Recently, in a test that realistically simulated the written portion of the teacher qualification exam, the Youdao AI Q&A Pen took part in the written exams for nine subjects of the teacher qualification certification. After the pen completed its on-site question-answering, the staff transcribed its answers. Subsequently, these answers underwent a collective review by experts and professional graders from prestigious universities like Beijing Normal University. The outcome revealed that the Youdao AI Q&A Pen successfully passed all nine subjects, marking it as the first AI to clear the written exam for teacher qualifications.
