There are 4 parts to renewing your ACE certification:
1) Fees: Renewals are for a 3-year calendar period. Save money on your ACE by being an ESA member at the time of renewal. Renewal fees are shown here.
2) PCO license: ACEs must submit a copy of a current state, federal, or tribal pesticide applicator's license at the time of renewal. The license must allow the applicator to apply pesticides without supervision, or whatever the highest level of license is in your area.
3) CEUs: All renewing ACEs must submit documentation of continuing education units earned during the 3 prior years. A list of eligible CEUs is listed here.
4) Sign the COE: At the time of renewal, all ACEs must reaffirm their understanding and adherence to the ACE Code of Ethics, which can be found here.
