TOEFL Speaking Task 3 requires you to read a campus notice, listen to a related conversation, and summarize both within 60 seconds. When the passage introduces an economic concept like opportunity cost, your response must explicitly name the trade-off, quantify what is sacrificed, and connect it to the student’s final choice. ETS’s updated 2026 rubric evaluates Delivery, Language Use, and Topic Development. Below are four model responses at CEFR-aligned score levels 3.0, 4.0, 5.0, and 6.0, followed by scoring breakdowns, vocabulary, and common errors.

Sample Prompt (Paraphrased from ETS 2026 Format)

Reading (Campus Bulletin Board, 45 seconds): The university’s Career Center will replace traditional drop-in advising with mandatory semester-long mentorship pairings. Students must commit to at least six sessions per term. The administration states that structured guidance yields higher internship placement rates and reduces scheduling errors during registration.

Listening (Student Conversation, 60 seconds): Two students discuss the change. The first student supports it, citing better internship outcomes. The second student, Mark, disagrees. He explains that committing to six sessions means sacrificing 12 hours per semester that could be used for part-time work in his major’s department. He notes that while the mentorship might help with resume building, the lost income and practical lab experience represent a higher opportunity cost than the advising benefit provides.

Task Question: Explain the proposed change and summarize the student’s opinion, specifically referencing the economic concept discussed.

Model Responses by Score Level

Score 5.0 / 27-29 Range (High Advanced)

The Career Center is replacing flexible drop-in advising with mandatory semester mentorships requiring six mandatory meetings. The university claims this structured approach improves internship placement and prevents registration mistakes. However, the male student opposes this policy because he calculates the opportunity cost as too high. He argues that dedicating twelve hours per term to mandatory meetings means giving up twelve hours of paid part-time work in his department’s lab. While he acknowledges that mentorship could strengthen his resume, he emphasizes that the financial loss and hands-on research experience he would sacrifice outweigh the administrative benefits of structured advising. Therefore, he concludes that the program ignores the true economic trade-off students face, and he prefers keeping the flexible drop-in system.

Score 6.0 / 29-30 Range (Advanced/Proficient)

The university’s Career Center is eliminating drop-in advising in favor of mandatory semester mentorships that require exactly six sessions per term. Administrators argue this shift boosts internship placement rates and reduces scheduling conflicts. In the conversation, Mark strongly disagrees with this policy by applying the concept of opportunity cost. He points out that committing to six advising sessions consumes twelve hours each semester—time he would otherwise spend working part-time in his department’s research lab. He acknowledges that mentorship might offer some resume value, but he stresses that the foregone wages and practical experimental training represent a significantly higher value than the administrative guidance provides. Consequently, Mark concludes that the mandatory structure forces students to sacrifice tangible career development for a less impactful service, making the policy economically inefficient.

Score 4.0 / 22-24 Range (Intermediate-High)

The notice says the Career Center will change from walk-in help to required mentorship. Students must attend six meetings each semester. The school says this will help students find internships better and stop registration errors. The male student says he does not like this change. He talks about opportunity cost. He says if he goes to six meetings, that is twelve hours. He could use those twelve hours to work in the lab and make money. He thinks the mentorship is okay for resumes, but losing money and lab practice is worse. So he thinks the school should keep the old system because the cost is too high for students who want real experience.

Score 3.0 / 18-21 Range (Intermediate)

The reading talks about Career Center changing. Now students have to do mentorship with six meetings. The university thinks it is good for internships and registration. The student in the listening says no. He says opportunity cost is important. If he spends time in meetings, he cannot work in lab. He will lose money and experience. He thinks mentorship helps a little but not enough. The cost is too big. He wants the old system back because students can manage their own time better. The school should not force meetings.

Scoring Breakdowns by Rubric Area

| Score Level | Delivery (Clarity, Pace, Intonation) | Language Use (Grammar, Lexical Range) | Topic Development (Synthesis, Accuracy, Completeness) | |---|---|---|---| | 3.0 | Noticeable pauses, flat intonation, minor mispronunciations hinder flow. | Basic sentence structures, repetitive vocabulary, 3-4 grammatical errors that don’t obscure meaning. | Covers main points but lacks depth; opportunity cost mentioned but not explained; synthesis is superficial. | | 4.0 | Generally clear pacing, occasional hesitations, mostly natural stress patterns. | Mix of simple/complex sentences, adequate but imprecise terminology, 2-3 minor errors. | Identifies both sources, explains trade-off loosely, connects to student’s stance but misses nuanced economic framing. | | 5.0 | Smooth pacing, clear articulation, appropriate emphasis on key terms. | Varied syntax, strong academic vocabulary, rare errors that don’t distract. | Fully integrates reading/listening, explicitly defines opportunity cost, links sacrifice to decision, minor omissions only. | | 6.0 | Effortless delivery, native-like rhythm, strategic pausing for emphasis. | Precise, discipline-specific lexicon, complex but accurate structures, near-zero errors. | Seamless synthesis, quantifies trade-offs, evaluates economic efficiency, addresses counterpoint, fully meets all task demands. |

5 Common Mistakes on Opportunity Cost Task 3 Prompts

1. Defining the concept without applying it – Students define opportunity cost but don’t link it to the student’s specific hours, income, or lab time.
2. Over-summarizing the reading – Spending 20+ seconds on bullet points leaves no time for the listening analysis.
3. Vague quantification – Saying “a lot of time” instead of “twelve hours per semester” weakens Topic Development scoring.
4. Ignoring the counterpoint – Failing to note that the student acknowledges some resume benefit reduces synthesis depth.
5. Misaligned pacing – Rushing through the conclusion or trailing off at 45 seconds cuts Delivery scores.

Quick Action Steps

1. Read the notice in 15 seconds, underline the policy and claimed benefit.
2. Listen for the student’s explicit trade-off and any numerical details.
3. Draft a 4-sentence structure: Policy + Claim → Student’s Stance → Opportunity Cost Quantified → Conclusion.
4. Practice with a 60-second timer; aim for 130-145 words at natural speaking pace.
5. Record, transcribe, and check for missing economic linkages before scoring.
