If you have signed off 5 initial students for their checkride, and
have an 80% pass rate, you can take those appropriate records to your
local FSDO office and they will renew your license.

Even after the online stuff or the FSDO office you still have to do a
Flight Review. Finding a DPE or someone from the FSDO office to fly
with may save the most amount of time. You can get the CFIG renewal
and flight review all done at once.

At least that is what I do.
