No need. Stem education is a training institution, and the law does not directly stipulate whether teachers in training institutions should obtain teacher qualifications. Moreover, according to the classification of teacher qualification certificates in Article 4 of the Teacher Qualification Regulations, the current teacher qualification categories cannot correspond to the business of companies whose main business is training. For example, art education (including adults and children), STEAM education, study tour, vocational education (such as qualification training such as law examination, registered accountant, civil servant examination, institution examination, IT training, enterprise training, professional training), which can mainly correspond to discipline training in primary and secondary schools, art examination and postgraduate entrance examination closely related to academic education entrance examination. For another example, from the current public law enforcement situation, the education administrative department is mainly concerned about the situation that teachers who are engaged in training in Chinese, mathematics, English, physics, chemistry, biology and other disciplines in off-campus training institutions have obtained corresponding teacher qualifications, and has not found that teachers who are engaged in non-academic training such as art education, vocational education, STEAM education, and studying abroad have been sentenced to administrative punishment for not obtaining teacher qualifications. The current policy clearly requires that teachers engaged in subject education and teaching in off-campus training institutions in primary and secondary schools must obtain teacher qualification certificates. However, for art education, vocational education, STEAM education, study tour and other training, there is no direct and clear requirement to obtain teacher qualification certificate. To sum up, I don't think stem training teachers need to obtain teacher qualification certificate.
