The Toefl iBT(internet based test?) add the speaking section. How to evaluate your speaking? I got something from a practice book.
Our speaking can be evaluated from two aspects: content and language. The content of the speaking can be evaluated from follows. Do you address the topic? Does your speaking covers the main points? Are good examples contained? And do you have your ideas that connect well? In the same way, your response can be evaluated from four aspects as language too. You can estimate your speaking level by following standard. Are you free of hesitations? Do you exhibit clear pronunciation? Does your speaking incorporate effective vocabulary and correct grammar?
