Step-by-step explanation:
The format used for delivering PTDE (Parent Taught Driver Education) certificates by Aceable is Emailed.
After completing the requirements for the PTDE course, the certificate is electronically generated and sent to the student's email address provided during registration. This allows for a convenient and quick delivery of the certificate.
By using email as the delivery method, Aceable ensures that students can easily access and print their certificates, saving time and resources compared to traditional mailing or faxing options.
