Written Expression
The TEF includes a structured task such as writing a news-style article, which can be easier if you know the format. The TCF uses more traditional writing tasks, but strict time limits may increase pressure.
Oral Expression
The TEF oral section is interactive and clearly structured in two parts, making preparation more predictable. The TCF includes three parts, including a longer open discussion, which may feel more challenging if you are not comfortable speaking spontaneously.
Listening Comprehension
In the TEF, you can read the questions before listening, which helps with focus. In the TCF, you listen without previewing the questions, which can make it more demanding.
Reading Comprehension
The reading sections are generally similar in format and difficulty.
Preparation
The TEF’s clear structure often makes preparation more strategic. The TCF may require broader practice due to its less predictable format.
Conclusion
Neither exam is objectively easier. The best choice depends on your strengths, your immigration goals, and how you prepare.
