Reactivate Standard Certificate in Texas?

    I have a degree in English Education and live in Texas.
    After becoming certified with a standard certificate, I
    began a career in a different field and let my certificate
    expire. I've never taught and would like to reactivate my
    certificate at this time. Has anyone ever done this before?
    I am not finding a clear answer on the state board
    website. I'm not sure if I retest, catch up on 5 years
    worth of CEUs, or is there some other option?

    Thank you,
