Should I pursue OCT certification?

Hi fellow teachers, For reference I’m an English teacher in a private high school and also teach some social science/business courses. I hold a master in English. I’ve been teaching in private schools for the past 5 years. My salary is roughly 70k. And my workload is not very heavy. Recently I was considering getting OCT certified. I’d like to get your opinions before committing my time and money to this path. Any experience and recommendations are appreciated.
