Friend, a teacher's qualification certificate is a necessary certificate to be a teacher. But certificates are graded: primary school teacher qualification certificate, junior high school teacher qualification certificate and senior high school teacher qualification certificate. RTVU should belong to higher education, and the requirements will probably be higher! We are here to teach in colleges and universities, with at least a postgraduate degree! Of course, if RTVU passes the interview and pays attention to your real talent and learning, I believe it will be hired. Good luck!
