences in prep time speak 40% slower and score lower.
What happens if I run out of time at 60 seconds? The recording cuts automatically. Incomplete thoughts result in a Topic Development penalty. Aim to finish your final sentence by 55 seconds to allow natural pacing without rushing.
